Product details
Overview
P6KE100CAHE3/54 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 100 V standoff voltage (VWM), 114–126 V breakdown range (VBR), 137 V maximum clamping voltage at 4.4 A peak pulse current, 600 W peak pulse power rating (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE100CAHE3/54 datasheet, P6KE100CAHE3/54 pinout, P6KE100CAHE3/54 application, or P6KE100CAHE3/54 equivalent, this device is selected for robust overvoltage protection in automotive sensor interfaces, industrial I/O lines, and telecom power rails where fast response (<1 ns), low clamping ratio, and repeatable surge immunity are critical.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction enables stable breakdown behavior and low incremental surge resistance, while the DO-15 package supports lead-free soldering per J-STD-002 and withstands 275 °C for 10 s per JESD 22-B106.
The device delivers 600 W peak pulse power handling under 10/1000 μs waveform at 0.01% duty cycle, with thermal resistance of 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient). It maintains operation from –55 °C to +175 °C junction temperature and exhibits a temperature coefficient of 0.106 %/°C for VBR.

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) from load-dump and jump-start transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between sensor line and ground, conducting only during overvoltage events. Use Value: Prevents latch-up or permanent damage to microcontroller ADC inputs and transceiver front-ends under ±100 V transients. | Use Scenario: Shielding digital input channels of programmable logic controllers from inductive kickback when controlling solenoids or relays. IC Role / Device Role / Timing Role: Primary overvoltage shunt element on 24 V DC input terminals, absorbing energy before it reaches optocoupler or level-shifter ICs. Use Value: Extends field service life by eliminating false triggering and component degradation caused by repetitive 600 V/1 A surges. |
| Telecom Power Rail Protection | Consumer USB Port Surge Suppression |
Use Scenario: Safeguarding 48 V PoE-powered equipment (e.g., IP cameras, access points) against lightning-induced surges on data/power lines. IC Role / Device Role / Timing Role: Secondary-level TVS on DC input rail, coordinated with primary GDT or MOV for staged clamping. Use Value: Limits rail collapse to ≤137 V during 10/1000 μs surges, preserving operation of DC-DC converters and Ethernet PHYs. | Use Scenario: Adding transient immunity to USB 2.0 VBUS lines in portable chargers and docking stations exposed to ESD and hot-plug events. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp between VBUS and ground, placed upstream of USB switch ICs. Use Value: Maintains signal integrity by limiting VBUS overshoot to <140 V while adding <0.5 pF parasitic capacitance. |
Equivalent & Alternatives

FAQ
What is the clamping voltage of P6KE100CAHE3/54 under maximum rated surge current?
The P6KE100CAHE3/54 has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 4.4 A using the standard 10/1000 μs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuits during transient events, ensuring downstream components remain within safe operating limits.
Is P6KE100CAHE3/54 suitable for automotive applications?
Yes, P6KE100CAHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-glass-passivated junction, DO-15 package with matte tin leads, and operation up to +175 °C-meets stress test requirements for engine control units, body electronics, and ADAS sensor interfaces. The HE3 suffix confirms AEC-Q101 compliance per Vishay's ordering nomenclature.
How does the bidirectional configuration of P6KE100CAHE3/54 affect its circuit placement?
The bidirectional nature of P6KE100CAHE3/54 means it functions identically in both polarities, so no orientation is required during placement-it connects between the protected line and ground with no anode/cathode distinction. This simplifies layout for AC-coupled signals, differential buses (e.g., RS-485), or floating power domains where polarity reversal may occur.
What is the standoff voltage rating for P6KE100CAHE3/54, and how does it relate to system operating voltage?
P6KE100CAHE3/54 has a standoff voltage (VWM) of 85.5 V, meaning it remains non-conductive up to this DC or RMS voltage. For reliable operation, system nominal voltage must stay below VWM with margin-for example, it protects 72 V battery systems (e.g., commercial vehicles) where 85.5 V provides ≥18% headroom above maximum float charge voltage.
Does P6KE100CAHE3/54 require a heatsink for continuous power dissipation?
No, P6KE100CAHE3/54 is rated for 5.0 W power dissipation on an infinite heatsink at TL = 75 °C, but it is intended for transient-only operation-not continuous DC power handling. Its RθJL of 20 °C/W ensures adequate self-cooling during short-duration surges; sustained power dissipation would exceed ratings and cause thermal runaway.
