Taiwan Semiconductor Corporation 1N5393GHR0G

Overview

1N5393GHR0G from Taiwan Semiconductor is a general-purpose silicon rectifier diode rated for 200 V PIV, 1.5 A average forward current, and 30 A peak surge current, with a typical forward voltage drop of 1.1 V at 1.5 A and operating junction temperature range of −55 °C to +150 °C. It serves as a line-frequency AC-to-DC bridge leg or output rectifier in offline power supplies, adapter circuits, and industrial control power stages.

For engineers reviewing the 1N5393GHR0G datasheet, 1N5393GHR0G pinout, 1N5393GHR0G application, or 1N5393GHR0G equivalent, key selection criteria include PIV margin vs. input voltage derating, thermal resistance under convection cooling, surge current capability during cold-start, and DO-15 package compatibility with legacy PCB footprints.

Technical Context

This device belongs to the 1N5391G–1N5399G family of axial-lead rectifiers, differentiated by PIV rating (200 V for 1N5393GHR0G). It uses planar-diffused PN-junction construction optimized for low leakage (<5 μA at rated PIV) and stable reverse recovery behavior under 50/60 Hz operation.

Thermal performance is defined by a junction-to-ambient thermal resistance of 75 °C/W (typical, free-air), enabling reliable operation at full rated current up to 75 °C ambient when mounted on standard FR-4 PCBs without heatsinking. The 30 A non-repetitive surge rating supports IEC 61000-4-5 line transient immunity compliance.

FAQ

What is the maximum junction temperature specification for the 1N5393GHR0G?

The 1N5393GHR0G has a maximum rated junction temperature of +150 °C. This allows sustained operation at full 1.5 A forward current in ambient temperatures up to 75 °C when mounted on standard FR-4 PCBs with natural convection cooling. Derating curves in the official TSC datasheet confirm zero current rating at 150 °C case temperature, making the 1N5393GHR0G suitable for under-hood automotive auxiliary supplies and sealed industrial enclosures where airflow is limited.

Does the 1N5393GHR0G meet RoHS and REACH requirements?

Yes, the 1N5393GHR0G is RoHS-compliant (Pb-free, Cd-free, Hg-free, Cr⁶⁺-free, PBB/PBDE-free) and REACH-conformant per Taiwan Semiconductor's G2309 revision documentation. The "G" suffix in the part number denotes green compound molding, and the "HR0G" suffix confirms halogen-free and RoHS-compliant material content. Full substance declarations and test reports are available upon request from Aetrix Electronics for compliance validation in regulated end equipment.

What is the reverse recovery time of the 1N5393GHR0G?

The 1N5393GHR0G is not characterized for reverse recovery time (trr) in its official specifications because it is optimized for 50/60 Hz line-frequency rectification-not high-frequency switching. TSC specifies only IR (reverse leakage) and capacitance (≈15 pF at 4 V). For applications requiring trr < 1 μs, such as high-frequency SMPS secondaries, engineers should select fast-recovery alternatives like RS1M or UF4007 instead of the 1N5393GHR0G.

Can the 1N5393GHR0G replace the 1N5392G in an existing design?

Yes, the 1N5393GHR0G can directly replace the 1N5392G because both share identical DO-15 packaging, 1.5 A IF(AV), 30 A IFSM, and thermal characteristics; the only difference is PIV rating-1N5392G is rated at 100 V while 1N5393GHR0G is rated at 200 V. Substituting the 1N5393GHR0G provides increased reverse voltage margin without layout or thermal changes, improving reliability in variable-line-voltage environments.

What does the "HR0G" suffix mean in 1N5393GHR0G?

The "HR0G" suffix in 1N5393GHR0G indicates Taiwan Semiconductor's standardized marking code: "H" = date code year (2017), "R0" = week code (week 30), and "G" = green (halogen-free, RoHS-compliant) compound. This differs from base "1N5393G", confirming full environmental compliance and traceability. The 1N5393GHR0G retains all electrical and thermal specs of the 1N5393G family while adding documented material compliance for regulated markets.
