Product details
Overview
MUR160-T from Diodes Incorporated is a 1.0A, 600V super-fast recovery rectifier diode in DO-41 package, featuring 50 ns reverse recovery time (trr), 1.25 V forward voltage at 1.0A/25°C, and 35A non-repetitive surge capability - used in high-frequency switch-mode power supply output stages and DC-DC converter freewheeling paths.
For engineers reviewing the MUR160-T datasheet, MUR160-T pinout, MUR160-T application, or MUR160-T equivalent, key selection criteria include peak reverse voltage rating (600 V), ultra-fast trr (50 ns), thermal resistance (72 K/W), junction temperature range (–65°C to +175°C), and RoHS-compliant tin-plated terminals for lead-free reflow compatibility.
Technical Context
This super-fast rectifier uses glass-passivated silicon die construction to achieve low Qrr and tight trr distribution. Its 600 V VRRM rating supports universal-input offline SMPS designs, while the 50 ns trr (measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A) enables operation up to 100 kHz without excessive switching loss.
The device exhibits 1.05 V VFM at 1.0A and 150°C, confirming stable conduction under elevated thermal stress. Its 72 K/W RJA and –65°C to +175°C Tj range support high-density PCB layouts with minimal heatsinking in industrial and telecom power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - blocks full-wave rectified 424 V RMS input without breakdown in offline AC-DC front-ends |
| IO | 1.0 A @ TT = 120°C - continuous DC output current rating with standard PCB copper area cooling |
| trr | 50 ns - enables efficient high-frequency switching in PFC and LLC resonant converters |
| VFM | 1.25 V @ 1.0A, 25°C - low conduction loss improves efficiency in 12–48 V secondary-side rectification |
| IFSM | 35 A - withstands inrush surges during cold-start of 100 W+ power supplies |
| RJA | 72 K/W - defines thermal rise per watt dissipated on standard FR-4 with 1 sq-in copper pad |
| Tj Range | –65°C to +175°C - supports operation in automotive under-hood and industrial motor drive environments |
Pinout & Package
DO-41 axial-leaded plastic package with cathode band marking; body diameter 4.06–5.21 mm, length 25.40 mm, lead diameter 0.71–0.864 mm, lead spacing 2.00–2.72 mm; weight ≈ 0.35 g; UL 94V-0 rated mold compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry point | Connected to transformer secondary or switching node; must handle 1.0 A DC and 35 A transient |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to output filter capacitor or ground return; sustains 600 V reverse bias continuously |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Eliminates surface leakage paths, ensuring stable IRM < 5 µA at 25°C and < 150 µA at 150°C |
| Super-fast trr = 50 ns | Reduces switching loss by >40% vs. standard fast rectifiers (e.g., 1N5622) in 50–100 kHz converters |
| Low VFM = 1.25 V | Lowers conduction loss to ~1.25 W at 1.0 A, easing thermal design in compact adapters |
| RoHS-compliant tin finish | Enables lead-free reflow soldering at 260°C peak without dewetting or intermetallic degradation |
| DO-41 mechanical standardization | Supports automated axial insertion and wave soldering with industry-standard tape-and-reel (5K/reel) packaging |
Applications
| AC-DC Adapter Output Stage | DC-DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Secondary-side rectification in 12–24 V, 30–60 W wall adapters with 65–100 kHz flyback topology. IC Role / Device Role / Timing Role: Unidirectional current path that conducts during transformer reset phase and blocks reverse voltage during primary switch ON time. Use Value: 50 ns trr minimizes reverse recovery charge (Qrr), reducing EMI and improving efficiency by 1.2–1.8% over standard fast diodes. | Use Scenario: Freewheeling path in synchronous-buck-derived isolated DC-DC modules for FPGA power rails. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when high-side MOSFET is OFF, sustaining inductor current continuity. Use Value: 1.25 V VFM at 1.0 A limits conduction loss to ≤1.25 W, enabling natural convection cooling in space-constrained modules. |
| Industrial Motor Drive Snubber Network | Telecom Rectifier Module Input Stage |
Use Scenario: Snubber clamp diode across IGBT gate drivers in 3-phase inverter control boards operating at 10–20 kHz PWM. IC Role / Device Role / Timing Role: Rapidly clamps voltage spikes during IGBT turn-off by absorbing inductive energy before it reaches destructive levels. Use Value: 35 A IFSM and 600 V VRRM tolerate repetitive 600 V transients with < 100 ns rise time without avalanche degradation. | Use Scenario: Input bridge rectifier in 48 V telecom rectifier modules accepting –57 V to –60 V DC input with hot-swap capability. IC Role / Device Role / Timing Role: Converts negative-polarity DC input to positive bus for downstream DC-DC conversion, handling reverse polarity fault conditions. Use Value: –65°C to +175°C Tj range ensures reliable operation during extended burn-in at 85°C ambient and load cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same 600 V VRRM and 1.0 A IO, but trr = 65 ns (vs. 50 ns); VFM = 1.30 V @ 1.0A/25°C | Slightly higher switching loss in >80 kHz designs; acceptable in 40–60 kHz industrial PSUs | Select if STMicroelectronics supply chain preference applies and trr margin ≥15 ns is acceptable |
| ES1J | Lower 600 V VRRM but only 1.0 A IO and trr = 35 ns; VFM = 1.7 V @ 1.0A/25°C | Better trr but higher conduction loss; unsuitable for thermally constrained 12 V outputs | Prefer only where ultra-low Qrr dominates over thermal budget, e.g., low-duty-cycle pulse circuits |
Compared with STTH1R06 and ES1J, MUR160-T delivers optimal balance of ultra-fast recovery (50 ns), low forward drop (1.25 V), and robust surge rating (35 A), making it preferred for high-efficiency, high-reliability 60–100 kHz power conversion where both switching and conduction losses must be minimized.

FAQ
What is the maximum junction temperature for MUR160-T during continuous operation?
The MUR160-T has a specified operating junction temperature range of –65°C to +175°C. Under continuous 1.0 A DC load at 25°C ambient with standard PCB cooling, junction temperature remains below 120°C. Derating is required above 120°C terminal temperature per Figure 1 in the datasheet.
Is MUR160-T compatible with lead-free reflow soldering processes?
Yes. MUR160-T features bright tin-plated leads compliant with RoHS Directive 2011/65/EU and qualified for lead-free reflow per J-STD-020C. Its terminals withstand peak temperatures up to 260°C for 30 seconds without solderability degradation or package delamination.
How does the 50 ns reverse recovery time impact EMI performance?
A 50 ns trr reduces reverse recovery charge (Qrr) to ~15 nC, minimizing high-frequency ringing and dv/dt-induced noise during turn-off. This directly lowers conducted EMI in the 150 kHz–30 MHz band, easing compliance with CISPR-22 Class B limits without additional snubbers in well-layouted PCBs.
Can MUR160-T replace MUR140-T in existing designs?
Yes, with design verification. MUR160-T shares identical DO-41 package, pinout, and thermal characteristics with MUR140-T but offers higher 600 V VRRM (vs. 400 V). It can be substituted where increased reverse voltage margin is needed, provided layout clearance and insulation meet 600 V requirements.
