Product details
Overview
MUR460SHM6G from Taiwan Semiconductor is an ultra-fast recovery surface-mount rectifier diode rated for 4 A average forward current and 600 V repetitive peak reverse voltage, with 50 ns reverse recovery time and 1.25 V max forward voltage at 4 A and 25°C, used in high-frequency switching mode power supplies for telecom and computing applications.
For engineers reviewing the MUR460SHM6G datasheet, MUR460SHM6G pinout, MUR460SHM6G application, or MUR460SHM6G equivalent, key selection criteria include reverse recovery time, thermal resistance (RθJC = 8.5°C/W), junction temperature range (–55°C to +175°C), moisture sensitivity level (MSL 1), and DO-214AB (SMC) package compatibility with automated placement.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-efficiency DC-DC conversion and freewheeling in SMPS topologies. Its ultra-fast trr of 50 ns minimizes switching losses during turn-off, while the glass-passivated junction ensures stable operation under thermal cycling and humidity exposure.
The DO-214AB (SMC) package provides low thermal resistance (RθJA = 45°C/W) and supports high surge capability (IFSM = 75 A, 8.3 ms half-sine), making it suitable for transient-heavy environments such as AC/DC front-ends and DC bus clamping circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - blocks up to 600 V reverse voltage without breakdown, enabling use in 400 V DC bus systems with safety margin |
| IF | 4 A - continuous average forward current rating at TC = 115°C, defining steady-state conduction capability |
| trr | 50 ns - ultra-fast reverse recovery time reduces switching loss and EMI in >100 kHz converters |
| VF (max) | 1.25 V @ 4 A, 25°C - forward voltage drop directly impacts conduction loss and thermal design |
| RθJC | 8.5 °C/W - junction-to-case thermal resistance enables effective heatsinking via PCB copper or external metal slug |
| IFSM | 75 A @ 8.3 ms - peak non-repetitive surge current handling for inrush and fault conditions |
| Junction temp | –55°C to +175°C - wide operating temperature range supports industrial and telecom ambient requirements |

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; 4 A / 600 V; trr = 55 ns; VF = 1.3 V @ 4 A | Slightly higher VF and trr; identical thermal specs and footprint | Acceptable where <5 ns trr margin is not critical and ST sourcing preferred |
| ON Semi MUR460E | DO-214AB; 4 A / 600 V; trr = 50 ns; VF = 1.25 V @ 4 A; same MSL 1 rating | Functionally identical electrical performance; different marking and date code format | Drop-in alternative with validated compatibility in existing SMC layouts and thermal profiles |
Compared with STTH4L06S and ON Semi MUR460E, the MUR460SHM6G delivers identical ultra-fast recovery and forward voltage performance in the same DO-214AB package, but offers Taiwan Semiconductor's specific process control for tighter IR distribution and extended high-temperature reverse leakage stability.

FAQ
What is the maximum junction temperature rating for MUR460SHM6G?
The MUR460SHM6G has a maximum junction temperature (TJ) of +175°C and a minimum of –55°C. This wide range allows reliable operation in demanding industrial and telecom environments. The device's thermal resistance values-RθJC = 8.5°C/W and RθJA = 45°C/W-enable accurate thermal modeling when designing heatsinking or PCB copper pour. MUR460SHM6G must be operated within this junction temperature window to maintain specified electrical performance and lifetime.
Is MUR460SHM6G compatible with lead-free reflow soldering processes?
Yes, MUR460SHM6G is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound complies with UL 94V-0 flammability standards. The device is rated MSL 1 (moisture sensitivity level 1) per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly. MUR460SHM6G supports peak reflow temperatures up to 260°C for standard JEDEC profiles.
What does the 'HM6G' suffix indicate in MUR460SHM6G?
The 'HM6G' suffix in MUR460SHM6G denotes Taiwan Semiconductor's internal packaging and environmental compliance coding: 'H' indicates halogen-free compound per IEC 61249-2-21; 'M6' specifies tape-and-reel packaging with 3,000 units per reel; 'G' signifies green (RoHS-compliant) material formulation. This suffix distinguishes MUR460SHM6G from other variants like MUR460S (non-halogen-free) and confirms full regulatory alignment for global electronics manufacturing. MUR460SHM6G is the recommended version for modern eco-conscious designs.
How does the reverse recovery time of MUR460SHM6G compare to standard fast recovery diodes?
MUR460SHM6G has a reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This is approximately 2–3× faster than standard fast recovery diodes (typically 100–200 ns), significantly reducing switching loss and EMI in high-frequency converters. The ultra-fast trr enables MUR460SHM6G to operate efficiently in 200–500 kHz SMPS designs where conventional diodes would overheat or cause excessive ringing. MUR460SHM6G maintains this performance across its full temperature range.
Can MUR460SHM6G replace MUR460S in existing designs?
Yes, MUR460SHM6G is a direct replacement for MUR460S in most applications. Both share identical electrical specifications (600 V VRRM, 4 A IF, 50 ns trr, DO-214AB package), but MUR460SHM6G adds halogen-free and enhanced RoHS compliance. No PCB layout or thermal redesign is required. The 'HM6G' variant improves long-term reliability in humid environments due to its halogen-free molding compound and MSL 1 rating. MUR460SHM6G should be selected for new designs requiring full environmental compliance and extended field life.
