Product details
Overview
MUR460SH from Taiwan Semiconductor is an ultra-fast recovery surface-mount rectifier diode rated for 600 V repetitive peak reverse voltage, 4 A average forward current, and 75 A non-repetitive surge current, with 50 ns reverse recovery time and 1.25 V max forward voltage at 4 A and 25°C - used in automotive DC-DC converters and snubber circuits.
For engineers reviewing the MUR460SH datasheet, MUR460SH pinout, MUR460SH application, or MUR460SH equivalent, key selection criteria include VRRM = 600 V, trr = 50 ns, IF = 4 A, RθJC = 8.5 °C/W, and DO-214AB (SMC) package compatibility with automated SMT assembly.
Technical Context
The MUR460SH is a single-die, silicon planar junction ultra-fast rectifier optimized for high-frequency switching applications where low reverse recovery charge and minimal forward conduction loss are critical. Its glass-passivated chip junction ensures reliability under thermal cycling and humidity stress.
Designed for AEC-Q101 qualification, it supports automotive-grade operation across -55°C to +175°C junction temperature range, with moisture sensitivity level 1 (J-STD-020) and halogen-free molding compound compliant with IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage without breakdown, enabling use in 400 V DC bus systems with safety margin |
| IF | 4 A - continuous average forward current at TC = 110°C, defining steady-state power handling capability |
| trr | 50 ns - ultra-fast reverse recovery time, minimizing switching losses in 100–500 kHz SMPS topologies |
| VF (max) | 1.25 V @ 4 A, 25°C - forward voltage drop directly impacts conduction loss and thermal rise in high-current paths |
| RθJC | 8.5 °C/W - junction-to-case thermal resistance enables efficient heat transfer to PCB copper or heatsink in SMC package |
| IFSM | 75 A - peak non-repetitive surge current (8.3 ms half-sine), supporting inrush and fault transient tolerance |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, single-anode/single-cathode configuration with cathode band marking. Matte tin-plated leads, UL 94V-0 molded compound, 0.250 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead 1) | Forward current entry point | Connected to lower-potential side of circuit; must be routed with adequate copper area for 4 A continuous current |
| Cathode (lead 2, banded end) | Forward current exit / reverse blocking terminal | Marked by molded cathode band; connects to higher-potential node and carries full reverse voltage during off-state |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TC, HAST, and UHAST |
| Glass passivated junction | Provides hermetic protection against humidity and contamination, extending lifetime in harsh under-hood environments |
| Ultra-fast 50 ns recovery | Reduces reverse recovery energy (Erec) and associated EMI in high-frequency flyback and boost converters |
| Moisture sensitivity level 1 | Enables standard SMT reflow without baking, lowering manufacturing cost and cycle time |
Applications
| Automotive DC-DC Converters | LED Headlamp Drivers |
|---|---|
Use Scenario: High-efficiency 12 V to 48 V bidirectional DC-DC conversion in 48 V mild-hybrid architectures. IC Role / Device Role / Timing Role: Output rectifier in synchronous or asynchronous buck-boost topology, handling 4 A continuous output current. Use Value: 50 ns trr minimizes switching loss and improves efficiency >94% at 250 kHz; 600 V rating accommodates load-dump transients up to 58 V. | Use Scenario: Constant-current LED driver for adaptive front lighting systems (AFS) with PWM dimming. IC Role / Device Role / Timing Role: Freewheeling diode across inductive LED choke during PWM off-cycle. Use Value: Low VF (1.25 V max) reduces conduction loss in high-duty-cycle operation; AEC-Q101 qualification ensures reliability over 15-year vehicle life. |
| Snubber Networks | Industrial AC-DC PFC Front-Ends |
Use Scenario: RCD snubber across MOSFET/IGBT switches in motor drives and inverters. IC Role / Device Role / Timing Role: Fast-recovery clamp diode that absorbs turn-off voltage spikes and limits dV/dt stress. Use Value: 50 ns trr prevents snap-off oscillation and secondary breakdown; 75 A IFSM withstands repetitive clamping energy pulses. | Use Scenario: Boost diode in active PFC stage of industrial power supplies (e.g., 3 kW server PSUs). IC Role / Device Role / Timing Role: Output rectifier conducting at line frequency harmonics up to 20 kHz. Use Value: 600 V VRRM supports universal input (85–265 VAC) with margin; DO-214AB package allows high-density layout with low parasitic inductance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH4L06S | Same DO-214AB package, 600 V VRRM, but trr = 35 ns (faster), VF = 1.7 V (higher), IF = 4 A | Better for <100 kHz ZVS designs requiring lowest Erec; less optimal where conduction loss dominates | Select STTH4L06S when switching loss reduction outweighs forward loss penalty |
| ES4D | DO-214AB, 600 V, trr = 75 ns (slower), VF = 1.15 V (lower), IF = 4 A, not AEC-Q101 qualified | Suitable for industrial/commercial SMPS where automotive qualification is unnecessary | Choose ES4D for cost-sensitive non-automotive applications needing lower VF and relaxed reliability requirements |
Compared with STTH4L06S and ES4D, the MUR460SH delivers balanced performance: AEC-Q101 compliance and 50 ns trr support automotive-grade robustness without excessive forward loss, making it optimal for 100–300 kHz DC-DC and snubber use cases where both switching and conduction efficiency matter.

FAQ
What is the maximum junction temperature rating for the MUR460SH?
The MUR460SH has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table. This allows operation in under-hood automotive environments and high-temperature industrial enclosures. Derating curves confirm usable current capacity down to TC = 110°C at full 4 A rating. Thermal design must maintain TJ ≤ 175°C under worst-case ambient and power dissipation conditions for the MUR460SH.
Is the MUR460SH pin-compatible with other devices in the MUR4xxSH family?
Yes - all MUR420SH through MUR460SH share identical DO-214AB (SMC) package dimensions, lead pitch, and anode/cathode terminal assignment. The MUR460SH can replace lower-voltage variants (e.g., MUR440SH) in existing layouts without PCB modification, provided system-level VRRM margin and thermal design accommodate the higher voltage rating's slightly increased VF.
Does the MUR460SH meet automotive qualification standards?
Yes - the MUR460SH is explicitly AEC-Q101 qualified per the manufacturer's datasheet, covering stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress testing (UHAST). This certification validates its suitability for automotive powertrain, body control, and lighting modules where reliability over 15 years is required.
What is the reverse recovery time (trr) specification for the MUR460SH?
The MUR460SH has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A per JEDEC test conditions. This value is confirmed in the Electrical Specifications table and applies across the full operating temperature range. Designers should use this trr to calculate switching loss and EMI in high-frequency topologies using the MUR460SH.
How is polarity indicated on the MUR460SH package?
Polarity on the MUR460SH is indicated by a molded cathode band located at one end of the DO-214AB (SMC) case. The banded end corresponds to the cathode terminal; the opposite lead is the anode. This marking is consistent with industry-standard diode polarity identification and aligns with the pinout diagram in the MUR460SH datasheet mechanical drawings.
