Product details
Overview
5KP11AHE3_A/C from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on power rails and signal lines. It features 11.0 V stand-off voltage (VWM), 12.2–13.5 V breakdown voltage (VBR) at 5 mA, 5000 W peak pulse power (10/1000 μs), 275 A peak pulse current (IPPM), and clamps to ≤18.2 V at rated surge. It is AEC-Q101 qualified and used in automotive power supply output protection.
For engineers reviewing the 5KP11AHE3_A/C datasheet, 5KP11AHE3_A/C pinout, 5KP11AHE3_A/C application, or 5KP11AHE3_A/C equivalent, key selection criteria include unidirectional polarity, P600 package thermal performance, clamping voltage margin vs. protected IC VDD, AEC-Q101 qualification status, and 10/1000 μs waveform compliance for ISO 7637-2 and IEC 61000-4-5 surge immunity.
Technical Context
This TVS operates as a voltage-clamping device triggered by reverse-biased avalanche breakdown above its VBR threshold. Its P600 glass-passivated junction enables robust 5000 W surge handling with low incremental surge resistance and fast response time (<1 ns), critical for protecting downstream MOSFETs and DC-DC controllers from inductive switching transients.
The device is rated for -55 °C to +175 °C operating junction temperature, supports 500 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits 0.086 %/°C VBR temperature coefficient - enabling stable clamping across automotive under-hood thermal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.0 V - Maximum continuous reverse voltage before leakage exceeds 50 μA; sets upper limit for safe operation in 12 V automotive systems. |
| VBR (min/max) | 12.2 V / 13.5 V at 5 mA - Confirmed avalanche onset range; ensures reliable triggering before protected circuit overvoltage. |
| VC @ IPPM | ≤18.2 V at 275 A - Clamped voltage during full 5000 W surge; provides 30%+ margin below typical 24 V rail absolute max. |
| PPPM | 5000 W (10/1000 μs) - Peak surge energy absorption capability; meets ISO 7637-2 Pulse 5a requirements for 12 V systems. |
| TJ max. | +175 °C - Enables direct mounting on chassis or heatsink in engine control units without derating at ambient up to 125 °C. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD per JESD47; required for powertrain and body electronics. |
| Package | P600 - Axial-leaded, UL 94 V-0 molded epoxy case; supports manual or wave soldering (275 °C/10 s max); leads matte tin plated. |
Pinout & Package
P600 package: axial-leaded, cylindrical epoxy body with cathode band marking; overall length 9.5 mm, diameter 9.1 mm; leads 1.32 mm diameter, 25.4 mm minimum straight length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage return path; defines reference for clamping action during positive transients on cathode side. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., battery rail); avalanche conduction occurs when voltage exceeds VBR relative to anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and chassis applications with extended temperature cycling, humidity, and lifetime stress testing. |
| 5000 W peak pulse power | Handles worst-case load dump (ISO 7637-2 Pulse 5a) without degradation; eliminates need for crowbar circuits in 12 V systems. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes voltage overshoot during surge events; protects 16 V-rated MOSFETs and 20 V-input DC-DC converters. |
| Fast response time (<1 ns) | Clamps before transient propagates into sensitive ICs; critical for safeguarding CAN transceivers and microcontroller I/O pins. |
| P600 thermal robustness | Dissipates 8.0 W on infinite heatsink at TL = 75 °C; supports sustained surge duty cycles in industrial motor drives. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A-E3/52 (Vishay) | Lower PPPM (600 W), SMC package, same VWM/VBR range, but 40 A IPPM and 18.2 V VC. | Targeted for board-level signal line protection; insufficient for load dump or high-energy industrial surges. | Select 5KP11AHE3_A/C when surge energy exceeds 600 W or P600 thermal mass is required for repeated events. |
| 1.5KE11A (ON Semiconductor) | Same P600 package and 5000 W rating, but not AEC-Q101 qualified; VBR 12.2–13.5 V, VC 18.2 V, TJ max. 175 °C. | Approved for commercial/industrial use only; excluded from automotive production due to missing AEC-Q101 validation. | Choose 5KP11AHE3_A/C for automotive OEM programs requiring documented AEC-Q101 compliance and traceable lot data. |
Compared with SMBJ11A-E3/52 and 1.5KE11A, the 5KP11AHE3_A/C uniquely combines AEC-Q101 qualification, P600 thermal robustness, and 5000 W surge capacity - making it the only option qualified for safety-critical automotive power rail protection where both reliability and energy handling are mandatory.

FAQ
What is the clamping voltage of the 5KP11AHE3_A/C under full-rated surge conditions?
The 5KP11AHE3_A/C clamps to a maximum of 18.2 V when subjected to its rated 275 A peak pulse current (IPPM), corresponding to the 5000 W peak pulse power rating with a 10/1000 μs waveform. This value is measured per JEDEC test conditions and guarantees voltage limiting during standardized surge events, ensuring downstream 24 V-rated components remain within safe operating limits.
Is the 5KP11AHE3_A/C suitable for automotive applications?
Yes, the 5KP11AHE3_A/C is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body control modules, and infotainment power supplies. Its -55 °C to +175 °C operating junction temperature range, validated HTOL and temperature cycling performance, and compliance with ISO 7637-2 Pulse 5a make it appropriate for under-hood and chassis-mounted applications.
What does the "HE3_A/C" suffix indicate in 5KP11AHE3_A/C?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "A/C" specifies the revision code and packaging format - 800 pieces per 13-inch paper tape and reel, with "C" indicating the preferred package code per Vishay's ordering nomenclature in document 88308.
How does the 5KP11AHE3_A/C compare to smaller-package TVS diodes like SMBJ11A?
The 5KP11AHE3_A/C delivers 5000 W peak pulse power in a P600 package, whereas SMBJ11A offers only 600 W in an SMC package. The larger thermal mass and higher surge current rating (275 A vs. 40 A) make 5KP11AHE3_A/C suitable for load dump and industrial motor drive protection, while SMBJ11A is limited to low-energy signal line applications.
Can the 5KP11AHE3_A/C be used in bidirectional configurations?
No, the 5KP11AHE3_A/C is unidirectional only, as confirmed in the Vishay datasheet. It conducts in reverse bias above VBR and blocks forward current up to 3.5 V at 100 A. For bidirectional surge protection, a separate back-to-back configuration or a dedicated bidirectional TVS such as 5KP11CA would be required.
