MUR190A A0G

Single Diodes Overview

The MUR190A A0G is a high-efficiency silicon rectifier diode from the MUR160–MUR190 series manufactured by Taiwan Semiconductor. It features a single die configuration in a DO-204AC (DO-15) package with an average forward current of 1 A and a repetitive peak reverse voltage of 900 V. The device supports a maximum junction temperature of 175°C and exhibits a typical reverse recovery time of 75 ns at 25°C. Electrical specifications include a maximum forward voltage of 1.70 V at 1 A and a maximum reverse current of 150 µA at 125°C.

Single Diodes Feature Summary

• High efficiency operation characterized by low forward voltage drop and fast recovery time
• Capable of operating at elevated junction temperatures up to 175°C
• Constructed with pure tin plated leads that are solderable per J-STD-002 standards

Single Diodes Applications

• DC to DC converter circuits
• Switching mode power supplies and inverters
• Freewheeling applications in electronic systems

Single Diodes Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm packaging details. The A0G suffix indicates availability in an ammo box format containing 1,500 units per reel. Confirm RoHS compliance and halogen-free status according to IEC 61249-2-21 requirements before finalizing procurement specifications for your project.

Single Diodes Selection Notes

Select this component when designing circuits requiring a 900V blocking capability with a 1A continuous current rating. Ensure the thermal management design accommodates the specified junction-to-ambient thermal resistance. Consider the 75 ns reverse recovery time suitability for the target switching frequency and verify that the DO-204AC through-hole package aligns with the PCB layout constraints.

Single Diodes Part Context

This part belongs to the MUR160–MUR190 series of high-efficient rectifiers produced by Taiwan Semiconductor. The series covers voltage ratings from 600V to 900V within the same physical footprint. The MUR190 variant specifically provides the highest voltage rating in this lineup while maintaining identical current handling and package dimensions as its lower-voltage counterparts.

Single Diodes Replacement Considerations

Direct substitutes within the same series include the MUR160 and MUR180 variants if lower voltage ratings are acceptable. Verify that any replacement maintains the DO-204AC package and meets the required 1A forward current specification.
