Product details

Overview

5KP15A-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 15 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR), 5000 W peak pulse power (10/1000 μs), 24.4 V maximum clamping voltage at 205 A, and AEC-Q101 qualification for automotive-grade reliability.

For engineers reviewing the 5KP15A-E3/54 datasheet, 5KP15A-E3/54 pinout, 5KP15A-E3/54 application, or 5KP15A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC V_DD, peak surge current handling under lightning/inductive-switching transients, thermal derating above 25 °C, and P600 PCB footprint compatibility with high-current trace routing.

Technical Context

This TVS operates as a voltage-clamped crowbar device-triggering into low-impedance conduction when reverse voltage exceeds VBR, limiting downstream voltage to ≤24.4 V during 10/1000 μs surges up to 205 A. Its glass-passivated P600 junction enables robust 5000 W pulse handling with low incremental surge resistance and sub-nanosecond response time.

Designed for DC power rail protection, it replaces discrete crowbar circuits in switching power supplies and supports fail-safe operation by allowing fuses/circuit breakers time to clear faults while sustaining repeated transients. Thermal performance is governed by lead temperature (TL) derating per Fig. 5, with 8.0 W steady-state dissipation on infinite heatsink at TL = 75 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	15.0 V - Maximum continuous reverse operating voltage before leakage exceeds 2.0 μA; sets upper limit for normal circuit bias.
V_BR @ I_T = 5 mA	16.7–18.5 V - Measured breakdown range defining reliable turn-on threshold under standardized test current.
V_C @ I_PPM = 205 A	24.4 V - Clamped voltage during full-rated 5000 W transient; determines maximum stress on downstream components.
P_PPM	5000 W - Peak pulse power rating for 10/1000 μs waveform; defines energy absorption capability per transient event.
I_FSM	500 A - Non-repetitive forward surge current (8.3 ms half-sine); supports high-current fault clearing without bond wire failure.
T_J Range	–55 °C to +175 °C - Extended junction temperature range enabling under-hood automotive and industrial deployment.
AEC-Q101	Qualified - Validated for automotive electronic systems per stress test requirements including HTGB, HTRB, and TCT.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Littelfuse SMAJ15A	Lower peak power (400 W), smaller SMA package, 24.4 V clamping at 16.7 A (not 205 A)	Suitable for low-energy signal-line protection; insufficient for 12 V power rail IEC 61000-4-5 compliance	Select 5KP15A-E3/54 when protecting high-current DC rails requiring ≥5000 W surge handling.
ON Semiconductor 1.5KE15A	Same P600 package and 15 V V_WM, but lower PPPM (1500 W), higher V_C (25.1 V at 59.5 A)	Acceptable for cost-sensitive industrial controls with moderate surge exposure; not AEC-Q101 qualified	Choose 5KP15A-E3/54 for automotive or high-reliability applications demanding AEC-Q101 and full 5 kW rating.

Compared with SMAJ15A and 1.5KE15A, the 5KP15A-E3/54 delivers 3.3× higher pulse power and automotive qualification-critical for protecting 12 V/24 V power domains where single-event robustness and long-term field reliability are non-negotiable.

FAQ

What is the maximum clamping voltage of the 5KP15A-E3/54 under full-rated surge conditions?

The 5KP15A-E3/54 exhibits a maximum clamping voltage (V_C) of 24.4 V when subjected to its rated peak pulse current of 205 A (10/1000 μs waveform). This value is measured per JEDEC standards and guarantees that protected circuitry downstream will not experience voltages exceeding 24.4 V during worst-case transients, provided layout minimizes parasitic inductance.

Is the 5KP15A-E3/54 suitable for automotive applications?

Yes-the 5KP15A-E3/54 carries AEC-Q101 qualification, confirming its suitability for automotive environments including engine control units, body electronics, and ADAS modules. Its –55 °C to +175 °C operating junction temperature range, robust P600 package, and validated reliability under temperature cycling and humidity testing meet stringent automotive requirements.

How does the 5KP15A-E3/54 differ from standard 1.5KE series TVS diodes?

The 5KP15A-E3/54 delivers 5000 W peak pulse power-more than three times the 1500 W rating of the 1.5KE15A-while maintaining identical 15 V stand-off voltage and P600 packaging. It also features lower clamping voltage (24.4 V vs. 25.1 V) at higher surge current (205 A vs. 59.5 A) and includes AEC-Q101 qualification, which the 1.5KE series lacks.

What is the meaning of the "E3/54" suffix in 5KP15A-E3/54?

The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery containing 800 units. This ordering format ensures traceable, automated assembly-ready packaging aligned with Vishay's standard logistics configuration.

Can the 5KP15A-E3/54 be used in bidirectional configurations?

No-the 5KP15A-E3/54 is unidirectional only, with polarity indicated by a cathode band. For bidirectional transient suppression (e.g., AC lines or differential data buses), a separate bidirectional TVS such as the 5KP15CA must be selected; mixing unidirectional devices in back-to-back configuration is not recommended due to mismatched V_BR tolerance and thermal imbalance risks.
