Product details

Overview

MUR460-M3/54 from Vishay General Semiconductor is an ultrafast plastic rectifier diode in DO-201AD package, rated for 600 V repetitive peak reverse voltage (V_RRM), 4.0 A average forward current (I_F(AV)), and 50 ns typical reverse recovery time (t_rr), used for high-frequency freewheeling and output rectification in SMPS and inverters.

For engineers reviewing the MUR460-M3/54 datasheet, MUR460-M3/54 pinout, MUR460-M3/54 application, or MUR460-M3/54 equivalent, key selection criteria include its 600 V blocking capability, 150 A non-repetitive surge rating, low 1.05 V forward voltage at 3.0 A and 150 °C junction temperature, halogen-free RoHS-compliant construction, and DO-201AD thermal performance (R_θJA = 28 °C/W).

Technical Context

The MUR460-M3/54 employs a glass-passivated silicon junction optimized for ultrafast switching, with reverse recovery time tightly specified at 50 ns (typ.) under I_F = 0.5 A / I_R = 1.0 A / I_rr = 0.25 A test conditions. Its low forward voltage drop and low leakage current (<10 µA at 25 °C) support high-efficiency operation in high-frequency DC-DC converters.

Designed for commercial-grade operation across –65 °C to +175 °C junction temperature range, it features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and passes JESD 201 Class 1A whisker testing. The DO-201AD case meets UL 94 V-0 flammability rating.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports input rectification in 400 VAC line-derived SMPS and industrial DC bus applications
I_F(AV)	4.0 A - continuous DC output current capability with derating above 50 °C ambient on standard PCB layout
t_rr (typ.)	50 ns - enables efficient operation up to ~200 kHz switching frequencies with minimal switching loss
V_F @ 3.0 A, 150 °C	1.05 V - reduces conduction loss and thermal stress in high-temperature power stages
I_FSM	150 A - withstands short-duration inrush and fault currents in offline power supplies
R_θJA	28 °C/W - defines thermal rise over ambient for TO-220–sized heatsinking or copper pad design
Junction Temp Range	–65 °C to +175 °C - supports extended-temperature deployment in automotive under-hood or industrial motor drives

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultrafast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH4L06S	Same DO-201AD package, 600 V V_RRM, but t_rr = 65 ns (max), V_F = 1.15 V @ 4 A / 150 °C	Slightly higher conduction and switching loss; suitable where 15 ns slower recovery is acceptable	Preferred when STMicroelectronics supply chain alignment is required and 10% higher V_F is tolerable
ON Semiconductor MUR460E-E3/54	Identical electrical specs and DO-201AD package; differs only in halogen content (E3 = RoHS + Pb-free, not halogen-free)	No functional difference; substitution requires verification of halogen-free compliance in final BOM	Select when halogen-free certification is not mandated and E3-suffix sourcing is more available

Compared with STTH4L06S and MUR460E-E3/54, the MUR460-M3/54 delivers the lowest verified t_rr (50 ns typ.) and tightest V_F spec at high temperature among DO-201AD 4 A / 600 V ultrafast diodes, while ensuring halogen-free compliance for strict environmental programs.

FAQ

What is the maximum junction temperature rating for the MUR460-M3/54?

The MUR460-M3/54 has a maximum junction temperature (T_J) rating of +175 °C, enabling reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive auxiliary systems. This rating is validated per Vishay's thermal characterization and must be maintained via appropriate PCB copper area or heatsinking to limit R_θJA to 28 °C/W. The MUR460-M3/54 achieves full-rated I_F(AV) only when thermal design ensures T_J remains within this limit.

Does the MUR460-M3/54 have a halogen-free construction?

Yes, the MUR460-M3/54 is explicitly designated as halogen-free, RoHS-compliant, and commercial grade per Vishay's ordering nomenclature (M3 suffix). This includes bromine- and chlorine-free molding compound and lead finish, meeting IPC-1752A reporting requirements. The MUR460-M3/54 differs from E3-suffix variants, which are RoHS-compliant but not halogen-free. Compliance documentation is available upon request for the MUR460-M3/54.

What is the reverse recovery time specification for the MUR460-M3/54?

The MUR460-M3/54 has a typical reverse recovery time (t_rr) of 50 ns under test conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. Its maximum t_rr is 75 ns under more stressful conditions (I_F = 1.0 A, dI/dt = 50 A/μs). This ultrafast recovery enables efficient operation in 100–300 kHz switching power supplies. The MUR460-M3/54's t_rr is measured and guaranteed per the datasheet, not derived or estimated.

Can the MUR460-M3/54 replace the MUR440 in a 400 V design?

No - the MUR460-M3/54 is rated for 600 V V_RRM, while the MUR440 is rated for 400 V. Substituting the MUR460-M3/54 into a 400 V design is electrically permissible and may improve margin, but it does not functionally replace the MUR440 unless the circuit specifically requires 600 V blocking. The MUR460-M3/54 shares identical package, thermal, and forward characteristics with the MUR440, but its higher voltage rating does not imply compatibility in all 400 V layouts without verifying layout-induced voltage overshoot.

What packaging format is supplied for the MUR460-M3/54?

The MUR460-M3/54 is supplied in 13-inch diameter paper tape and reel packaging, with a base quantity of 1400 units per reel (package code "54"). This format is optimized for automated SMT placement after axial lead forming and taping. The MUR460-M3/54 reel conforms to EIA-481 standards and includes moisture-sensitive level (MSL) labeling per J-STD-020, though the DO-201AD package is not moisture-sensitive and does not require baking prior to assembly.
