Product details

Overview

MUR460SHR7G from Taiwan Semiconductor is a 4A, 600V ultra-fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 50 ns reverse recovery time, 1.25 V max forward voltage at 4A/25°C, and 75 A peak surge current; used for high-frequency freewheeling and output rectification in SMPS for telecom and computing.

For engineers reviewing the MUR460SHR7G datasheet, MUR460SHR7G pinout, MUR460SHR7G application, or MUR460SHR7G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (R_θJC = 8.5 °C/W), junction temperature range (–55 to +175 °C), and RoHS/halogen-free compliance for industrial power supply design.

Technical Context

This single-die ultra-fast rectifier uses glass-passivated junction technology to achieve low reverse recovery charge and minimal switching losses in high-frequency DC-DC converters. Its 50 ns trr and 65 pF junction capacitance support operation up to several hundred kHz without significant EMI or efficiency degradation.

The device operates across –55 °C to +175 °C junction temperature, with R_θJA = 45 °C/W on standard FR-4 PCB (1 sq-in copper pad), enabling reliable performance in thermally constrained SMT layouts. Cathode band marking and matte tin-plated leads ensure automated placement compatibility and J-STD-002 solderability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - blocks up to 600 V repetitive reverse voltage, suitable for 400 V DC bus applications with safety margin
I_F	4 A continuous - rated average forward current at T_C = 75 °C, defines steady-state conduction capability
t_rr	50 ns - ultra-fast recovery enables high-frequency switching (>200 kHz) with low switching loss in SMPS
V_F (max)	1.25 V @ 4 A, 25 °C - forward drop impacts conduction loss and thermal design in high-current paths
R_θJC	8.5 °C/W - junction-to-case thermal resistance supports direct heatsinking via PCB copper or external metal slug
I_FSM	75 A - non-repetitive surge rating handles inrush and transient overloads without failure
Junction temp	–55 to +175 °C - wide operating range allows use in automotive under-hood or industrial ambient conditions

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; t_rr = 55 ns; V_F = 1.3 V max @ 4 A	Slightly higher V_F and t_rr; lower I_FSM (60 A)	Acceptable where 5 ns t_rr margin is not critical and thermal headroom exists
ON Semi MUR460E	Identical electrical specs and DO-214AB package; same marking logic; RoHS-compliant	No functional difference; validated alternate sourcing for supply chain diversification	Drop-in replacement with identical layout, thermal, and electrical behavior

Compared with STTH4L06S, MUR460SHR7G offers tighter t_rr and lower V_F, improving efficiency in high-frequency designs; versus MUR460E, it shares identical performance but differs in date code format and reel packaging (HR7G denotes tape-and-reel with 7" reel and green compound).

FAQ

What is the maximum junction temperature rating for MUR460SHR7G?

The MUR460SHR7G has a maximum junction temperature (T_J) of +175 °C and a minimum of –55 °C. This wide range allows operation in demanding environments such as enclosed industrial enclosures or under-hood automotive auxiliary power modules. The MUR460SHR7G maintains specified electrical parameters across this full range when derated per the forward current derating curve in the datasheet.

Does MUR460SHR7G support lead-free reflow soldering?

Yes, MUR460SHR7G features matte tin-plated leads compliant with J-STD-002 for solderability and qualified for lead-free reflow profiles (JEDEC J-STD-020). Its moisture sensitivity level is Class 1, meaning no baking is required prior to assembly, simplifying manufacturing flow and reducing process risk for high-volume SMT lines using the MUR460SHR7G.

What is the reverse recovery time (t_rr) of MUR460SHR7G and how is it measured?

The MUR460SHR7G has a typical reverse recovery time (t_rr) of 50 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_RR = 0.25 A per the datasheet test circuit (Fig.6). This value is confirmed across the full temperature range and directly impacts switching loss in high-frequency converters-lower t_rr reduces diode-induced ringing and MOSFET voltage overshoot during turn-off events involving the MUR460SHR7G.

Is MUR460SHR7G halogen-free and RoHS compliant?

Yes, MUR460SHR7G is both RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and the device carries the "G" suffix in its marking (as in MUR460SHR7G) to denote green compound. This ensures environmental compliance for export to EU, China, and other regulated markets requiring MUR460SHR7G documentation.

What does the "HR7G" suffix in MUR460SHR7G indicate?

The "HR7G" suffix in MUR460SHR7G specifies packaging and material: "H" = tape-and-reel, "R7" = 7-inch reel, "G" = green (halogen-free) molding compound. It does not affect electrical specifications-MUR460SHR7G shares identical V_RRM, t_rr, V_F, and thermal ratings with other MUR460S variants. This suffix enables traceability and ensures correct material handling in green manufacturing workflows using MUR460SHR7G.
