Product details
Overview
MUR160H from Taiwan Semiconductor is an AEC-Q101-qualified, 1 A, 600 V high-efficiency ultrafast recovery rectifier in DO-204AC (DO-15) package, featuring 1.25 V max forward voltage at 1 A/25°C, 50 ns max reverse recovery time, and 175°C maximum junction temperature-used in automotive DC-DC converters and switching-mode power supplies.
For engineers reviewing the MUR160H datasheet, MUR160H pinout, MUR160H application, or MUR160H equivalent, key selection criteria include its AEC-Q101 qualification, 600 V repetitive peak reverse voltage, ultrafast 50 ns trr, low VF performance across temperature, and DO-15 mechanical compatibility for space-constrained board layouts.
Technical Context
This discrete silicon planar epitaxial diode uses a single-die construction optimized for high-frequency switching operation. Its ultrafast recovery (trr ≤ 50 ns) and low forward voltage (VF ≤ 1.25 V @ 1 A, 25°C) minimize conduction and switching losses in hard-switched topologies.
The device supports continuous operation up to TJ = 175°C and exhibits low junction capacitance (CJ = 27 pF @ 1 MHz, 4 V), enabling stable performance in high-speed flyback and boost converter freewheeling paths where reverse recovery behavior directly impacts EMI and efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Rated Forward Current) | 1 A continuous - supports compact 1A-level power stage designs without forced cooling |
| VRRM (Repetitive Peak Reverse Voltage) | 600 V - suitable for 400 V DC bus applications with 50% safety margin |
| trr (Reverse Recovery Time) | ≤ 50 ns - reduces switching loss and ringing in 100–500 kHz SMPS |
| VF (Forward Voltage) | ≤ 1.25 V @ 1 A, 25°C - lowers conduction loss vs. standard fast rectifiers |
| TJ max (Max Junction Temperature) | 175°C - enables operation in under-hood automotive environments |
| RθJA (Junction-to-Ambient Thermal Resistance) | 50°C/W - defines thermal derating curve for PCB pad layout and copper area requirements |
| IR (Reverse Leakage Current) | ≤ 5 µA @ 25°C, ≤ 150 µA @ 125°C - ensures low standby loss in high-impedance bias networks |
Pinout & Package
Package: DO-204AC (DO-15), axial lead, epoxy-molded, cathode indicated by band. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Current entry point during forward conduction | Connected to lower-potential node (e.g., switch node in boost/flyback) |
| Cathode (Lead 2, banded end) | Current exit point during forward conduction; reverse-blocking terminal | Connected to output rail or positive bus; must withstand full VRRM during off-state |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per stress test conditions |
| Ultrafast recovery (trr ≤ 50 ns) | Reduces turn-off loss and dv/dt-induced gate oscillation in MOSFET-based converters |
| Low VF (≤ 1.25 V @ 1 A) | Improves system efficiency by ~0.3–0.5% in 12–48 V output DC-DC stages |
| 175°C maximum junction temperature | Enables placement near hot components (e.g., inductors, MOSFETs) without thermal throttling |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU Directive 2011/65/EU for green manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same IF (1 A), VRRM (600 V), DO-15 package; trr = 50 ns typical but not AEC-Q101 qualified | Lacks automotive qualification; limited to industrial/commercial use only | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs |
| ES1J | Lower VRRM (600 V), same package; trr = 35 ns typ but VF = 1.7 V max - higher conduction loss | Better speed but worse thermal performance due to higher VF and lower TJ rating (150°C) | Prefer for speed-critical non-automotive designs where layout allows extra thermal margin |
Compared with STTH1R06 and ES1J, the MUR160H uniquely combines AEC-Q101 qualification, 175°C TJ rating, and balanced VF/trr trade-off-making it the only choice for under-hood automotive power conversion where reliability and thermal headroom are non-negotiable.

FAQ
What is the AEC-Q101 qualification status of the MUR160H?
The MUR160H is fully AEC-Q101 qualified per Version L2107 documentation, covering stress tests including HTGB, HTRB, temperature cycling, and ESD. This certification confirms its suitability for automotive powertrain and chassis applications where reliability under thermal and electrical stress is critical. The MUR160H qualification applies specifically to the "H" suffix variant-not the base MUR160.
What is the maximum reverse recovery time (trr) specification for MUR160H?
The MUR160H has a maximum reverse recovery time of 50 ns under specified test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A). This value is confirmed in the Electrical Specifications table on page 2 of the official Taiwan Semiconductor datasheet (L2107). The MUR160H's trr remains stable across its rated temperature range, supporting consistent switching performance in high-frequency converters.
Does MUR160H have the same forward voltage as MUR190?
No. The MUR160H has a maximum forward voltage of 1.25 V at 1 A and 25°C, while the MUR190 is rated at 1.70 V under identical conditions. This difference reflects the higher voltage-blocking structure in MUR190, which increases series resistance. For designs prioritizing low conduction loss at 600 V rating, the MUR160H delivers superior VF performance versus the MUR190.
What packaging options are available for MUR160H?
The MUR160H is supplied in DO-204AC (DO-15) package with two standard packing formats: 3,500 units per tape-and-reel (ordering code MUR160H) and 1,500 units per ammo box (ordering code MUR160HA0G). Both variants retain identical electrical and thermal specifications; the choice depends on SMT line compatibility and inventory management requirements for the MUR160H.
Is MUR160H compatible with lead-free reflow soldering processes?
Yes. The MUR160H features pure tin-plated leads compliant with J-STD-002 for solderability, and its epoxy molding compound meets UL 94V-0 flammability rating. It is qualified for standard lead-free reflow profiles (peak temperature ≤ 260°C, 60 sec max), with no special pre-bake required. The MUR160H's thermal robustness supports repeated reflow cycles without parameter shift or delamination.
