Diodes Incorporated MUR160

Overview

MUR160 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-designed for high-frequency switching power supplies, AC/DC adapters, and flyback converter output stages.

For engineers reviewing the MUR160 datasheet, MUR160 pinout, MUR160 application, or MUR160 equivalent, key selection criteria include its 600V VRRM rating, low trr for reduced switching loss, thermal resistance of 72 K/W, RoHS-compliant bright tin terminals, and compatibility with automated assembly processes.

Technical Context

The MUR160 employs glass-passivated silicon die construction to ensure stable junction performance under repetitive surge stress and elevated temperature operation up to +175°C. Its super-fast recovery (50 ns typical at IF = 0.5A, IR = 1.0A, Irr = 0.25A) enables efficient operation in 50–500 kHz SMPS topologies.

Designed for single-phase, half-wave rectification with resistive or inductive loads at 60 Hz, it requires 20% current derating for capacitive loads. The device exhibits 45 pF junction capacitance and maintains 150 µA peak reverse current at 150°C and rated DC blocking voltage.

Key Specifications

Pinout & Package

Package: DO-41 axial leaded plastic case (UL 94V-0), 0.35 g mass, cathode band marking (R160), bright tin-plated leads solderable per MIL-STD-202 Method 208.

Equivalent & Alternatives

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

Compared with STTH1R06 and ES1J, the MUR160 uniquely balances 50 ns trr, 1.25 V forward drop, axial DO-41 form factor, and 35A surge rating-making it optimal for cost-sensitive, thermally moderate, through-hole SMPS output rectification where footprint and assembly compatibility are critical.

FAQ

What is the maximum junction temperature for continuous operation of MUR160?

The MUR160 has an operating junction temperature range of –65°C to +175°C. For reliable continuous operation at 1.0A average forward current, the terminal temperature must be maintained at ≤120°C per the derating curve in Figure 1. Exceeding this requires thermal design mitigation such as increased copper area or airflow.

Can MUR160 replace a standard 1N4007 in a 60 Hz linear power supply?

No-while both are DO-41 rectifiers, the MUR160's super-fast 50 ns recovery is unnecessary and offers no benefit at 60 Hz. Its 1.25 V forward drop is higher than the 1N4007's ~1.1 V, increasing conduction loss. Use only where high-frequency switching or low trr is required.

Is MUR160 suitable for use in a synchronous rectification circuit?

No-MUR160 is a unidirectional PN junction diode, not a MOSFET-based synchronous rectifier. It cannot be actively controlled or gated. It serves as a passive rectifier only; synchronous designs require external MOSFETs and gate drivers.

Does MUR160 meet lead-free soldering requirements for RoHS compliance?

Yes-MUR160 features bright tin-plated leads compliant with RoHS Directive 2011/65/EU, including exemptions for high-temperature soldering and glass passivation (Annexes 5 and 7). It withstands standard lead-free reflow profiles up to 260°C peak temperature per J-STD-020C.
