Product details
Overview
P6KE27HE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 27 V breakdown voltage (VBR min/max = 25.7–28.4 V), 23.1 V stand-off voltage (VWM), 37.5 V clamping voltage at 16.0 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive ECU power inputs and industrial sensor interfaces.
For engineers reviewing the P6KE27HE3/73 datasheet, P6KE27HE3/73 pinout, P6KE27HE3/73 application, or P6KE27HE3/73 equivalent, this AEC-Q101 qualified, RoHS-compliant TVS offers validated surge immunity for 12 V/24 V systems, low incremental surge resistance, and fast response time to protect MOSFETs, microcontrollers, and CAN transceivers against inductive switching transients and load dump events.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (<1 μA leakage at 23.1 V), but triggers into low-impedance conduction when transient voltage exceeds its 25.7 V minimum breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and repeatable clamping performance across temperature (−55 °C to +175 °C).
The P6KE27HE3/73 delivers 600 W peak pulse power handling with 10/1000 μs waveform, supported by thermal resistance RθJL = 20 °C/W and RθJA = 75 °C/W. Its 100 A IFSM rating enables robustness against 8.3 ms half-sine surges, while VF = 3.5 V at 50 A confirms low forward conduction loss during bidirectional fault scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V - defines precise voltage threshold at which clamping begins; ±5% tolerance ensures predictable trigger point in 12 V/24 V rail protection |
| VWM | 23.1 V - maximum continuous reverse operating voltage; allows safe margin below VBR to avoid leakage-induced power loss |
| VC @ IPPM | 37.5 V at 16.0 A - clamped voltage seen by protected IC during worst-case 600 W transient; limits stress on downstream 30 V-rated components |
| IPPM | 16.0 A - peak surge current capability with 10/1000 μs waveform; sufficient for ISO 7637-2 Pulse 1/2a/5a compliance in automotive applications |
| PPPM | 600 W - standardized surge power rating; enables single-device protection without parallel stacking in space-constrained PCB layouts |
| TJ max | +175 °C - extended junction temperature rating supports under-hood automotive use and high-ambient industrial environments |
| AEC-Q101 | Qualified - verified reliability for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or low-side return path; conducts during positive transients on cathode-connected line |
| Cathode | Reverse-biased terminal | Connected to protected line (e.g., 12 V rail); blocks normal operation, avalanches during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR and low leakage over lifetime; eliminates surface contamination risks in humid or contaminated environments |
| 600 W peak pulse power (10/1000 μs) | Enables single-device protection against severe transients like ISO 16750-2 load dump without derating or parallel devices |
| AEC-Q101 qualification | Validates reliability for automotive powertrain and body electronics - includes HTGB, HTRB, and temperature cycling tests |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage overshoot during clamping; protects 30 V-rated MOSFETs and logic ICs without additional series impedance |
| Matte tin plating & JESD 201 Class 2 whisker resistance | Prevents tin whisker growth in high-reliability automotive assemblies; eliminates risk of latent short-circuits in long-life modules |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V battery rail in engine control unit exposed to load dump (ISO 16750-2 Pulse 5a) and alternator ripple.

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; lower 400 W PPPM; VBR = 26.7–29.5 V; VC = 38.9 V @ 10.3 A | Surface-mount alternative for automated assembly; less surge margin than P6KE27HE3/73's 600 W rating | Select SMBJ24A only when board space constraints prohibit axial DO-15 placement and 400 W surge capacity suffices. |
| 1.5KE27A | Same DO-204AC package; higher 1500 W PPPM; VBR = 25.7–28.4 V; VC = 43.0 V @ 34.9 A | Higher-power legacy variant with larger junction; requires more PCB copper area for thermal dissipation | Choose 1.5KE27A where ISO 7637-2 Pulse 5b (1000 W) immunity is mandated and layout allows larger thermal pad. |
Compared with SMBJ24A and 1.5KE27A, the P6KE27HE3/73 uniquely balances AEC-Q101 qualification, 600 W surge capability, and DO-15 through-hole compatibility - making it optimal for automotive replacement modules and industrial field-serviceable designs requiring proven reliability and manual reworkability.

FAQ
What is the breakdown voltage range for P6KE27HE3/73?
The P6KE27HE3/73 has a specified breakdown voltage (VBR) range of 25.7 V to 28.4 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This ±5% tolerance ensures consistent triggering behavior across production lots and temperature ranges, critical for reliable protection of 24 V nominal systems where overvoltage margins must be tightly controlled. The P6KE27HE3/73 maintains this specification under AEC-Q101 stress conditions.
Is P6KE27HE3/73 suitable for automotive applications?
Yes, the P6KE27HE3/73 is AEC-Q101 qualified and specifically rated for automotive use, including engine control units, body control modules, and infotainment power supplies. Its +175 °C maximum junction temperature, glass-passivated junction, and JESD 201 Class 2 whisker resistance meet stringent automotive reliability requirements. The P6KE27HE3/73 has been validated against ISO 7637-2 Pulse 1, 2a, and 5a transients in reference designs from Vishay.
What is the clamping voltage of P6KE27HE3/73 at its rated peak pulse current?
The P6KE27HE3/73 clamps to a maximum of 37.5 V at its rated peak pulse current (IPPM) of 16.0 A, tested with a 10/1000 μs waveform. This clamping voltage directly determines the maximum stress imposed on downstream components - for example, ensuring 30 V-rated MOSFETs remain within safe operating area. The P6KE27HE3/73 achieves this with a clamping ratio (VC/VBR) of approximately 1.39, among the lowest in its class.
How does the HE3 suffix differ from E3 in P6KE27HE3/73?
The HE3 suffix in P6KE27HE3/73 indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes RoHS compliance and commercial-grade qualification only. The P6KE27HE3/73 undergoes additional stress testing including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling to validate automotive reliability. Both share identical electrical specs and DO-204AC packaging, but only HE3 is approved for under-hood deployment.
Can P6KE27HE3/73 be used in bi-directional protection circuits?
No - the P6KE27HE3/73 is a uni-directional TVS diode, identifiable by its cathode band marking. For bi-directional protection, Vishay specifies the CA-suffixed variant (e.g., P6KE27CA). Using P6KE27HE3/73 in AC or floating signal paths would result in forward conduction during negative half-cycles, causing failure. Always match polarity: P6KE27HE3/73 for DC rail-to-ground clamping, P6KE27CA for symmetrical line-to-line or data-line protection.
