Product details
Overview
P6KE110CA-E3/73 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 110 V breakdown voltage (VBR min/max = 105–116 V), 94.0 V standoff voltage (VWM), 152 V maximum clamping voltage at 3.9 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE110CA-E3/73 datasheet, P6KE110CA-E3/73 pinout, P6KE110CA-E3/73 application, or P6KE110CA-E3/73 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and low leakage (<1.0 μA at VWM) under operating conditions.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical avalanche behavior in both polarities due to its bidirectional construction. Its glass-passivated junction enables fast response time (<1.0 ns), low incremental surge resistance, and stable clamping across temperature (temperature coefficient of VBR = 0.107 %/°C).
It is rated for repetitive 10/1000 μs surges at 0.01 % duty cycle and handles non-repetitive 8.3 ms half-sine forward surges up to 100 A (unidirectional only; not applicable here). Junction temperature range spans –55 °C to +175 °C, and it meets UL 94 V-0 flammability requirements in molded epoxy packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V - defines guaranteed avalanche conduction onset window under 1.0 mA test current |
| VWM | 94.0 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 152 V at 3.9 A - clamping voltage during 10/1000 μs transient, limiting downstream voltage stress |
| PPPM | 600 W - peak pulse power handling capacity, derated above 25 °C per Fig. 2 |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for PCB copper pour design |
| TJ max | +175 °C - maximum junction temperature enabling high-ambient operation in engine bay or power supply modules |
| Leakage @ VWM | <1.0 μA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
Pinout & Package
DO-15 (DO-204AC) axial-leaded package with matte tin-plated leads; no polarity marking for bidirectional configuration. Molded epoxy body meets UL 94 V-0; lead length ≥25.4 mm; diameter 3.3–3.5 mm; weight 0.432 g.

| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Safeguarding Ethernet PHY interfaces and RS-485 transceivers against ESD and induced surges in network infrastructure gear. IC Role / Device Role / Timing Role: Low-capacitance (typ. <50 pF) bidirectional clamp placed differential-mode across data pairs. Use Value: Clamps common-mode transients to ≤152 V while preserving signal rise/fall times due to sub-nanosecond response. | Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters for smart home devices exposed to mains-borne transients. IC Role / Device Role / Timing Role: Parallel-connected TVS across DC output rails to limit transient overshoot during regulator fault conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | DO-214AA package, lower RθJA (50 °C/W vs. 75 °C/W), same VBR/VC specs | Better suited for surface-mount layouts with limited board space; requires SMT reflow profile | Select when automated assembly and compact footprint are prioritized over through-hole serviceability |
| 1.5KE110CA | Same DO-15 package but higher PPPM (1500 W), larger junction area, higher IPPM (10.3 A) | Used where higher surge margin is required (e.g., outdoor telecom cabinets), with trade-off in cost and size | Choose for mission-critical systems needing >2× surge headroom beyond standard 600 W requirement |
Compared with SMBJ110CA and 1.5KE110CA, P6KE110CA-E3/73 offers optimal balance of cost, proven reliability in legacy through-hole designs, and AEC-Q101 qualification - making it preferred for automotive replacement modules and industrial retrofits where DO-15 socket compatibility is mandatory.

FAQ
What is the clamping voltage of P6KE110CA-E3/73 under standard surge conditions?
The P6KE110CA-E3/73 exhibits a maximum clamping voltage (VC) of 152 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 3.9 A. This value is measured per Figure 1 in Vishay document 88369 and ensures downstream circuitry remains within safe voltage limits during transient events. The P6KE110CA-E3/73 maintains this clamping performance across its full operating temperature range.
Is P6KE110CA-E3/73 suitable for automotive applications?
Yes, P6KE110CA-E3/73 is AEC-Q101 qualified per Vishay documentation, confirming its suitability for automotive applications including engine control units, body electronics, and sensor interfaces. Its DO-15 package, –55 °C to +175 °C operating range, and robust surge immunity make P6KE110CA-E3/73 appropriate for under-hood and chassis-mounted systems subject to harsh thermal and electrical environments.
How does the bidirectional nature of P6KE110CA-E3/73 affect its circuit placement?
The bidirectional construction of P6KE110CA-E3/73 eliminates polarity sensitivity, allowing it to be placed across any two nodes requiring symmetrical transient suppression - such as differential signal lines or AC-coupled paths. Unlike unidirectional TVS diodes, P6KE110CA-E3/73 has no cathode marking and functions identically regardless of orientation, simplifying layout and reducing assembly errors in high-mix manufacturing.
What is the standoff voltage rating for P6KE110CA-E3/73, and why does it matter?
P6KE110CA-E3/73 has a standoff voltage (VWM) of 94.0 V, meaning it remains in high-impedance state below this voltage and draws less than 1.0 μA leakage current. This rating ensures reliable operation in 72–90 V nominal systems (e.g., 24 V automotive with load dump) without false triggering or excessive power loss - a critical parameter for maintaining signal fidelity and power efficiency in always-on circuits.
Does P6KE110CA-E3/73 require heatsinking in typical applications?
P6KE110CA-E3/73 does not require external heatsinking for single-event transient suppression due to its short-duration energy absorption (10/1000 μs). However, its thermal resistance from junction to lead (RθJL = 20 °C/W) means PCB copper land area should match DO-15 lead pitch to ensure adequate heat dissipation during repetitive surges. For sustained power dissipation, P6KE110CA-E3/73 relies on natural convection and lead conduction rather than heatsink attachment.
