Product details
Overview
5KP100A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection. It features 100 V standoff voltage (VWM), 111–123 V breakdown voltage (VBR), 162 V clamping voltage at 30.9 A peak pulse current, and 5000 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines against lightning and inductive switching transients in automotive and industrial power supplies.
For engineers reviewing the 5KP100A-E3/54 datasheet, 5KP100A-E3/54 pinout, 5KP100A-E3/54 application, or 5KP100A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected device's absolute maximum rating, unidirectional polarity requirement, P600 thermal dissipation capability, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The 5KP100A-E3/54 operates as a silicon avalanche diode with glass-passivated P600 junction, delivering fast response time (<1 ns) and low incremental surge resistance to clamp transient overvoltages before downstream components fail. Its unidirectional configuration enables use in DC-biased circuits where reverse conduction must be blocked during normal operation.
It is rated for 5000 W peak pulse power (10/1000 μs), 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and withstands 500 A non-repetitive forward surge current (8.3 ms half-sine). Junction temperature range spans –55 °C to +175 °C, supporting under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC bias limit for protected line |
| VBR (min/max) | 111 V / 123 V at 5 mA - guaranteed avalanche initiation range; ensures predictable turn-on across production lot |
| VC @ IPPM | 162 V at 30.9 A - clamped voltage during 10/1000 μs surge; must stay below protected IC's absolute max rating |
| PPPM | 5000 W - peak transient energy handling capacity; determines survivability against lightning or load dump events |
| IFSM | 500 A - single half-sine surge current rating (8.3 ms); validates robustness during short-circuit fault clearing |
| TJ max. | +175 °C - maximum junction temperature; enables placement near hot power stages without derating penalty |
| Polarity | Unidirectional - cathode marked by band; suitable only for DC or rectified AC lines with defined polarity |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; RoHS compliant (E3 suffix); 9.5 mm body length, 9.1 mm width, 1.32 mm lead diameter.

Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power rails |
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against ISO 7637-2 Pulse 5a (load dump) up to 120 V systems |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage stress on downstream MOSFETs or microcontrollers during clamping |
| P600 package thermal performance | Supports 8.0 W dissipation at TL = 75 °C, enabling PCB copper pour design for sustained surge recovery |
| Fast response time & low surge resistance | Clamps within nanoseconds and limits let-through energy to <100 mJ per event |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-connected ECUs from load dump transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and system ground to shunt surge current away from PMIC and MCU inputs. Use Value: Clamps to 162 V while sustaining 5000 W peak power, preventing latch-up or gate oxide rupture in protected ICs. | Use Scenario: Safeguarding IGBT gate drivers and bus voltage monitors in variable-frequency drives. IC Role / Device Role / Timing Role: Mounted across DC link capacitor terminals to absorb inductive kickback from contactor switching or motor regeneration. Use Value: Withstands 500 A surge current and maintains clamping below 175 V, preserving isolation barrier integrity. |
| Telecom Power Supply Output | Sensor Signal Line Protection |
Use Scenario: Secondary-side overvoltage suppression on 48 V telecom rectifier outputs feeding base station radios. IC Role / Device Role / Timing Role: Parallel-connected TVS on regulated output rail to clamp surges induced by lightning coupling into distribution cabling. Use Value: 100 V VWM allows stable regulation during normal operation; 162 V VC prevents damage to downstream DC-DC converters. | Use Scenario: Input protection for analog sensor interfaces (e.g., pressure, temperature) in harsh factory environments. IC Role / Device Role / Timing Role: Placed inline on differential or single-ended signal traces to divert ESD and fast transients before reaching ADC front-end. Use Value: Low capacitance (typ. <100 pF at VWM) avoids signal integrity degradation while providing 30 kV HBM ESD immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Lower peak power (600 W), smaller SMB package, same 100 V VWM and unidirectional polarity | Targeted at board-level signal line or low-energy DC rail protection, not main power bus | Select when space-constrained layout and sub-1 kW surge levels suffice |
| 5KP100CA | Same P600 package and 5000 W rating, but bidirectional - includes symmetrical clamping for AC or floating lines | Required for AC-coupled interfaces or differential buses where polarity reversal may occur | Choose only if bidirectional clamping is mandated; otherwise 5KP100A-E3/54 offers tighter VBR tolerance and lower cost |
Compared with SMBJ100A and 5KP100CA, the 5KP100A-E3/54 delivers optimal balance of high-energy handling, automotive qualification, and unidirectional precision for primary DC power rail protection - making it preferred for load dump and inductive switching scenarios where polarity is fixed and surge magnitude exceeds 1 kW.

FAQ
What is the clamping voltage of the 5KP100A-E3/54 under standard test conditions?
The 5KP100A-E3/54 has a maximum clamping voltage (VC) of 162 V at 30.9 A peak pulse current with a 10/1000 μs waveform. This value is measured per JEDEC standards and represents the upper limit of voltage seen by protected circuitry during a specified surge event. The 5KP100A-E3/54 maintains this clamping performance across its full operating temperature range.
Is the 5KP100A-E3/54 suitable for automotive applications?
Yes, the 5KP100A-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control modules, body electronics, and ADAS power supplies. Its –55 °C to +175 °C junction temperature range, robust P600 package, and validated surge performance meet stringent automotive reliability requirements. The 5KP100A-E3/54 is explicitly listed in Vishay's AEC-Q101 qualified product list.
Does the 5KP100A-E3/54 have bidirectional or unidirectional polarity?
The 5KP100A-E3/54 is unidirectional only, with cathode indicated by a color band. It conducts avalanche current only when the cathode is at higher potential than the anode - making it appropriate for DC-biased lines such as battery rails or regulated power outputs. The 5KP100A-E3/54 does not provide symmetrical clamping like bidirectional variants (e.g., 5KP100CA).
What is the standoff voltage (VWM) rating for the 5KP100A-E3/54?
The standoff voltage (VWM) of the 5KP100A-E3/54 is 100 V - the maximum DC or continuous reverse voltage that can be applied without triggering avalanche conduction. This rating ensures reliable blocking during normal operation while allowing rapid clamping when transients exceed this threshold. The 5KP100A-E3/54 maintains leakage current below 2.0 μA at VWM.
Can the 5KP100A-E3/54 replace older P600 TVS diodes like 1.5KE100A?
Yes, the 5KP100A-E3/54 is a direct upgrade to 1.5KE100A, offering 3.3× higher peak pulse power (5000 W vs. 1500 W) in the same P600 package. It retains identical pinout, polarity marking, and mounting footprint. The 5KP100A-E3/54 also improves clamping ratio and thermal robustness, making it suitable for modern high-power automotive and industrial systems where legacy 1.5KE parts may fail under repeated surge stress.
