Product details
Overview
MURHD560W1T4G from onsemi is an ultrafast power rectifier diode in DPAK (TO-252) package, rated for 600 V peak repetitive reverse voltage, 5.0 A average forward current at TC = 159°C, and 30 ns reverse recovery time - enabling high-efficiency switching in AC/DC front-ends and DC/DC flyback converters.
For engineers reviewing the MURHD560W1T4G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, thermal performance data, AEC-Q101 qualification status, and real-world use context for automotive-grade power supply design and industrial inverter free-wheeling circuits.
Technical Context
This device is a single-die, planar, glass-passivated silicon junction diode optimized for ultrafast soft recovery. Its 30 ns trr (measured at IF = 1.0 A, di/dt = 50 A/μs, VR = 30 V, TJ = 25°C) and low Qrr support reduced switching losses in high-frequency SMPS topologies.
Rated for continuous operation up to TJ = +175°C with RJC = 2.5°C/W, the MURHD560W1T4G supports thermally demanding environments such as under-hood automotive power modules and industrial motor drive snubbers where sustained 125–150°C case temperatures are typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak line transients in universal-input 85–265 VAC supplies without avalanche breakdown. |
| IF(AV) | 5.0 A at TC = 159°C - Supports continuous conduction mode operation in 100–200 W offline converters with minimal heatsinking. |
| trr | 30 ns - Enables >100 kHz switching frequencies while limiting diode reverse recovery loss and EMI generation. |
| TJ max | +175°C - Allows integration into compact, sealed enclosures without derating at ambient temperatures up to +105°C. |
| RJC | 2.5°C/W - Delivers 20 W dissipation capability with ≤50°C temperature rise above case when mounted on 700 mm² copper pad. |
| VF @ 5A, 25°C | 2.7 V - Defines conduction loss baseline; VF drops to 1.65 V at 125°C, easing thermal management in high-temp operation. |
| IR @ 600V, 125°C | 70 µA - Low leakage preserves efficiency in high-voltage hold-off stages like PFC boost output clamps. |
Pinout & Package
DPAK (TO-252-3) package, case outline 369C, with exposed drain tab (pin 2 and pin 4) serving as cathode connection and thermal path. Molded epoxy body meets UL 94 V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main AC input terminal; connects to transformer secondary or switch node in flyback/flywheel configurations. |
| Pin 2 | Cathode | Primary output return path and thermal interface; soldered directly to PCB copper pour for heat extraction. |
| Pin 3 | Anode | Redundant anode connection - electrically tied to Pin 1 internally; improves current sharing and mechanical robustness. |
| Pin 4 | Cathode | Second cathode terminal - parallel-connected to Pin 2; enhances thermal conduction and reduces bond wire inductance. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R06DJF | Same 600 V / 8 A rating but TO-220FP package; higher IF(AV) = 8 A, slower trr = 45 ns, RJC = 3.5°C/W. | Better for higher-current, lower-frequency (<50 kHz) designs; less suitable for space-constrained SMT layouts. | Select when board area allows through-hole mounting and thermal budget permits higher RJC. |
| IXYS MUR1560CT | 600 V / 15 A dual common-cathode configuration in TO-220AB; trr = 35 ns; not AEC-Q101 qualified. | Targets dual-output or interleaved PSUs; lacks automotive qualification and has larger footprint. | Choose only for non-automotive, high-current dual-channel applications where AEC-Q101 is not required. |
Compared with STTH8R06DJF and IXYS MUR1560CT, the MURHD560W1T4G offers superior thermal resistance (2.5 vs. 3.5/4.0°C/W), AEC-Q101 compliance, and smallest SMT footprint - making it optimal for automotive OBCs and compact industrial SMPS where reliability, size, and thermal performance are jointly critical.

FAQ
What is the maximum junction temperature rating for the MURHD560W1T4G?
The MURHD560W1T4G is rated for continuous operation up to +175°C junction temperature. This specification is validated per onsemi's thermal characterization and enables reliable use in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 105°C. The MURHD560W1T4G maintains full electrical performance within this range when thermal design adheres to RJC = 2.5°C/W limits.
Is the MURHD560W1T4G AEC-Q101 qualified?
Yes, the MURHD560W1T4G is AEC-Q101 qualified and PPAP capable. It carries the SURHD8 prefix designation indicating compliance with automotive-grade process controls, lot traceability, and failure rate validation per AEC-Q101 Rev D. This qualification applies specifically to the MURHD560W1T4G variant, not just the generic MURHD560 family.
What is the reverse recovery time (trr) of the MURHD560W1T4G and under what test conditions?
The MURHD560W1T4G has a maximum reverse recovery time of 30 ns, measured under standardized conditions: IF = 1.0 A, di/dt = 50 A/μs, VR = 30 V, and TJ = 25°C. This value is confirmed in the official onsemi datasheet revision 11 (January 2025) and reflects actual device behavior in high-frequency switching applications such as 100–200 kHz SMPS designs.
How does the MURHD560W1T4G differ from the MURHD560T4G?
The MURHD560W1T4G and MURHD560T4G share identical electrical specifications and DPAK packaging, but differ in marking and traceability: MURHD560W1T4G uses "560W1" marking and is designated for applications requiring unique site and control change tracking, including certain automotive PPAP submissions. Both are Pb-free and RoHS compliant.
What is the thermal resistance from junction to case (RJC) for the MURHD560W1T4G?
The MURHD560W1T4G has a maximum thermal resistance of RJC = 2.5°C/W, measured from junction to the cathode tab (pins 2 and 4). This value assumes proper surface-mount assembly on a 1.5 mm FR4 board with a 700 mm² copper area. It enables efficient heat transfer to the PCB and supports up to 20 W of continuous power dissipation with ≤50°C temperature rise above case.
