MURS160T3G

Let me quickly introduce the MURS160T3G diode. It comes in an SMC (DO-214AB) package, ideal for automatic assembly. It handles up to 600V reverse voltage and supports a continuous current of 1A, with a surge rating up to 30A (for 8.3ms single pulse). With an ultra-fast recovery time of about 75ns, it’s great for switching circuits. Forward voltage drop is around 1.7V at 1A. Plus, it operates from -55°C to +150°C and has clear polarity markings for easy installation.

MURS160T3G Pinout

When using the MURS160T3G diode, always double-check the polarity—the cathode side (marked with a white stripe) shows you the correct orientation. Its SMC package has good heat conduction, so make sure the solder pad fits closely to the diode’s bottom for better cooling. Also, remember it only allows current flow in one direction. Reversing it might damage the diode or your circuit. With its ultra-fast recovery, it’s perfect for high-frequency rectification and freewheeling applications, outperforming regular diodes.

MURS160T3G Equivalent Fast Recovery Diode

For replacing the MURS160T3G diode, here’s what I’d recommend: For high-frequency applications needing super-fast recovery, go for STTH1R06 (25ns recovery). If you’re on a budget and don’t need high voltage, ES1G is a good choice—but it’s smaller (SMA) and rated for just 400V. Need something for high-voltage circuits? HER108G handles up to 1000V, with similar performance and matching package size.

MURS160T3G Rectifier Circuit Example

Check out this typical full-wave bridge rectifier circuit—it’s a perfect example for using the MURS160T3G diode. AC power enters from the left, then passes through four diodes that convert both positive and negative cycles into DC current for the load on the right. The MURS160T3G is great here because it’s ultra-fast (75ns), rated for 600V and 1A, making it ideal for high-frequency power adapters, switching power supplies, or motor protection circuits. For high-voltage AC (like 220V), adding a TVS or MOV protector is recommended. And if your current goes beyond 1A, consider upgrading to something like the MURS320T3G.

MURS160T3G SMPS Output Diode

For SMPS output rectification, especially in flyback or forward topologies, I’d suggest you try the MURS160T3G diode. Its ultra-fast recovery (about 75ns) cuts switching losses at high frequencies, making your circuit more efficient. With a high reverse voltage rating of 600V, it handles mid-to-high voltage outputs (like 24V or 48V) comfortably. Rated for 1A continuous current and 30A surge, it’s suitable for typical loads. Remember to add a low-ESR capacitor after the diode for smoother output ripple, and ensure proper heat dissipation through a good PCB layout. For currents above 1A, MURS320T3G or STTH1R06 are great alternatives.

MURS160T3G Freewheeling Diode Usage

MURS160T3G diode works great for protecting inductive loads like relays, coils, or motors. When your MOSFET or transistor switches off, inductors generate voltage spikes, and this diode quickly clamps that spike within about 75ns, protecting your circuit. It’s also excellent in buck converters or high-frequency PWM circuits, reducing switching losses. Connect it correctly—cathode (K) to the positive side, anode (A) towards the load. Its 600V rating and 1A current limit typically cover common applications nicely.

MURS160T3G High Frequency Inverter Circuit

This schematic shows you a typical full-bridge inverter circuit. DC input flows through four MOSFETs (Q1-Q4), creating high-frequency AC output. An LC filter smooths the waveform. Those diodes (D1-D4) near each MOSFET are essential—they clamp voltage spikes when MOSFETs switch off, protecting the circuit. MURS160T3G diodes work great here due to their ultra-fast recovery (~75ns), 600V rating, and 1A current capacity, ideal for frequencies from tens to over 100kHz. For higher-power needs, you might consider upgrading to something like the MURS320T3G.
