Product details
Overview
MURS320-13-F from Diodes Incorporated is a 3.0A, 200V super-fast recovery surface-mount rectifier diode in SMC package, featuring 25ns reverse recovery time, 0.875V forward voltage at 3.0A/25°C, and 75A non-repetitive surge rating - deployed in high-frequency switch-mode power supplies and DC-DC converters.
For engineers reviewing the MURS320-13-F datasheet, MURS320-13-F pinout, MURS320-13-F application, or MURS320-13-F equivalent, key selection criteria include reverse recovery time (25ns), thermal resistance (11°C/W), peak repetitive reverse voltage (200V), average forward current (3.0A at TL=140°C), and RoHS-compliant lead-free plating.
Technical Context
This super-fast rectifier uses glass-passivated die construction to achieve tight parameter control and reliability under thermal cycling. Its 25ns trr and low 45pF junction capacitance enable efficient operation in 100–500kHz SMPS topologies where switching losses must be minimized.
The device operates across –65°C to +175°C with a 11°C/W junction-to-lead thermal resistance when mounted on 5.0mm² copper pads. It sustains 75A surge current for 8.3ms half-sine wave and exhibits only 5.0μA peak reverse leakage at 25°C and rated blocking voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage before breakdown; defines safe operating limit in bridge or flyback snubber circuits |
| IO | 3.0 A @ TL = 140°C - Continuous average forward current capability with proper PCB heat sinking |
| trr | 25 ns - Reverse recovery time measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; critical for minimizing switching loss in high-frequency converters |
| VFM | 0.875 V @ IF = 3.0A, TJ = 25°C - Forward voltage drop directly impacts conduction loss and thermal design margin |
| RθJL | 11 °C/W - Junction-to-lead thermal resistance with specified 5.0 mm² copper pad; enables accurate junction temperature estimation |
| CT | 45 pF @ 1.0 MHz, 0 V - Junction capacitance affects high-frequency noise coupling and EMI filter design |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with UL 94V-0 flammability rating, cathode band polarity marking, and matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| AC-DC Adapter Front-End | DC-DC Converter Output Rectification |
|---|---|
Use Scenario: Rectifying 50/60Hz or high-frequency AC input in compact wall adapters and open-frame power supplies. IC Role / Device Role / Timing Role: Primary-side unidirectional current steering device converting AC to pulsating DC prior to bulk filtering.

IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode clamping in forward or flyback topologies. Use Value: Low 0.875V VFM minimizes conduction loss at full load; 45pF CT limits capacitive coupling into sensitive feedback networks. |
| Industrial Motor Drive Snubber | LED Driver Power Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L02S | Same 200V VRRM, 3A IO, but 35ns trr and higher 1.05V VFM at 3A/25°C | Slightly higher conduction and switching loss; less suitable for >250kHz designs | Prefer when cost sensitivity outweighs efficiency targets in low-frequency industrial PSUs |
| ES3D | Lower 200V VRRM but only 3A IO and 35ns trr; TO-220AC package vs. SMC | Requires through-hole assembly and larger board area; no RoHS-compliant green compound | Select only if legacy through-hole layout prohibits SMD adoption or thermal mass requirement exceeds SMC capability |
Compared with STTH3L02S and ES3D, the MURS320-13-F delivers superior high-frequency efficiency via its 25ns trr and lower VFM, while its SMC package and RoHS/halogen-free construction better suit automated, space-constrained, and environmentally regulated designs.

FAQ
What is the maximum junction temperature for continuous operation?
The MURS320-13-F has an operating junction temperature range of –65°C to +175°C. For continuous operation at rated 3.0A average forward current, the terminal temperature must not exceed 140°C per the derating curve - achieved using minimum 5.0 mm² copper pad area per lead to maintain RθJL = 11°C/W.
Is the MURS320-13-F suitable for use in automotive applications?
The MURS320-13-F meets AEC-Q101 stress-test requirements for discrete diodes and operates across –65°C to +175°C, making it suitable for under-hood automotive auxiliary power supplies and body-control module power rails - provided system-level validation confirms immunity to ISO 7637-2 transients and board-level thermal management.
How does the 25ns reverse recovery time impact EMI performance?
A 25ns trr reduces high-frequency ringing during diode turn-off by limiting the duration of reverse recovery current overshoot, thereby lowering radiated emissions near the switching node. This allows simpler EMI filter designs in compact power supplies compared to standard fast recovery diodes with >50ns trr.
Can this diode replace a standard FR series rectifier in an existing design?
Yes - the MURS320-13-F is a direct SMC-package replacement for FR302–FR307 series diodes with identical pinout and footprint, but offers 25ns trr versus 50–100ns and lower VFM, delivering measurable efficiency gains in 100–300kHz designs without layout changes.
