Product details
Overview
P6KE27A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 27 V nominal breakdown voltage (VBR = 25.7–28.4 V at 1 mA), 23.1 V stand-off voltage (VWM), 37.5 V maximum clamping voltage (VC) at 16.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive body electronics, industrial I/O modules, and AC/DC adapter input stages.
For engineers reviewing the P6KE27A-E3/54 datasheet, P6KE27A-E3/54 pinout, P6KE27A-E3/54 application, or P6KE27A-E3/54 equivalent, key selection criteria include verified clamping performance under 16 A surge, DO-15 package thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, and compliance with AEC-Q101 for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (23.1 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), critical for suppressing ESD and inductive switching spikes.
The device is rated for 100 A non-repetitive forward surge current (IFSM) and exhibits a temperature coefficient of 0.096 %/°C on VBR, enabling predictable derating across -55 °C to +175 °C operating junction range. Thermal performance is defined by RθJA = 75 °C/W and RθJL = 20 °C/W, supporting lead-mounted PCB designs without heatsinking for moderate-duty cycles.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | DO-214AA package; 24 V VWM, 38.9 V VC @ 15.4 A; 600 W rating; surface-mount | Requires PCB re-layout for SMD placement; better thermal dissipation in high-density layouts | Select SMBJ24A when board space is constrained and automated assembly is preferred over through-hole. |
| 1.5KE27A | Same DO-15 package; identical VBR (25.7–28.4 V); higher VC = 43.0 V @ 13.9 A; same 600 W rating | Higher clamping voltage reduces protection margin for 3.3 V/5 V logic; suitable only where downstream devices tolerate >43 V stress | Choose 1.5KE27A only if legacy design reuse mandates identical footprint and VBR, accepting elevated clamping risk. |
Compared with P6KE27A-E3/54, SMBJ24A offers superior mounting flexibility but requires layout change, while 1.5KE27A maintains mechanical compatibility yet delivers weaker clamping performance - making P6KE27A-E3/54 the optimal balance of low VC, proven DO-15 reliability, and AEC-Q101 qualification.

FAQ
What is the clamping voltage of P6KE27A-E3/54 at its rated peak pulse current?
The P6KE27A-E3/54 has a maximum clamping voltage (VC) of 37.5 V when subjected to its rated peak pulse current of 16.0 A using the standard 10/1000 μs waveform. This value is measured under controlled test conditions per JEDEC standards and reflects the upper limit of voltage seen by protected circuitry during worst-case surge events. The P6KE27A-E3/54 maintains this clamping performance consistently across its specified operating temperature range.
Is P6KE27A-E3/54 suitable for automotive applications?
Yes, the P6KE27A-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including body electronics, lighting control, and infotainment power rails. Its DO-15 package, 175 °C maximum junction temperature, and validated surge performance under load dump and ISO 7637-2 conditions make it appropriate for under-hood and cabin environments. The E3 suffix specifically denotes RoHS-compliant, AEC-Q101 qualified construction for P6KE27A-E3/54.
How does the VBR tolerance of P6KE27A-E3/54 affect circuit protection design?
The P6KE27A-E3/54 specifies a VBR range of 25.7 V to 28.4 V at 1.0 mA test current, representing ±5% tolerance around the nominal 27 V rating. This tight tolerance ensures predictable turn-on behavior across production lots, allowing designers to set safe margins between VWM (23.1 V) and system operating voltage. For example, in a 24 V nominal system, the P6KE27A-E3/54 provides 0.9 V headroom before conduction begins, minimizing leakage while guaranteeing activation before damaging overvoltage occurs.
What is the thermal resistance of P6KE27A-E3/54, and how does it impact power handling?
The P6KE27A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W. These values mean that under steady-state DC conditions, 5.0 W power dissipation (its rated PD) raises the junction temperature by 100 °C above lead temperature. In practice, the P6KE27A-E3/54 relies on short-duration surge events rather than continuous power, so RθJL governs transient thermal response - enabling effective heat transfer to PCB copper during repetitive pulses when leads are properly soldered.
Can P6KE27A-E3/54 be used in bidirectional configurations?
No, P6KE27A-E3/54 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6KE27CA) and lack polarity marking. Using P6KE27A-E3/54 in bidirectional applications would result in forward conduction during negative transients, potentially causing failure or inadequate protection. For AC or dual-polarity signal lines, the P6KE27A-E3/54 must be paired with a second device or replaced with a certified bidirectional part like P6KE27CA.
