Product details

Overview

MURS160 from Diodes Incorporated is a 1.0A surface-mount super-fast rectifier diode with 600V peak repetitive reverse voltage, 50ns reverse recovery time, and SMB package. It serves as a high-efficiency AC/DC input stage or DC-DC flyback snubber diode in compact power supplies, delivering low forward voltage (1.05V at 1.0A, 150°C) and robust surge capability (35A peak).

For engineers reviewing the MURS160 datasheet, MURS160 pinout, MURS160 application, or MURS160 equivalent, key selection criteria include its 600V V_RRM, 50ns t_rr, thermal resistance (15°C/W), cathode-band polarity marking, and RoHS-compliant matte tin terminals-critical for high-frequency switching, automotive-grade designs, and automated SMT assembly.

Technical Context

The MURS160 is a silicon planar epitaxial super-fast recovery rectifier optimized for high-frequency operation up to several hundred kHz. Its 50ns reverse recovery time and 10pF junction capacitance minimize switching losses and EMI generation in SMPS topologies.

Designed with glass-passivated die construction and rated for -55°C to +150°C junction operation, it supports reliable performance under thermal stress and transient overload conditions-including 35A non-repetitive surge current with 8.3ms half-sine waveform.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum blocking voltage before avalanche conduction; enables use in 400V AC input rectification with safety margin.
I_O	1.0 A - Average forward current at T_T = +135°C; defines continuous power handling in thermally constrained PCB layouts.
t_rr	50 ns - Reverse recovery time measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; ensures minimal tail current loss in 100–500 kHz converters.
V_FM	1.05 V @ 1.0A, 150°C - Forward voltage drop at max operating temperature; directly impacts conduction loss and thermal design.
R_θJT	15 °C/W - Junction-to-terminal thermal resistance with 5.0 mm² copper pad; determines temperature rise per watt under real mounting conditions.
I_FSM	35 A - Non-repetitive peak surge current (8.3ms half-sine); withstands inrush and line-transient events without failure.
C_T	10 pF @ 4V, 1MHz - Junction capacitance; influences high-frequency noise coupling and snubber sizing.

Pinout & Package

Applications

AC/DC Adapter Input Stage

Use Scenario: Rectifying 90–264V AC mains in compact wall adapters for consumer electronics.

IC Role / Device Role / Timing Role: Primary-side unidirectional current path; blocks reverse voltage while conducting forward current during positive half-cycles.

Use Value: 600V V_RRM provides 100% margin over 400V DC link; 50ns t_rr minimizes switching loss at 250 kHz operation.

Use Scenario: Input rectification in 12V battery-fed infotainment systems with load-dump protection.

IC Role / Device Role / Timing Role: High-reliability AC/DC front-end in automotive-grade DC-DC modules compliant with AEC-Q101.

Use Value: -55°C to +150°C operating range and 35A surge rating ensure robustness against cold cranking and ISO 7637-2 pulses.

Industrial PLC Power Module

LED Driver Flyback Snubber

Use Scenario: Secondary-side rectification in isolated 24V/48V PLC power supplies with wide ambient temperature range.

IC Role / Device Role / Timing Role: Output rectifier in flyback or forward converter; delivers regulated DC with low conduction loss.

Use Value: 1.05V V_FM at 150°C reduces thermal runaway risk; SMB footprint saves board space vs. DO-214AA.

Use Scenario: Snubber diode across MOSFET in LED driver flyback circuits operating at >100 kHz.

IC Role / Device Role / Timing Role: Clamp and redirect leakage energy during MOSFET turn-off; requires fast recovery and low C_T.

Equivalent & Alternatives

The following parts are listed as comparable options for similar super-fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L60	600V V_RRM, 1.05A I_O, 55ns t_rr, DO-214AC (SMA) package	Higher thermal resistance (25°C/W), larger footprint, no automotive-grade variant	Select when SMA mounting is preferred or legacy board layout requires DO-214AC form factor.
ES1J	600V V_RRM, 1.0A I_O, 35ns t_rr, SMB package, but only 25A I_FSM	Lower surge rating limits use in high-inrush applications; same footprint and polarity marking	Choose where faster recovery is prioritized over surge margin, e.g., low-power LED drivers.

Compared with STTH1L60 and ES1J, the MURS160 uniquely balances 35A surge capability, 50ns recovery, and SMB footprint-making it optimal for space-constrained, high-reliability industrial and automotive power supplies where both transient robustness and switching efficiency matter.

FAQ

What is the maximum junction temperature for continuous operation of the MURS160?

The MURS160 has a specified operating junction temperature range of -55°C to +150°C. For continuous operation at full 1.0A average current, the terminal temperature must not exceed +135°C per the derating curve. Thermal design must account for R_θJT = 15°C/W and PCB copper area to maintain safe junction temperatures under worst-case ambient and power dissipation conditions.

Is the MURS160 suitable for automotive applications?

The standard MURS160 is not qualified to AEC-Q101; however, the automotive-compliant variant MURS160Q is available under a separate datasheet and meets AEC-Q101 stress testing requirements. For non-automotive industrial or consumer applications, the MURS160 provides robust thermal and surge performance, but automotive deployment requires explicit use of the Q-grade part.

How does the 50ns reverse recovery time impact EMI in a 250kHz flyback converter?

A 50ns t_rr limits reverse recovery charge (Q_rr) and associated di/dt-induced ringing, reducing high-frequency EMI peaks above 30MHz. In a 250kHz flyback, this enables tighter control of MOSFET voltage overshoot and lowers filter component stress-particularly when paired with low-inductance PCB layout and proper snubber design.

Can the MURS160 replace a standard FR107 in an existing design?

Yes, the MURS160 can replace FR107 in many cases: both are 600V, 1A rectifiers. However, the MURS160's 50ns t_rr is significantly faster than FR107's ~500ns, reducing switching loss and EMI-but may increase voltage spikes if snubbers are not re-optimized. Also, SMB package differs from FR107's DO-41 through-hole form, requiring PCB redesign.
