Product details

Overview

MUR860H from Taiwan Semiconductor is an AEC-Q101-qualified ultra-fast recovery rectifier diode in TO-220AC package, rated for 8A average forward current and 600V repetitive peak reverse voltage, with 50ns reverse recovery time and 1.700V max forward voltage at 8A/25°C - used in automotive-grade DC-DC converters and switching inverters.

For engineers reviewing the MUR860H datasheet, MUR860H pinout, MUR860H application, or MUR860H equivalent, key selection criteria include its 600V V_RRM, AEC-Q101 qualification, 2°C/W junction-to-case thermal resistance, 100A surge rating, and TO-220AC single-die configuration for high-reliability power conversion stages.

Technical Context

The MUR860H employs a glass-passivated silicon junction optimized for ultra-fast switching (t_rr = 50 ns), minimizing switching losses in high-frequency SMPS topologies. Its 600V blocking capability and 100A non-repetitive surge current support robust operation under transient overloads.

Thermally, the device delivers 2°C/W R_θJC in TO-220AC package, enabling efficient heat transfer to heatsinks in automotive and industrial power supplies. The matte tin-plated leads comply with J-STD-002 solderability standards.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports primary-side rectification in 400–600V bus systems without derating
I_F	8 A continuous - sustains full-load conduction in compact 100–300W DC-DC modules
t_rr	50 ns - enables operation up to ~500 kHz switching frequency with low recovery loss
V_F (max)	1.700 V @ 8A/25°C - limits conduction loss to ≤13.6 W at full load, critical for thermal design
R_θJC	2 °C/W - allows ≥40W power dissipation with 80°C case temperature rise using standard heatsink
I_FSM	100 A (8.3 ms) - withstands inrush and fault currents in automotive cold-crank and load-dump scenarios

Pinout & Package

Package: TO-220AC - single-die, 3-lead through-hole package with isolated tab (cathode-connected tab), matte tin-plated leads, UL 94V-0 molding compound, and polarity marked on device body.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Input current terminal	Connected to AC or switched node; must handle full I_F and I_FSM with low-inductance layout
Cathode	Output current terminal	Internally bonded to metal tab; electrically common with mounting surface - requires insulating washer if tab is not grounded
Tab (Cathode)	Thermal & electrical cathode path	Serves dual role: primary heat conduction path and cathode return - no separate cathode lead; tab must be electrically referenced per circuit topology

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH8R06DJF	600V V_RRM, 8A I_F, t_rr = 35 ns, TO-220AC, but not AEC-Q101 qualified	Preferred for industrial SMPS where automotive qualification is unnecessary	Select when lower t_rr is prioritized over automotive compliance
IXYS MUR860E	Identical ratings (600V/8A/50ns), same TO-220AC package, AEC-Q101 qualified, but higher V_F (1.75V max)	Drop-in alternative with identical footprint and qualification, minor efficiency trade-off	Choose when second-source assurance is required and 50mV V_F increase is acceptable

Compared with STTH8R06DJF, MUR860H adds AEC-Q101 validation for automotive use without sacrificing speed; versus IXYS MUR860E, it offers 50mV lower V_F, improving conduction efficiency in thermally constrained designs.

FAQ

What is the maximum junction temperature rating for the MUR860H?

The MUR860H has a maximum junction temperature (T_J) of +175°C, verified per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial enclosures. Thermal design must maintain T_J ≤175°C using the specified R_θJC = 2°C/W and appropriate heatsinking. Exceeding this limit risks permanent degradation of the glass-passivated junction.

Is the MUR860H pin-compatible with standard TO-220AC rectifiers?

Yes, the MUR860H uses the industry-standard TO-220AC outline with Anode–Cathode–Tab pinout and 2.54 mm lead spacing. Its cathode is internally connected to the metal tab, matching conventional TO-220AC rectifier layout. No PCB redesign is needed when replacing legacy TO-220AC ultra-fast diodes - provided thermal and electrical constraints (e.g., V_RRM, t_rr) are verified for the target application.

Does the MUR860H meet automotive qualification standards?

Yes, the "H" suffix in MUR860H explicitly denotes AEC-Q101 qualification. Taiwan Semiconductor subjects the MUR860H to full AEC-Q101 stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST). This makes MUR860H suitable for automotive powertrain, body control, and ADAS subsystems requiring certified reliability.

What is the reverse recovery time (t_rr) of the MUR860H and how is it measured?

The MUR860H has a typical reverse recovery time (t_rr) of 50 ns, measured under conditions: I_F = 0.5 A, I_R = 1.0 A, I_RR = 0.25 A, per JEDEC JESD24-11. This value is confirmed across the full temperature range and ensures minimal switching loss in high-frequency converters. The 50 ns t_rr is consistent for all MUR8xH variants rated ≥400V.

How does the forward voltage (V_F) of the MUR860H compare to lower-voltage variants in the same family?

At I_F = 8 A and T_J = 25°C, the MUR860H has a maximum V_F of 1.700 V - higher than MUR820 (0.975 V) and MUR840 (1.300 V) due to increased doping gradient for 600V blocking. This trade-off is inherent in ultra-fast rectifier design: higher V_RRM requires deeper depletion layers, raising on-state resistance. System-level efficiency analysis must account for this V_F increase when selecting MUR860H over lower-voltage variants.
