Product details
Overview
5KP90-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on DC power rails and signal lines. It features 5000 W peak pulse power (10/1000 µs), 90 V stand-off voltage (VWM), 100–111 V breakdown voltage (VBR), and clamps transients to ≤146 V at 34.2 A peak pulse current - deployed in automotive power supply outputs and industrial sensor interfaces.
For engineers reviewing the 5KP90-E3/54 datasheet, 5KP90-E3/54 pinout, 5KP90-E3/54 application, or 5KP90-E3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and compatibility with 13" tape-and-reel delivery for automated SMT assembly.
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protection device, triggered when reverse voltage exceeds its 100–111 V breakdown range. Its glass-passivated P600 junction enables fast response (<1 ns) and stable clamping under repetitive 10/1000 µs surges at 0.01% duty cycle.
It sustains 5000 W peak pulse power without degradation, dissipates up to 8.0 W continuously on an infinite heatsink at 75 °C lead temperature, and withstands 600 A non-repetitive forward surge (8.3 ms half-sine). The cathode is marked by a color band; terminals are matte tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 90 V - maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 12 V/24 V/48 V systems. |
| VBR @ IT = 5.0 mA | 100–111 V - verified breakdown threshold ensuring precise triggering above nominal system voltage. |
| VC @ IPPM = 34.2 A | ≤146 V - clamped voltage during full-rated 5000 W surge; limits downstream IC stress in power supply output stages. |
| PPPM | 5000 W - peak pulse power handling per JEDEC-standard 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 compliance. |
| IFSM | 600 A - 8.3 ms single half-sine surge rating; enables robust crowbar replacement in switching power supplies. |
| TJ max | 175 °C - extended thermal capability allows operation in under-hood automotive environments and enclosed industrial enclosures. |
| Leakage @ VWM | ≤2.0 µA - ultra-low reverse leakage preserves efficiency in battery-backed or low-power sensor circuits. |
Pinout & Package
5KP90-E3/54 uses the axial-lead P600 package: molded epoxy body with glass-passivated junction, UL 94 V-0 rated compound, and matte tin-plated leads. Cathode is marked by a color band on the body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point during forward conduction; connected to lower-potential side of protected circuit. | Enables standard placement across DC rails - anode to ground or return path for unidirectional clamping. |
| Cathode (banded end) | Current exit point during reverse-biased clamping; connected to higher-potential line (e.g., +VOUT). | Ensures correct polarity for transient suppression: cathode to protected line, anode to reference (ground or return). |
Key Features

Applications
| Automotive Power Supply Output | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V DC-DC converter outputs in engine control modules against load dump and alternator ripple. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed between output rail and chassis ground to shunt surge energy before it reaches downstream regulators and CAN transceivers. Use Value: Clamps transients to ≤146 V while sustaining 5000 W pulses - prevents latch-up and gate oxide damage in automotive-grade PMICs and microcontrollers. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) in factory automation PLCs from ESD and relay coil flyback. IC Role / Device Role / Timing Role: Unidirectional TVS installed across differential signal pairs or single-ended sensor supply lines to limit voltage excursions during field wiring faults. Use Value: 2.0 µA leakage at 90 V preserves signal integrity in µA-level sensor bias networks; fast response avoids data corruption during 8 kV contact ESD events. |
| Telecom DC Power Feeds | Switching Power Supply Crowbar Replacement |
Use Scenario: Safeguarding -48 V telecom rectifier outputs against induced surges from nearby lightning strikes or AC mains coupling. IC Role / Device Role / Timing Role: Primary overvoltage clamp on the DC distribution bus, coordinated with upstream fuses to allow controlled fault clearing. Use Value: 600 A 8.3 ms surge rating enables coordination with 30–60 A slow-blow fuses - permits fuse blow before TVS thermal runaway. |
Use Scenario: Replacing SCR-based crowbar circuits in 100–500 W AC/DC adapters to reduce component count and improve reset reliability. IC Role / Device Role / Timing Role: Standby-mode TVS that conducts only during overvoltage, eliminating need for separate trigger circuitry and latching logic. Use Value: Eliminates crowbar complexity while maintaining <146 V clamping - enables automatic recovery after transient clearance without manual reset. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90A | Lower peak power (600 W), smaller SMB package, same 90 V VWM, but limited to 30 A IPPM. | Suitable for board-level signal line protection; insufficient for power rail crowbar replacement. | Select SMBJ90A only for space-constrained PCBs where surge energy is ≤600 W - not a drop-in replacement for 5KP90-E3/54 in power supply outputs. |
| 1.5KE91A | Same 91 V VWM, 1500 W PPPM, DO-201 package, higher leakage (5.0 µA), no AEC-Q101 qualification. | Acceptable for commercial-grade industrial controls but excluded from automotive under-hood use. | Choose 1.5KE91A for cost-sensitive non-automotive applications requiring basic 90 V clamping - verify thermal derating at elevated ambient temperatures. |
Compared with SMBJ90A and 1.5KE91A, the 5KP90-E3/54 delivers 3.3× higher surge power than SMBJ90A and 3.3× higher than 1.5KE91A, maintains AEC-Q101 qualification, and supports direct integration into high-current power rails without external heatsinking - making it uniquely suited for automotive and industrial primary-side protection.

FAQ
What is the breakdown voltage range of the 5KP90-E3/54?
The 5KP90-E3/54 has a guaranteed breakdown voltage (VBR) range of 100 V to 111 V at 5.0 mA test current, measured per JEDEC standards. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage detection in 90 V nominal systems. The 5KP90-E3/54's VBR is validated during 100% production testing.
Is the 5KP90-E3/54 suitable for automotive applications?
Yes, the 5KP90-E3/54 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C junction temperature - meeting requirements for under-hood engine control units, body electronics, and ADAS power domains. Its P600 package provides mechanical robustness and thermal mass needed for automotive thermal cycling, and the E3 suffix confirms JESD 201 Class 1A whisker resistance.
What is the clamping voltage of the 5KP90-E3/54 at its rated peak pulse current?
At its rated peak pulse current of 34.2 A (corresponding to 5000 W with a 10/1000 µs waveform), the 5KP90-E3/54 clamps to a maximum of 146 V. This value is specified in the Vishay datasheet as VC and represents the upper limit of voltage seen by protected circuitry during worst-case surge events - critical for validating downstream component voltage ratings.
Does the 5KP90-E3/54 have bidirectional polarity?
No, the 5KP90-E3/54 is unidirectional only, with cathode identified by a color band. It conducts in reverse bias during overvoltage events and blocks forward current up to 3.5 V at 100 A. For AC line or bidirectional signal protection, a separate bidirectional variant (e.g., 5KP90CA) would be required - the 5KP90-E3/54 is not rated for symmetrical clamping.
What packaging format is used for the 5KP90-E3/54?
The 5KP90-E3/54 ships in 13" diameter paper tape and reel with a base quantity of 800 units per reel (package code /54). The P600 axial-leaded package features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards, supporting both wave and selective soldering processes in high-volume manufacturing.
