Product details
Overview
5KP100A-E3/51 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 stand-off voltage (VWM), 111–123 V breakdown voltage (VBR) at 5.0 mA, 162 V clamping voltage (VC) at 30.9 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and used to protect MOSFETs and ICs in automotive power supply outputs.
For engineers reviewing the 5KP100A-E3/51 datasheet, 5KP100A-E3/51 pinout, 5KP100A-E3/51 application, or 5KP100A-E3/51 equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VCC, unidirectional polarity requirement, P600 thermal dissipation capability, and compliance with AEC-Q101 for automotive-grade reliability.
Technical Context
This TVS diode operates as a shunt-type overvoltage protector: under normal conditions it presents high impedance (>1 MΩ leakage at 100 V), then rapidly avalanches when reverse voltage exceeds VBR to clamp transients. Its P600 glass-passivated junction enables low incremental surge resistance and sub-nanosecond response time.
The device is rated for 5000 W peak pulse power (10/1000 μs waveform, 0.01% duty cycle), 8.0 W steady-state power on infinite heatsink at TL = 75 °C, and withstands 600 A non-repetitive forward surge (8.3 ms half-sine). Junction temperature range is –55 °C to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 111 V / 123 V at 5.0 mA - guaranteed avalanche initiation window for predictable turn-on |
| VC @ IPPM | 162 V at 30.9 A - clamped voltage during 5000 W transient, defining protection margin for downstream devices |
| PPPM | 5000 W (10/1000 μs) - energy-handling capacity sufficient for ISO 7637-2 Pulse 5a/b and IEC 61000-4-5 Level 4 surges |
| Polarity | Unidirectional - cathode-banded configuration; blocks forward conduction, clamps only reverse transients |
| Package | P600 - axial-leaded, epoxy-molded case rated UL 94 V-0, optimized for high-power PCB mounting with thermal relief |
| AEC-Q101 | Qualified - validated for automotive underhood applications including engine control units and body electronics |
Pinout & Package
P600 package: axial-leaded, cylindrical epoxy body (9.5 mm length × 5.6 mm diameter), matte tin-plated leads, cathode indicated by color band. Leads conform to J-STD-002/JESD 22-B102 solderability; RoHS-compliant per JEDEC JS709A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Cathode terminal | Connected to system ground or low-impedance return path; clamping occurs between cathode and anode when reverse voltage exceeds VBR |
| Cathode (non-banded end) | Anode terminal | Connected to protected line (e.g., 12 V rail); conducts surge current to ground during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power | Enables single-device protection against severe load-dump transients (e.g., ISO 7637-2 Pulse 5) without cascaded TVS stages |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected MOSFETs or DC-DC controllers while maintaining margin above VWM |
| AEC-Q101 qualification | Validates reliability for automotive powertrain and chassis modules requiring extended temperature and lifetime validation |
| P600 thermal robustness | Supports >8 W continuous dissipation with proper PCB copper area, enabling use in high-ambient under-hood environments |
| Uni-directional polarity | Prevents unintended forward conduction in DC-biased rails, eliminating risk of latch-up or power rail shorting |
Applications
| Automotive Load-Dump Protection | Industrial DC Power Rail Clamping |

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 PPPM (600 W), smaller SMB package, same VWM/VBR range | Not suitable for load-dump; limited to board-level ESD and low-energy transients | Select when space-constrained and surge energy <100 mJ; not a drop-in replacement for 5KP100A-E3/51 |
| 1.5KE100A | Same P600 package, lower PPPM (1500 W), higher VC (165 V), no AEC-Q101 qualification | Lacks automotive qualification; derated clamping performance at high temperatures | Acceptable for industrial non-automotive use where AEC-Q101 is not mandated and 1500 W suffices |
Compared with SMBJ100A and 1.5KE100A, the 5KP100A-E3/51 delivers 3.3× higher peak pulse power and certified automotive reliability-critical for protecting high-value ECUs and BCMs against full-load-dump events without layout or BOM revision.

FAQ
What is the clamping voltage of the 5KP100A-E3/51 under a 5000 W transient?
The 5KP100A-E3/51 clamps to a maximum of 162 V when subjected to its rated 30.9 A peak pulse current (IPPM), corresponding to a 5000 W transient with a 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 5KP100A-E3/51 suitable for bidirectional transient protection?
No, the 5KP100A-E3/51 is unidirectional only, with polarity marked by a cathode band. It clamps reverse-voltage transients but conducts forward current like a standard diode. For bidirectional protection, a separate 5KP100CA variant or back-to-back unidirectional configuration is required.
Does the 5KP100A-E3/51 require a heatsink for continuous operation?
The 5KP100A-E3/51 dissipates up to 8.0 W with an infinite heatsink at TL = 75 °C (per Fig. 5), but in typical PCB applications, thermal performance depends on copper area and airflow. No external heatsink is required for transient-only duty, but ≥2 in² of 2-oz copper pour is recommended for sustained surge repetition.
What does the "E3/51" suffix indicate in 5KP100A-E3/51?
The "E3" denotes RoHS-compliant, commercial-grade termination per JESD 201 Class 1A whisker testing; "/51" specifies the packaging option: 500-piece tape-and-reel on 7″ diameter reel (as defined in Vishay's ordering matrix, distinct from /54 which uses 13″ reels).
How does AEC-Q101 qualification impact the use of 5KP100A-E3/51 in automotive designs?
AEC-Q101 qualification confirms that the 5KP100A-E3/51 has passed accelerated stress tests-including temperature cycling, humidity bias HAST, and mechanical shock-required for automotive under-hood applications. This validates its suitability for ECU, BCM, and ADAS power domains where field reliability is mission-critical.
