Product details
Overview
P6KE27AHE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of 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 at 16.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive body control modules to safeguard microcontroller I/O against load-dump transients.
For engineers reviewing the P6KE27AHE3/73 datasheet, P6KE27AHE3/73 pinout, P6KE27AHE3/73 application, or P6KE27AHE3/73 equivalent, this device is evaluated for bidirectional surge immunity in AEC-Q101 qualified systems, clamping performance under repetitive 0.01% duty cycle pulses, thermal derating above 25 °C, and compatibility with J-STD-002 solderability standards on matte tin-plated leads.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (23.1 V), it avalanches into low-impedance conduction, limiting transient energy to downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), critical for suppressing ESD and inductive switching spikes before IC damage occurs.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient); power dissipation is limited to 5.0 W on infinite heatsink at TL = 75 °C. The device is rated for TJ = –55 to +175 °C and qualified per AEC-Q101 - confirming robustness in under-hood automotive environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient 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; same AEC-Q101 qualification | Surface-mount footprint; higher board density but requires reflow profile validation | Select SMBJ24A when space-constrained PCB layout favors SMD over axial leaded components |
| 1.5KE27A | Same DO-15 package; 27 V VBR; 37.5 V VC @ 16.0 A; 1500 W PPPM; commercial grade only (not AEC-Q101) | Higher surge capacity but lacks automotive qualification and whisker-tested leads | Choose 1.5KE27A for cost-sensitive industrial applications where AEC-Q101 is not mandated |
Compared with SMBJ24A and 1.5KE27A, P6KE27AHE3/73 uniquely combines AEC-Q101 qualification, HE3 whisker-tested leads, and DO-15 through-hole reliability - making it optimal for automotive production where traceable sourcing and long-term supply continuity are mandatory.

FAQ
What is the clamping voltage of P6KE27AHE3/73 at its rated peak pulse current?
The P6KE27AHE3/73 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 per JEDEC test conditions and reflects the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6KE27AHE3/73 suitable for automotive applications?
Yes, P6KE27AHE3/73 is AEC-Q101 qualified and carries the HE3 suffix indicating compliance with JESD 201 Class 2 whisker testing - confirming suitability for automotive under-hood and cabin applications. Its operating junction temperature range (–55 to +175 °C), thermal resistance (RθJL = 20 °C/W), and load-dump surge capability align with ISO 7637-2 requirements for body electronics and power distribution modules.
How does the HE3 suffix differ from the E3 suffix in P6KE27AHE3/73?
The HE3 suffix in P6KE27AHE3/73 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates RoHS-compliant commercial-grade parts without automotive qualification. HE3 parts undergo extended reliability testing including temperature cycling, high-temperature reverse bias, and accelerated moisture resistance - essential for automotive production use where field failure risk must be minimized.
What is the maximum steady-state power dissipation for P6KE27AHE3/73?
P6KE27AHE3/73 has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. This rating assumes ideal thermal conduction and is derated linearly above 25 °C ambient per the published power derating curve - actual usable power depends on PCB copper area, airflow, and enclosure thermal design.
Can P6KE27AHE3/73 be used in bidirectional configurations?
No, P6KE27AHE3/73 is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional operation requires the CA-suffixed variant (e.g., P6KE27CA). Using P6KE27AHE3/73 in AC-coupled or symmetrical transient scenarios would result in forward conduction during negative half-cycles, potentially causing overheating or failure - always match polarity to circuit topology.
