Product details
Overview
5KP14A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on power rails and signal lines. It features 14.0 V stand-off voltage (VWM), 15.6–17.2 V breakdown voltage (VBR) at 5 mA, 23.2 V maximum clamping voltage at 216 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 5KP14A-E3/54 datasheet, 5KP14A-E3/54 pinout, 5KP14A-E3/54 application, or 5KP14A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VCC, peak pulse current capability under lightning-induced transients, thermal derating above 25 °C, and AEC-Q101 qualification status for automotive deployment.
Technical Context
The 5KP14A-E3/54 operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 15.6–17.2 V breakdown range. Its glass-passivated P600 junction delivers low incremental surge resistance and sub-nanosecond response time to clamp fast-rising transients from inductive switching or ESD events.
It sustains 5000 W peak pulse power (10/1000 μs) with 0.01 % duty cycle, dissipates 8.0 W continuously on infinite heatsink at TL = 75 °C, and handles 500 A non-repetitive forward surge current (8.3 ms half-sine). Junction temperature range is –55 °C to +175 °C, supporting under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 14.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum margin below protected circuit's max rated voltage. |
| VBR (min/max) | 15.6 V / 17.2 V at 5 mA - Confirmed avalanche onset range; ensures reliable triggering without premature conduction during normal operation. |
| VC @ IPPM | 23.2 V at 216 A - Clamped voltage during full-rated 10/1000 μs surge; must stay below protected device's absolute maximum rating. |
| PPPM | 5000 W - Peak transient energy absorption capacity; enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω). |
| IFSM | 500 A - Non-repetitive forward surge rating; supports crowbar-style fault clearing in DC power systems without catastrophic failure. |
| TJ max. | +175 °C - Maximum junction temperature; allows operation in high-ambient environments like engine control units or industrial motor drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ14A | Lower peak power (400 W), SMC package (smaller footprint), 23.2 V VC at 22.5 A IPPM - not suitable for 5 kV-level surges. | Targeted at board-level ESD/surge protection where space is constrained but energy levels are lower (IEC 61000-4-2/4-4). | Select SMAJ14A only if system-level surge testing is limited to Level 2 (1 kV) and PCB real estate prohibits P600 mounting. |
| ON Semiconductor 1.5KE14A | Same P600 package, 5000 W rating, but higher clamping voltage (25.5 V at 193 A) and no AEC-Q101 qualification. | Acceptable for industrial/commercial power supplies lacking automotive qualification requirements. | Choose 1.5KE14A when AEC-Q101 is not mandated and design tolerates 2.3 V higher clamping voltage than 5KP14A-E3/54. |
Compared with SMAJ14A and 1.5KE14A, the 5KP14A-E3/54 uniquely combines automotive qualification, lowest clamping voltage (23.2 V), and full 5000 W surge capacity in P600 - making it the preferred choice for safety-critical 12 V/24 V power rail protection where reliability and margin are non-negotiable.

FAQ
What is the maximum clamping voltage of the 5KP14A-E3/54 under full-rated surge conditions?
The 5KP14A-E3/54 exhibits a maximum clamping voltage (VC) of 23.2 V when subjected to its rated peak pulse current of 216 A using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and represents the upper limit of voltage seen by protected circuitry during worst-case transient events.
Is the 5KP14A-E3/54 qualified for automotive applications?
Yes, the 5KP14A-E3/54 is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 16-Mar-2023. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and surge endurance - validating its suitability for under-hood and chassis-mounted automotive electronics.
What does the "E3/54" suffix indicate in the 5KP14A-E3/54 part number?
The "E3" denotes RoHS-compliant, commercial-grade termination meeting JESD 201 Class 1A whisker resistance, while "/54" specifies the preferred packaging code: 800 units per 13-inch paper tape and reel. This format aligns with Vishay's standardized ordering nomenclature for P600 devices.
Can the 5KP14A-E3/54 be used in bidirectional configurations?
No, the 5KP14A-E3/54 is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts in reverse bias during overvoltage events and blocks forward current up to 3.5 V at 100 A. For bidirectional protection, a separate back-to-back diode configuration or a dedicated bidirectional TVS (e.g., 5KP14CA) is required.
How does thermal derating affect the 5KP14A-E3/54's surge capability above 25 °C ambient?
The 5KP14A-E3/54's peak pulse power rating decreases linearly above 25 °C ambient, per Figure 2 in the datasheet. At 100 °C, its PPPM is derated to approximately 65 % of 5000 W (~3250 W), and at 175 °C junction temperature, it reaches zero usable surge capacity - necessitating proper PCB copper pour or heatsinking in high-temperature deployments.
