Product details
Overview
5KP14AHE3_A/C from Vishay General Semiconductor is a unidirectional 5000 W transient voltage suppressor (TVS) diode in P600 package, with 14.0 V stand-off voltage (VWM), 15.6–17.2 V breakdown voltage (VBR), and 23.2 V clamping voltage (VC) at 216 A peak pulse current. It is AEC-Q101 qualified and designed for automotive and industrial overvoltage protection of power rails and signal lines.
For engineers reviewing the 5KP14AHE3_A/C datasheet, 5KP14AHE3_A/C pinout, 5KP14AHE3_A/C application, or 5KP14AHE3_A/C equivalent, key selection criteria include clamping performance under 10/1000 µs surge, unidirectional polarity, P600 thermal derating behavior, and AEC-Q101 qualification status for harsh-environment deployment.
Technical Context
The 5KP14AHE3_A/C uses a glass-passivated P600 junction to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of lightning-induced transients and inductive switching spikes. Its 5000 W peak pulse power rating is defined per 10/1000 µs waveform at 0.01% duty cycle.
Thermal design requires attention to lead temperature (TL ≤ 75 °C) and junction temperature limits (TJ max = 175 °C); power dissipation is derated linearly above TA = 25 °C per Figure 2, and mounting surface area directly impacts sustained surge handling capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 14.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 15.6 V / 17.2 V - breakdown occurs within this range at 5.0 mA test current |
| VC @ IPPM | 23.2 V - clamps transients to ≤23.2 V when subjected to 216 A 10/1000 µs pulse |
| PPPM | 5000 W - peak pulse power handling under standardized surge waveform |
| IFSM | 500 A - withstands 8.3 ms half-sine surge without failure |
| TJ max | +175 °C - maximum junction temperature for reliable operation and AEC-Q101 compliance |
| Polarity | Unidirectional - cathode marked by color band; blocks reverse current until breakdown |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability requirements. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); color band identifies this end for correct PCB orientation |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14A | Lower PPPM (600 W), SMC package, same VWM (14 V), higher VC (23.2 V) | Not rated for AEC-Q101; suitable only for commercial-grade consumer/industrial use | Select when space-constrained layouts require SMC footprint and automotive qualification is unnecessary |
| 1.5KE14A | Same VWM (14 V), lower PPPM (1500 W), DO-201 package, non-AEC-Q101 | Limited thermal mass; unsuitable for repetitive surges or high ambient temperatures | Choose for cost-sensitive legacy designs where 5000 W surge margin is not required |
Compared with SMBJ14A and 1.5KE14A, the 5KP14AHE3_A/C delivers 3.3× and 3.3× higher peak pulse power respectively, supports automotive qualification, and provides superior thermal robustness via P600 packaging-making it the only option among the three validated for under-hood automotive deployment.

FAQ
What is the clamping voltage of the 5KP14AHE3_A/C and how is it measured?
The 5KP14AHE3_A/C has a maximum clamping voltage (VC) of 23.2 V, measured at its rated peak pulse current (IPPM) of 216 A using a 10/1000 µs waveform per JEDEC standards. This value represents the upper limit of voltage seen by downstream circuitry during a standardized surge event and is guaranteed across the full operating temperature range.
Is the 5KP14AHE3_A/C suitable for automotive applications?
Yes, the 5KP14AHE3_A/C is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, P600 package, and 175 °C maximum junction temperature-meets the environmental and reliability requirements for under-hood and chassis-mounted electronic control units.
What does the "HE3" suffix indicate in 5KP14AHE3_A/C?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. The "_A/C" indicates the preferred packaging code (C = 13" paper tape and reel, 800 units per reel), per Vishay's ordering nomenclature in Document 88308.
How does the 5KP14AHE3_A/C differ from standard Zener diodes?
Unlike general-purpose Zener diodes, the 5KP14AHE3_A/C is optimized for transient suppression-not regulation-with 5000 W peak pulse power, sub-nanosecond response, and robust surge current handling (216 A). Its VBR tolerance and clamping characteristics are specified for surge conditions, not DC bias stability.
Can the 5KP14AHE3_A/C be used in bidirectional configurations?
No, the 5KP14AHE3_A/C is unidirectional only, as confirmed in the Vishay datasheet. For bidirectional protection, a separate part number (e.g., 5KP14CA) must be selected; mixing unidirectional devices in anti-parallel does not replicate true bidirectional TVS performance or ratings.
