MUR460G

MUR460G is a high-speed ultrafast rectifier diode in the MUR family. The “G” suffix typically indicates RoHS-compliant (lead-free) packaging. It is used for fast rectification in switching power supplies, flyback diodes, and freewheel paths in SMPS.
Key specs (typical):
- VRRM: 600 V
- IF(AV): 4 A
- IFSM: up to ~40–60 A
- trr: tens of nanoseconds (very fast recovery)
Features:
- Fast reverse recovery to minimize switching losses
- Suitable for high-frequency, moderate-power applications
- Available in multiple packages (surface-mount and through-hole) depending on vendor
Applications:
- Flyback/DC-DC converters, SMPS rectification, motor-drive snubbers, power inverters
Note: Always check the specific datasheet for exact ratings, packaging, and thermal data for your MUR460G variant.

Direct equivalents are 4 A, 600 V ultra‑fast/fast‑recovery rectifiers with similar Vf, trr/Qrr and package. Common cross‑references: MUR460 (other manufacturers/variants), STMicro STTH4R06, and equivalent parts from Vishay, Diodes Inc. or ON Semiconductor. When substituting, match voltage (600 V), average/peak current (≈4 A), forward drop, reverse recovery and package.

MUR460G is an ultrafast recovery rectifier diode. Key features:
- VRRM: 600 V
- IF(AV): 4 A
- Ultrahigh-speed reverse-recovery (trr typically ~55 ns)
- Forward voltage drop: ~1.1–1.3 V at 4 A
- High peak surge current (IFSM in tens of amperes)
- Pb-free / RoHS-compliant (G suffix)
- Suitable for switch-mode power supplies and fast rectification applications
Note: packaging varies by variant; consult the datasheet for exact package and thermal details.

Pin count: 2 pins (anode and cathode).
Function: The MUR460G is an ultrafast recovery power rectifier diode used for unidirectional current conduction in high‑speed switching and power‑rectification circuits (e.g., SMPS, freewheeling, snubbers). It offers fast reverse‑recovery characteristics and is rated for high voltage (typically 600 V) and multi‑ampere forward current.

The MUR460G part is produced by multiple semiconductor suppliers; a common manufacturer is Micro Commercial Components (MCC). MCC is a semiconductor company that designs and manufactures discrete power components—primarily diodes, rectifiers, transistors and related passive and power-management parts—serving electronics manufacturers and distributors.

Applications of MUR460G:
- High-speed rectification in switch-mode power supplies (SMPS) and DC-DC converters
- Front-end rectification in AC-DC adapters and telecom power supplies
- Freewheeling/rectification in flyback, boost, and buck-boost converter topologies
- Power factor correction (PFC) circuits and snubber networks
- High-frequency inverters and motor-drive topologies needing fast recovery diodes
Note: MUR460G is a 600V, 4A ultrafast recovery diode suitable for these applications.
