Product details
Overview
MURS160-13 from Diodes Incorporated is a 1.0A surface-mount super-fast rectifier diode with 600V peak repetitive reverse voltage (VRRM), 1.25V forward voltage at 1.0A/25°C, and 50ns reverse recovery time (trr), designed for high-frequency switching power supplies, AC/DC adapters, and offline SMPS output rectification.
For engineers reviewing the MURS160-13 datasheet, MURS160-13 pinout, MURS160-13 application, or MURS160-13 equivalent, key selection criteria include its 600V blocking capability, 35A non-repetitive surge rating, SMB package thermal resistance of 13K/W, and glass-passivated die construction for reliability in automated assembly environments.
Technical Context
This super-fast rectifier employs a planar epitaxial silicon junction with glass passivation to achieve low trr (50ns) and stable IRM (150µA at 150°C), enabling efficient operation in 100–500kHz switch-mode topologies where reverse recovery losses must be minimized.
Its SMB package supports PCB-mounted heat sinking via 5.0mm² copper pads, delivering 2.0A average forward current at 125°C terminal temperature - critical for compact, convection-cooled power converters requiring high power density without forced airflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600V - Sustains full-rated reverse voltage in bridge or flyback output stages without breakdown under transient overvoltage conditions. |
| IO @ TT=125°C | 2.0A - Maximum continuous DC output current achievable with 125°C terminal temperature, enabling higher load capacity than standard 1A rectifiers. |
| VFM @ 1.0A/25°C | 1.25V - Forward conduction loss directly impacts efficiency; lower than Schottky alternatives but with superior voltage rating. |
| trr | 50ns - Enables use in high-frequency SMPS (>200kHz) with minimal switching loss and EMI generation during turn-off. |
| IFSM | 35A - Withstands single half-sine surge events (8.3ms, 60Hz), supporting robust inrush current handling in AC-input front ends. |
| RJT | 13K/W - Thermal resistance from junction to terminal allows accurate thermal design when mounted on specified 5.0mm² copper pad area. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode-banded polarity, UL 94V-0 molded plastic case, solderable terminals per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to transformer secondary or switching node; must handle 35A surge peaks without bond wire failure. |
| Cathode | Forward current exit / reverse voltage reference | Marked with band or notch; ties to output capacitor ground or common return; defines polarity in full-wave configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Eliminates moisture-induced leakage degradation and improves long-term reliability in humid industrial environments. |
| Super-fast 50ns recovery | Reduces reverse recovery charge (Qrr) to <15nC, lowering switching losses in high-frequency flyback and LLC resonant converters. |
| SMB package with 13K/W RθJT | Enables 2.0A continuous current at 125°C terminal temp using only PCB copper as heatsink - no external heatsink required. |
| 35A IFSM surge rating | Supports direct connection to unfiltered rectified AC line or transformer secondaries without series fusing in many designs. |
Applications
| AC/DC Adapter Output Rectification | Offline Flyback Converter Secondary |
|---|---|
Use Scenario: 12V/2A universal input AC/DC adapter for consumer electronics. IC Role / Device Role / Timing Role: Output rectifier conducting DC current after high-frequency transformer secondary winding. Use Value: 50ns trr minimizes switching loss at 250kHz operation, improving efficiency by ~1.2% vs. standard fast rectifiers. | Use Scenario: 5V/3A isolated flyback supply in industrial IoT gateway. IC Role / Device Role / Timing Role: Unidirectional current path from transformer secondary to output capacitor, blocking reverse voltage during MOSFET on-time. Use Value: 600V VRRM provides 2× safety margin over reflected 300V spike, eliminating need for snubber clamping. |
| USB PD Power Delivery Front-End | Programmable Logic Controller (PLC) Power Module |
Use Scenario: 20V/5A USB PD 3.0 compliant charger with dual active-clamp flyback. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement in cost-sensitive designs where gate drive complexity is avoided. Use Value: 1.25V VFM at 1.0A yields lower conduction loss than 40V Schottkys while maintaining 600V isolation integrity. | Use Scenario: 24V/1.5A auxiliary power rail in DIN-rail mounted PLC with wide ambient range (-40°C to +70°C). IC Role / Device Role / Timing Role: Input rectifier for internal DC-DC stage fed from 24VAC control power source. Use Value: -65°C to +175°C operating range ensures functionality during reflow and field operation without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | Same 600V VRRM, 1.3V VFM, but 75ns trr and TO-277 package (higher RθJA). | Requires larger PCB footprint and additional thermal vias for equivalent 2.0A current handling. | Prefer when legacy TO-277 layout exists and 25ns slower recovery is acceptable. |
| ES1J-M3/84A | 600V VRRM, 1.7A IO@125°C, but 35ns trr and 1.7V VFM; SMB package identical. | Higher forward drop increases conduction loss in high-duty-cycle outputs; better for ultra-high-frequency (<1MHz) apps. | Choose when trr <40ns is mandatory and 0.45V higher VFM is tolerable in thermal budget. |
Compared with STTH1R06U and ES1J-M3/84A, MURS160-13 delivers optimal balance of low VFM (1.25V), fast trr (50ns), and SMB thermal performance (2.0A @ 125°C), making it preferred for space-constrained, medium-frequency SMPS where efficiency and board area are co-optimized.

FAQ
What is the maximum allowable junction temperature for MURS160-13?
The absolute maximum junction temperature is +175°C, with continuous operation rated up to +150°C junction temperature. Derating begins at +125°C terminal temperature, where average forward current drops to 2.0A - verified per JEDEC test conditions using 5.0mm² copper pad heat sinking.
Can MURS160-13 replace a Schottky diode in a 5V/3A output stage?
Yes, if reverse voltage exceeds 45V - MURS160-13's 600V rating provides ample margin where Schottkys fail. However, its 1.25V VFM increases conduction loss versus a 0.5V Schottky; use only when high-voltage blocking or elevated temperature stability (>125°C) is required.
Is MURS160-13 lead-free and RoHS compliant?
Yes, MURS160-13 meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound, certified per Diodes Incorporated's AP02007 packaging specification and IPC-J-STD-609B material declarations.
Does the SMB package support reflow soldering per J-STD-020?
Yes, MURS160-13 is qualified for standard Pb-free reflow profiles (peak 260°C, 20–40 sec above 217°C), with solderable terminals meeting MIL-STD-202 Method 208 and verified thermal cycling reliability across -65°C to +175°C operating range.
