Product details
Overview
P6KE100CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 137 V maximum clamping voltage at 4.4 A peak pulse current, and 85.5 V stand-off voltage - enabling robust protection of MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the P6KE100CA-E3/54 datasheet, P6KE100CA-E3/54 pinout, P6KE100CA-E3/54 application, or P6KE100CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, and verified 175 °C junction temperature rating under transient stress.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse or forward voltage exceeds its breakdown threshold (95.0–105 V at 1 mA), it rapidly transitions to low-impedance conduction to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable avalanche characteristics and repeatable clamping performance across thermal cycles.
The P6KE100CA-E3/54 exhibits symmetric bidirectional behavior - electrical characteristics apply identically in both polarities - with no polarity marking on the case. Its thermal resistance (RθJL = 20 °C/W) supports reliable power dissipation up to 5.0 W on an infinite heatsink at 75 °C lead temperature, while maintaining operation from –55 °C to +175 °C junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains single high-energy transients without degradation, suitable for lightning-induced surges per IEC 61000-4-5 Level 4 |
| Stand-off Voltage (VWM) | 85.5 V - maximum continuous operating voltage before significant leakage; sets upper limit for protected line voltage |
| Breakdown Voltage (VBR) | 95.0–105 V at 1 mA - defines precise avalanche initiation point; ensures predictable turn-on during overvoltage events |
| Maximum Clamping Voltage (VC) | 137 V at 4.4 A IPPM - limits voltage seen by protected ICs during worst-case surge, critical for 100 V-rated components |
| Peak Pulse Current (IPPM) | 4.4 A - quantifies surge-handling capacity; derived from 600 W / 137 V, validated per Fig. 1 derating curve |
| Junction Temperature Range | –55 °C to +175 °C - enables deployment in under-hood automotive, motor drives, and industrial control environments |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard |
Pinout & Package
Package: DO-15 (DO-204AC) - axial-leaded, molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability requirements. Dimensions: 3.3–3.5 mm diameter × 25.4 mm minimum length; lead length 6.15–6.55 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Bidirectional terminal pair | No polarity marking - symmetrical structure allows installation in either orientation; functions identically for positive or negative transients |
| Leads (both) | Surge current path | Carry full IPPM during clamping; thermal resistance RθJL = 20 °C/W ensures safe heat transfer to PCB copper or heatsink |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Same 100 V nominal breakdown but in SMB (DO-214AA) package; 600 W rating, lower RθJA (50 °C/W vs. 75 °C/W) | Surface-mount layout; better thermal performance on dense PCBs but requires rework for through-hole legacy designs | Select when board space is constrained and automated SMT assembly is used; verify pad thermal relief for 5.0 W dissipation |
| 1.5KE100CA | Higher 1500 W peak power rating; same DO-15 package; 100 V VBR, 156 V VC at 9.6 A | Higher-energy surge environments (e.g., industrial motor drives); larger physical size increases mounting clearance needs | Choose for applications exceeding 600 W surge budgets; confirm mechanical fit - 1.5KE series has longer body (4.5 mm vs. 3.4 mm diameter) |
Compared with SMBJ100CA and 1.5KE100CA, the P6KE100CA-E3/54 offers optimal balance of proven DO-15 reliability, AEC-Q101 qualification, and cost-effective 600 W protection - making it preferred for automotive and industrial through-hole designs where layout change is not feasible.

FAQ
What is the clamping voltage of P6KE100CA-E3/54 at its rated peak pulse current?
The P6KE100CA-E3/54 has a maximum clamping voltage (VC) of 137 V at 4.4 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88369 and defines the upper voltage limit imposed on protected circuitry during worst-case surge conditions. The P6KE100CA-E3/54 maintains this clamping performance across its full operating temperature range.
Is P6KE100CA-E3/54 suitable for automotive applications?
Yes, the P6KE100CA-E3/54 is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces. Its –55 °C to +175 °C junction temperature range, glass-passivated junction, and DO-15 mechanical robustness meet automotive environmental stress requirements. The P6KE100CA-E3/54 is explicitly listed in Vishay's AEC-Q101 qualified devices table.
How does the bidirectional nature of P6KE100CA-E3/54 affect its circuit placement?
The P6KE100CA-E3/54 has no polarity marking and functions identically in both directions, allowing installation in either orientation across protected lines. This eliminates orientation errors during manual assembly and simplifies layout for AC-coupled or differential signal paths. Unlike unidirectional TVS diodes, the P6KE100CA-E3/54 provides symmetrical clamping for positive and negative transients without requiring external biasing or dual-device configurations.
What is the thermal resistance of P6KE100CA-E3/54, and how does it impact power handling?
The P6KE100CA-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 75 °C lead temperature, it can dissipate 5.0 W continuously - sufficient for repetitive surge duty cycles in industrial controls. Effective PCB copper pour under leads reduces RθJA, directly extending safe operating time during multi-pulse events. The P6KE100CA-E3/54 thermal performance is validated per Figure 5 derating curve.
Can P6KE100CA-E3/54 replace P6KE100A in existing designs?
No - P6KE100CA-E3/54 is bidirectional while P6KE100A is unidirectional; they differ in polarity marking, leakage behavior, and circuit function. The P6KE100CA-E3/54 conducts in both directions above 105 V, whereas P6KE100A blocks reverse voltage and only clamps forward surges. Substitution requires verifying that bidirectional clamping aligns with system-level protection strategy and does not introduce unintended conduction paths.
