Product details
Overview
P6KE75HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 71.3 V minimum breakdown voltage (VBR), 64.1 V maximum standoff voltage (VWM), 103 V clamping voltage (VC) at 5.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the P6KE75HE3/73 datasheet, P6KE75HE3/73 pinout, P6KE75HE3/73 application, or P6KE75HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package, 175 °C max junction temperature, and verified clamping performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR, 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 protecting MOSFET gates and microcontroller I/O pins against ESD and inductive switching spikes.
The device is rated for 100 A non-repetitive forward surge current (IFSM) and exhibits 0.105 %/°C temperature coefficient of VBR. Thermal resistance is 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient), enabling reliable operation up to 175 °C junction temperature without derating in lead-soldered PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V maximum - defines highest continuous DC or RMS voltage the device blocks without leakage exceeding 1 μA |
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA - ensures predictable avalanche initiation across production lot and temperature range |
| VC @ IPPM | 103 V at 5.8 A - maximum clamped voltage seen by protected IC during 10/1000 μs surge, limiting stress on downstream components |
| PPPM | 600 W - peak transient power dissipation capability with standard 10/1000 μs waveform, supporting IEC 61000-4-5 Level 4 compliance |
| IFSM | 100 A - single half-sine surge rating (8.3 ms), validating robustness against motor commutation or relay coil kickback |
| TJ max | 175 °C - enables use in under-hood automotive environments and high-temperature industrial enclosures without thermal shutdown |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports efficient heat transfer through PCB copper pour or heatsinked leads |
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. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to system ground or low-side reference | Provides return path for surge current during clamping; must be routed with low-inductance trace to minimize V = L·di/dt overshoot |
| Cathode | Current exit terminal in forward bias; connected to protected line (e.g., +12 V rail or signal input) | Acts as voltage-sensing node - clamping initiates when cathode-to-anode voltage exceeds VBR; polarity marking essential for correct placement |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics, with extended temperature cycling and HTRB testing |
| Glass passivated junction | Ensures stable VBR tolerance (±5 %) and low leakage (<1 μA at VWM) over 15+ year field life in humid environments |
| 600 W peak pulse power | Supports protection against 1 kV/500 A IEC 61000-4-5 combination wave surges without degradation after 1000 pulses |
| Fast response time (<1 ns) | Clamps transients before sensitive CMOS inputs reach destructive voltage thresholds - critical for CAN/LIN bus and MCU reset lines |
| Low incremental surge resistance | Minimizes VC overshoot during high-di/dt events, reducing risk of latch-up in adjacent logic devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | Same VWM (64.1 V) and VC (103 V), but SMC package (DO-214AB); 1000 W PPPM rating | Higher power handling suits higher-energy surges; larger footprint requires PCB redesign | Select SMBJ75A when surge energy exceeds 600 W or board space allows SMC package |
| 1.5KE75A | Same DO-204AC package and electrical specs, but commercial-grade (non-AEC-Q101); 1.5 kW PPPM | Lacks automotive qualification; suitable for consumer/industrial only where AEC-Q101 not mandated | Choose 1.5KE75A for cost-sensitive non-automotive designs requiring identical form factor and clamping behavior |
Compared with SMBJ75A and 1.5KE75A, P6KE75HE3/73 uniquely delivers AEC-Q101 qualification in the compact DO-15 package - enabling automotive integration without layout change or derating, while maintaining identical VWM, VBR, and VC performance.

FAQ
What is the clamping voltage of P6KE75HE3/73 at its rated peak pulse current?
The P6KE75HE3/73 has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The P6KE75HE3/73 maintains this clamping performance across its full operating temperature range (-55 °C to +175 °C).
Is P6KE75HE3/73 suitable for automotive applications?
Yes, P6KE75HE3/73 is AEC-Q101 qualified and specifically rated for automotive use, including engine control modules, body electronics, and infotainment power supplies. Its DO-204AC package, 175 °C maximum junction temperature, and validated performance under temperature cycling and HTRB testing confirm suitability for under-hood and cabin environments. The HE3 suffix denotes AEC-Q101 qualification per Vishay's ordering nomenclature.
How does the P6KE75HE3/73 differ from the standard P6KE75A?
The P6KE75HE3/73 differs from P6KE75A in two key aspects: it carries the HE3 suffix indicating AEC-Q101 qualification and RoHS compliance, whereas P6KE75A is commercial-grade only. Both share identical electrical specifications (VWM = 64.1 V, VBR = 71.3–78.8 V, VC = 103 V), DO-204AC package, and thermal ratings. The HE3 variant undergoes additional automotive reliability testing and whisker resistance validation per JESD 201 Class 2.
What is the standoff voltage rating for P6KE75HE3/73?
The P6KE75HE3/73 has a maximum working peak reverse voltage (VWM) of 64.1 V, meaning it reliably blocks voltages up to this level with reverse leakage current ≤1 μA at 25 °C. This rating ensures compatibility with nominal 48 V and 60 V DC systems, including telecom feeders and industrial controls, while providing sufficient margin below the 71.3 V minimum breakdown voltage to prevent premature conduction.
Can P6KE75HE3/73 be used in bi-directional protection circuits?
No, P6KE75HE3/73 is a unidirectional TVS diode - its cathode band indicates polarity, and it conducts only when anode is negative relative to cathode. For bi-directional protection, Vishay specifies the CA-suffixed variant (e.g., P6KE75CA). Using P6KE75HE3/73 in AC or symmetric transient scenarios would result in forward conduction during negative half-cycles, potentially damaging the device or failing to protect.
