Product details
Overview
P6KE510-E3/54 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 485 V minimum breakdown voltage (VBR), 434 V standoff voltage (VWM), 698 V maximum clamping voltage (VC) at 0.86 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 P6KE510-E3/54 datasheet, P6KE510-E3/54 pinout, P6KE510-E3/54 application, or P6KE510-E3/54 equivalent, key selection criteria include verified clamping performance under 10/1000 μs surge, unidirectional polarity confirmation, DO-204AC (DO-15) package compatibility, and compliance with AEC-Q101 for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds VBR (485–535 V), it avalanches into low-impedance conduction, diverting surge current away from downstream ICs. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient); derating begins above TA = 25 °C per Figure 2, with maximum junction temperature rated at 175 °C and operating range from –55 °C to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 434 V - maximum continuous reverse working voltage before leakage exceeds 1 μA; defines safe DC rail operating margin |
| VBR (min/max) | 485 V / 535 V at 1 mA test current - guaranteed avalanche onset range; ensures consistent triggering across production lots |
| VC @ IPPM | 698 V at 0.86 A - maximum clamped voltage during 10/1000 μs transient; determines protected circuit's voltage stress ceiling |
| PPPM | 600 W - peak pulse power handling with 0.01 % duty cycle; supports single-event surge suppression without thermal runaway |
| IFSM | 100 A - non-repetitive forward surge current (8.3 ms half-sine); validates robustness against accidental polarity reversal events |
| TJ max. | 175 °C - maximum junction temperature; enables operation in under-hood automotive environments with minimal heatsinking |
| Package | DO-204AC (DO-15) - axial-leaded, epoxy-molded package with UL 94 V-0 rating; compatible with standard through-hole PCB assembly |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body with cathode band marking. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, rated for 275 °C dip soldering (10 s max). Cathode end identified by color band; anode is unmarked.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts only during forward surge or miswiring events |
| Cathode | Reverse-biased clamping terminal | Connected to higher-potential side (e.g., battery rail); initiates avalanche conduction when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|

| RoHS-compliant, commercial grade | Meets EU Directive 2011/65/EU; suitable for industrial and consumer systems requiring lead-free assembly |
Applications
| Automotive Load-Dump Protection | Industrial Power Supply Input Clamping |
|---|---|
|
Use Scenario: Protects 12 V/24 V vehicle ECUs from alternator load-dump transients up to 60 V for 400 ms.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ440A | DO-214AA package; 440 V VWM, 600 W rating; lower VC (644 V) but smaller footprint | Preferred for space-constrained PCBs where axial leads are impractical; not AEC-Q101 qualified | Select when board real estate is limited and automotive qualification is not required |
| 1.5KE510A | Same DO-204AC package; identical VWM/VBR/VC specs; 1.5 kW rating (10/1000 μs) vs. 600 W | Used where higher single-pulse energy absorption is needed (e.g., heavy-duty industrial controls) | Choose for applications demanding >600 W surge capacity without changing layout or mounting method |
Compared with P6KE510-E3/54, SMBJ440A offers surface-mount convenience at lower voltage rating and no automotive qualification, while 1.5KE510A delivers triple the peak power in the same through-hole package - enabling direct layout reuse where enhanced energy handling is critical.

FAQ
What is the clamping voltage of P6KE510-E3/54 under standard 10/1000 μs surge conditions?
The P6KE510-E3/54 has a maximum clamping voltage (VC) of 698 V when subjected to its rated peak pulse current of 0.86 A with a 10/1000 μs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88369, and defines the upper voltage limit imposed on protected circuitry during transient events.
Is P6KE510-E3/54 suitable for automotive applications?
Yes, P6KE510-E3/54 is AEC-Q101 qualified (per note on page 3 and ordering information), making it suitable for automotive applications including body control modules, lighting drivers, and infotainment power rails. Its 175 °C maximum junction temperature and robust surge capability align with under-hood environmental demands.
What does the "E3/54" suffix indicate in P6KE510-E3/54?
The "E3" denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery containing 4000 units. This matches Vishay's ordering convention shown in the "Ordering Information" section of document 88369.
How does P6KE510-E3/54 differ from bi-directional P6KE510CA variants?
P6KE510-E3/54 is unidirectional with cathode-band marking and specified forward voltage (VF = 5.0 V at 50 A); P6KE510CA is bi-directional, lacks polarity marking, and has symmetric clamping in both directions. The CA variant is used for AC line or differential signal protection, whereas P6KE510-E3/54 applies to DC rail clamping.
What is the thermal resistance profile of P6KE510-E3/54?
P6KE510-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W at TA = 25 °C. These values enable effective heat dissipation through PCB copper pours or lead-frame conduction, supporting continuous 5.0 W power dissipation at TL = 75 °C per Figure 5.
