Product details
Overview
P6KE75-E3/73 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 standoff voltage (VWM), 103 V maximum 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 body control modules to safeguard microcontrollers against load-dump transients.
For engineers reviewing the P6KE75-E3/73 datasheet, P6KE75-E3/73 pinout, P6KE75-E3/73 application, or P6KE75-E3/73 equivalent, key selection criteria include clamping performance under 5.8 A surge, thermal resistance (RθJL = 20 °C/W), RoHS-compliant DO-204AC (DO-15) packaging, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds VBR (71.3–78.8 V), it avalanches into low-impedance conduction to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
Designed for single-pulse and low-duty-cycle repetitive surges (0.01 %), it sustains 600 W peak pulse power per 10/1000 µs waveform and handles up to 100 A non-repetitive forward surge current (IFSM). Thermal derating begins above TA = 25 °C, with full power dissipation (5.0 W) only achievable at lead temperature TL ≤ 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 64.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VBR (Breakdown Voltage) | 71.3–78.8 V at 1.0 mA test current - defines precise avalanche initiation threshold |
| VC (Clamping Voltage) | 103 V at 5.8 A IPPM - limits protected circuit voltage during worst-case 10/1000 µs surge |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capacity for standardized transient immunity testing |
| RθJL (Junction-to-Lead) | 20 °C/W - enables thermal design with direct PCB copper pour heat sinking |
| TJ max. | 175 °C - supports operation in under-hood automotive environments |

Applications
| Automotive Body Control Module | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller GPIOs from battery reverse connection and alternator load dump. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between VBAT and ground, triggered within <1 ns upon overvoltage. Use Value: Limits voltage to ≤103 V during 5.8 A surge, preventing latch-up or gate oxide damage in 3.3 V/5 V logic ICs. |
Use Scenario: Safeguarding 24 V DC digital input channels against field-wiring induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: Primary protection stage upstream of optocoupler input, absorbing >95 % of transient energy before secondary filtering. Use Value: Enables compliance with IEC 61000-4-5 Level 3 (2 kV surge) without additional series impedance or timing delays. |
| Consumer Power Adapter Output | Telecom DC Power Feed |
Use Scenario: Clamping output overvoltage in 12 V wall adapters caused by feedback loop failure or Zener regulator drift. IC Role / Device Role / Timing Role: Fail-safe crowbar element across regulated output, conducting only during fault conditions.

Use Scenario: Protecting PoE-powered device front-end rectifiers from lightning-induced surges on 48 V DC feed lines. IC Role / Device Role / Timing Role: First-line transient suppressor on DC input, coordinated with upstream gas discharge tube (GDT) for staged protection. Use Value: Provides low-clamp response (<103 V) for fast-rising events where GDT alone exhibits high follow-on current. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | Same VWM (64.1 V) and VC (103 V), but SMC package (higher thermal mass, RθJA = 35 °C/W vs. 75 °C/W) | Better suited for high-temperature ambient (>85 °C) or higher average power dissipation scenarios | Select SMBJ75A when board space allows larger SMC footprint and thermal management requires lower RθJA |
| 1.5KE75A | Identical electrical specs but TO-204AE (DO-41) package; 1.5 kW rating (derated to 600 W at 10/1000 µs per standard) | Higher surge margin for infrequent, extreme transients; less suitable for compact layouts | Choose 1.5KE75A only if legacy DO-41 footprint compatibility is required and mechanical clearance permits larger body |
Compared with SMBJ75A and 1.5KE75A, P6KE75-E3/73 offers optimal balance of DO-15 footprint compatibility, AEC-Q101 qualification, and verified 600 W clamping performance - making it preferred for new automotive and industrial designs where space, qualification, and cost are jointly constrained.

FAQ
What is the clamping voltage of the P6KE75-E3/73 under a 10/1000 µs surge?
The P6KE75-E3/73 clamps to a maximum of 103 V at 5.8 A peak pulse current (IPPM) when subjected to a 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88369 and defines the upper voltage limit imposed on protected circuitry during standardized transient events. The P6KE75-E3/73 maintains this clamping performance across its rated junction temperature range (–55 °C to +175 °C), with minor derating above TA = 25 °C.
Is the P6KE75-E3/73 suitable for automotive applications?
Yes, the P6KE75-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use per Vishay's documentation. Its 175 °C maximum junction temperature, glass-passivated junction, and validation against load-dump and ISO 7637-2 transients make it appropriate for body control modules, lighting drivers, and infotainment power rails. The E3 suffix confirms RoHS compliance and JESD201 Class 1A whisker resistance - both required for modern automotive production.
How does the P6KE75-E3/73 differ from bi-directional TVS diodes like P6KE75CA?
The P6KE75-E3/73 is unidirectional and features a cathode band for polarity identification, enabling DC rail protection where reverse conduction must be blocked. In contrast, P6KE75CA is bi-directional with no polarity marking and symmetric clamping in both directions - used for AC lines or differential signal protection. Electrical parameters differ: P6KE75CA has VWM = 64.1 V and VC = 115 V (vs. 103 V for P6KE75-E3/73), reflecting its dual-path conduction path.
What is the thermal resistance of the P6KE75-E3/73, and how does it affect layout?
The P6KE75-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, meaning each watt dissipated raises the junction temperature 20 °C above the lead temperature. For reliable operation, PCB layout must provide adequate copper area on both leads - especially the cathode - to maintain lead temperature ≤75 °C. Without sufficient copper, power derating is required per Figure 5 in Vishay document 88369. The P6KE75-E3/73 does not specify RθJA due to strong dependence on board layout.
Can the P6KE75-E3/73 replace older P6KE75A variants in existing designs?
Yes, the P6KE75-E3/73 is a direct replacement for P6KE75A with identical electrical specifications, DO-204AC (DO-15) package, and pinout. The "E3/73" suffix indicates RoHS-compliant matte tin plating and packaging in 73 mm tape-and-reel format (4000 pcs/reel), whereas legacy P6KE75A may use non-RoHS leads or different reel configurations. No PCB or schematic changes are needed - the P6KE75-E3/73 maintains full functional and mechanical compatibility with P6KE75A.
