For engineers reviewing the P6KE100A-E3/73 datasheet, P6KE100A-E3/73 pinout, P6KE100A-E3/73 application, or P6KE100A-E3/73 equivalent, this page delivers verified electrical parameters, DO-15 terminal mapping, real-world clamping behavior, and validated alternatives for ESD/surge protection design-in.
Technical Context
The P6KE100A-E3/73 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to transients. Its unidirectional polarity uses a cathode band marking and exhibits 0.057 %/°C temperature coefficient of VBR, ensuring stable clamping across -55 °C to +175 °C operating range.
It delivers 137 V clamping at 4.4 A (10/1000 µs), with 5.0 W steady-state power dissipation on infinite heatsink and 20 °C/W junction-to-lead thermal resistance - supporting robust thermal management in compact PCB layouts without active cooling.
Key Specifications

Applications
| Automotive Sensor Protection | Industrial PLC Input Stage |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., oxygen, pressure) from load dump and inductive switching spikes in 12 V vehicle networks. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor signal line and chassis ground, clamping transients before they reach the transceiver's ESD diodes. Use Value: Limits voltage to ≤137 V during 100 V/100 ms load dump (ISO 16750-2), preventing latch-up or gate oxide rupture in 5 V/3.3 V interface ICs. | Use Scenario: Safeguarding 24 V digital input modules in programmable logic controllers against field-wiring induced surges and relay contact bounce. IC Role / Device Role / Timing Role: Primary overvoltage clamp on each isolated input channel, positioned upstream of optocoupler or Schmitt trigger input stage. Use Value: Absorbs 600 W pulses from 400 V/2 Ω source impedance (IEC 61000-4-5), maintaining input logic state integrity during factory floor EMI events. |
| DC Power Rail Protection | Consumer Power Adapter Output |
Use Scenario: Secondary-side overvoltage suppression on 48 V PoE++ or telecom rectifier outputs exposed to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Standoff-rated TVS connected between +48 V output and ground, acting as last-line defense after primary MOV and fuse. Use Value: Clamps 10/1000 µs transients to 137 V within 1 ns, limiting energy delivered to downstream DC-DC converters and avoiding secondary failure cascades. | Use Scenario: Output-stage transient suppression in USB-C PD adapters (20 V output) where cost-sensitive, space-constrained designs require minimal component count. IC Role / Device Role / Timing Role: Unidirectional TVS placed directly at USB-C connector pins, shunting ESD (IEC 61000-4-2 ±15 kV air) and capacitive coupling noise. Use Value: Provides 137 V clamping at 4.4 A while occupying only 3.3 mm × 6.15 mm footprint - enabling compliance with UL 62368-1 without redesigning PCB layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Same VWM (85.5 V), lower PPPM (600 W → 600 W), but SMC package (smaller footprint, higher thermal resistance). | Preferred for surface-mount boards with tight spacing; less suitable for through-hole legacy designs or high-temperature ambient (>105 °C). | Select SMBJ100A when board space is constrained and thermal derating is managed via copper pour. |
| 1.5KE100A | Identical VWM/VBR/VC specs, same DO-15 package, but 1.5 kW PPPM rating - requires larger PCB trace width for surge current handling. | Better suited for high-energy industrial surge environments (e.g., AC mains input filtering) where 600 W is marginal. | Choose 1.5KE100A if system-level testing reveals repeated clamping near P6KE100A-E3/73's 600 W limit. |
Compared with SMBJ100A and 1.5KE100A, P6KE100A-E3/73 offers optimal balance of proven reliability in axial-leaded designs, cost efficiency for medium-volume production, and compatibility with existing DO-15 tooling - making it ideal for legacy industrial control upgrades and automotive aftermarket modules.

FAQ
What is the maximum clamping voltage of the P6KE100A-E3/73 under standard test conditions?
The P6KE100A-E3/73 has a maximum clamping voltage (VC) of 137 V at 4.4 A peak pulse current with a 10/1000 µs waveform, per Vishay Document Number 88369. This value defines the upper voltage limit imposed on protected circuitry during surge events and is measured at TA = 25 °C. The P6KE100A-E3/73 maintains this clamping performance across its full operating temperature range due to its low 0.057 %/°C VBR temperature coefficient.
Is the P6KE100A-E3/73 suitable for automotive applications requiring AEC-Q101 qualification?
No, the P6KE100A-E3/73 is a commercial-grade part with RoHS compliance but not AEC-Q101 qualified. For automotive use, Vishay specifies the P6KE100AHE3/73 variant (HE3 suffix), which undergoes stress testing per AEC-Q101. The P6KE100A-E3/73 remains appropriate for non-safety-critical aftermarket modules or industrial equipment where qualification is not mandated.
What is the standoff voltage rating of the P6KE100A-E3/73, and how does it relate to system voltage selection?
The P6KE100A-E3/73 has a maximum stand-off voltage (VWM) of 85.5 V, meaning it remains non-conductive up to this DC or RMS voltage with leakage <1 µA. To ensure reliable operation, system nominal voltage must be ≤80 % of VWM; thus, P6KE100A-E3/73 is recommended for 72 V DC systems (e.g., Class 4 PoE++, telecom battery backups). This margin prevents false triggering while preserving headroom for ripple and transients.
How does the DO-15 package of the P6KE100A-E3/73 impact thermal performance in high-power surge scenarios?
The DO-15 package of the P6KE100A-E3/73 provides a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling effective heat transfer to PCB copper or heatsinks during short-duration surges. However, its junction-to-ambient resistance (RθJA) is 75 °C/W, so sustained power dissipation >5.0 W requires external thermal management. In practice, the P6KE100A-E3/73 handles 600 W pulses safely because energy is brief (≤1 ms), not continuous - confirming its suitability for transient-only protection.
Can the P6KE100A-E3/73 be used in bidirectional configurations?
No, the P6KE100A-E3/73 is strictly unidirectional, indicated by its "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6KE100CA). Using P6KE100A-E3/73 in AC or symmetrical signal paths would result in forward conduction during negative half-cycles, causing failure. For bidirectional protection, select P6KE100CA or equivalent, which clamps equally in both polarities with matched VBR and VC.
