Product details

Overview

MUR460-T from Diodes Incorporated is a super fast glass passivated rectifier diode rated for 600 V repetitive peak reverse voltage and 4.0 A average forward current at 120°C lead temperature, featuring 50 ns reverse recovery time, 1.28 V forward voltage at 4 A, and AEC-Q101 Rev_C qualification for automotive-grade reliability in high-efficiency AC/DC front-end and flyback snubber circuits.

For engineers reviewing the MUR460-T datasheet, MUR460-T pinout, MUR460-T application, or MUR460-T equivalent, key selection criteria include reverse recovery time under 50 ns, thermal resistance (R_thJL = 11 °C/W), low leakage (<10 µA @ 25°C), RoHS- and halogen-free compliance, and DO-201AD package compatibility with high-power PCB layouts.

Technical Context

This device operates as a unidirectional power rectifier optimized for high-frequency switching applications up to 20 kHz, where fast recovery minimizes switching losses. Its glass passivation ensures stable junction performance across -55°C to +175°C operating range and supports reliable operation in automotive under-hood environments.

The DO-201AD package provides mechanical robustness and thermal path efficiency via low R_thJL (11 °C/W) and R_thJC (8 °C/W), enabling sustained 4.0 A conduction without forced cooling when mounted on copper-clad PCBs with adequate pad area.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Withstands peak reverse transients in 400 V AC line-derived supplies without breakdown.
I_F(AV)	4.0 A @ T_L = 120°C - Sustains continuous output in compact SMPS designs with natural convection cooling.
t_rr	50 ns - Enables efficient operation in 100–500 kHz switch-mode topologies with minimal tail current loss.
V_F	1.28 V @ I_F = 4 A, T_J = 25°C - Limits conduction loss to ~5.1 W at full load, easing thermal design.
I_R	10 µA @ V_R = 600 V, T_J = 25°C - Ensures negligible standby leakage in high-impedance hold-up circuits.
R_thJL	11 °C/W - Allows junction-to-lead temperature rise of 44°C at 4 A, supporting reliable long-term operation.

Pinout & Package

Package: DO-201AD molded plastic case per JEDEC standard; cathode indicated by color band; weight ≈ 1.0675 g; UL 94V-0 flammability rating.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead A)	Positive input terminal for forward conduction	Connected to AC source or transformer secondary; must handle full surge current (220 A @ 1 ms).
Cathode (Lead K, banded end)	Output terminal for rectified DC	Drives bulk capacitor or downstream regulator; polarity marking prevents reverse installation in high-reliability assemblies.

Key Features

Feature	Design Value
Glass passivated chip	Eliminates moisture-induced degradation and enables stable parametric performance over 15+ year automotive service life.
AEC-Q101 Rev_C qualification	Validated for automotive powertrain and body electronics requiring zero-defect reliability under thermal cycling and humidity bias stress.

Halogen- and antimony-free "Green" construction	Meets EU Directive 2015/863/EU with Br+Cl <1500 ppm and Sb <1000 ppm-enabling compliance in export-sensitive markets.

Applications

AC/DC Power Supply Input Stage

Automotive DC-DC Converter Output Rectification

Use Scenario: Full-wave bridge rectification in 100–250 W offline SMPS with universal input (85–265 V AC).

IC Role / Device Role / Timing Role: Primary unidirectional power switch converting AC line to pulsating DC; operates at 50/60 Hz fundamental but recovers within 50 ns for high-frequency noise suppression.

Use Value: 50 ns t_rr reduces EMI generation during commutation, lowering filter component count and board area by ~18% vs. standard FR diodes.

Use Scenario: Secondary-side synchronous rectification replacement in 12 V → 5 V/3.3 V automotive buck converters.

IC Role / Device Role / Timing Role: Freewheeling diode clamping inductive kickback during MOSFET off-time; handles 4 A average load with minimal voltage overshoot.

Use Value: 1.28 V V_F limits conduction loss to ≤5.1 W, permitting operation without heatsink in ambient up to 85°C.

Flyback Snubber Network

Industrial Motor Drive Brake Circuit

Use Scenario: RC clamp snubber across primary-side MOSFET in isolated flyback converters handling >100 W loads.

IC Role / Device Role / Timing Role: Fast recovery path for transient energy dissipation; conducts brief high-di/dt pulses during MOSFET turn-off.

Use Value: 220 A non-repetitive surge rating (1 ms) absorbs single-event spikes without degradation, extending MOSFET lifetime.

Use Scenario: Dynamic braking path for 24 V DC brushed motors in factory automation systems.

IC Role / Device Role / Timing Role: Regenerative energy return diode routing back EMF into supply rail during deceleration.

Use Value: -55°C to +175°C operating range ensures functionality during cold-start and hot-soak conditions in enclosed control cabinets.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH4L06D	Same DO-201AD package; t_rr = 55 ns (slower), V_F = 1.3 V @ 4 A	Marginally higher conduction loss; not AEC-Q101 qualified	Acceptable for industrial non-automotive use where qualification is not mandated.
ES4D-E3/57T	DO-214AA (SMA) package; t_rr = 35 ns (faster), I_F(AV) = 4.0 A, V_F = 1.25 V	Smaller footprint but lower thermal mass; R_thJA = 45 °C/W vs. 30 °C/W for MUR460-T	Preferred for high-density layouts where board space is critical and thermal derating is managed.

Compared with STTH4L06D and ES4D-E3/57T, MUR460-T uniquely balances AEC-Q101 compliance, 50 ns recovery, and DO-201AD thermal performance-making it optimal for automotive and high-reliability industrial rectification where qualification and thermal margin are jointly required.

FAQ

What is the maximum allowable junction temperature for MUR460-T?

The absolute maximum junction temperature is +175°C, with continuous operation supported from -55°C to +175°C. Derating curves confirm 4.0 A average current is sustainable only when lead temperature remains ≤120°C-requiring appropriate PCB copper area or thermal relief design to maintain this limit.

Is MUR460-T suitable for use in synchronous rectification topologies?

No-MUR460-T is a passive diode and cannot be actively controlled like a MOSFET. It serves as a freewheeling or clamp diode in non-synchronous designs. For synchronous rectification, discrete N-channel MOSFETs with gate drivers are required; this part replaces them only in legacy or cost-optimized non-synchronous implementations.

How does the DO-201AD package affect thermal performance compared to SMD alternatives?

DO-201AD offers superior thermal conduction to PCB copper via axial leads (R_thJL = 11 °C/W), outperforming most SMD packages like SMA (R_thJA ≈ 45 °C/W). However, it requires through-hole mounting and occupies more board area-making it ideal for high-power through-hole designs where thermal density outweighs layout constraints.

Does MUR460-T require derating when operated at elevated ambient temperatures?

Yes-derating is mandatory above 25°C ambient. Figure 6 shows peak surge current drops from 220 A at 25°C to 150 A at 125°C. For continuous operation, Figure 1 mandates linear reduction from 4.0 A at 120°C lead temperature to zero at 175°C-so ambient temperature rise must be managed via thermal design to avoid exceeding T_L limits.
