Product details
Overview
5KP90HE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, rated for 5000 W peak pulse power (10/1000 μs), 90 V stand-off voltage (VWM), and clamping voltage of 146 V at 34.2 A peak pulse current. It is AEC-Q101 qualified and designed for robust overvoltage protection in automotive power supply rails and industrial DC bus lines.
For engineers reviewing the 5KP90HE3/54 datasheet, 5KP90HE3/54 pinout, 5KP90HE3/54 application, or 5KP90HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, P600 mechanical dimensions, clamping performance under 10/1000 μs surge, and direct alternatives with documented VBR, VC, and IPPM differences.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its breakdown range of 100–111 V (VBR at 5 mA). Its low incremental surge resistance ensures stable clamping during high-energy transients, while the glass-passivated P600 junction enables repeatable 5000 W surge handling at ≤0.01% duty cycle.
Designed for primary-side overvoltage suppression in switching power supplies, it replaces crowbar circuits by sustaining high peak currents (up to 34.2 A) long enough to allow upstream fusing or breaker tripping-without catastrophic failure-thanks to its 175 °C maximum junction temperature rating and 8.0 W steady-state power dissipation capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 90 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin in protected circuit. |
| VBR (min/max) | 100 V / 111 V at 5 mA - Confirmed breakdown threshold range; ensures reliable turn-on above system nominal voltage. |
| VC @ IPPM | 146 V at 34.2 A - Measured clamping voltage under 10/1000 μs surge; determines maximum voltage stress on downstream components. |
| PPPM | 5000 W - Peak pulse power rating per JEDEC standard; validates suitability for ISO 7637-2 Pulse 5a/b and IEC 61000-4-5 Level 4 surges. |
| IFSM | 600 A - Peak forward surge current (8.3 ms half-sine); supports high-energy fault clearing without bond wire fusing. |
| TJ max. | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments and high-ambient industrial enclosures. |
| Package | P600 - Axial-leaded, molded epoxy case (9.5 mm length, 5.4 mm diameter); UL 94 V-0 rated, RoHS-compliant, AEC-Q101 qualified. |
