Product details
Overview
P6KE110HE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for overvoltage protection of sensitive electronics. It features a 105 V minimum breakdown voltage (VBR), 94.0 V maximum stand-off voltage (VWM), 152 V clamping voltage (VC) at 3.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial I/O modules.
For engineers reviewing the P6KE110HE3/73 datasheet, P6KE110HE3/73 pinout, P6KE110HE3/73 application, or P6KE110HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 0.107 %/°C VBR temperature coefficient, and verified performance under repetitive surge duty cycles up to 0.01 %.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (94.0 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins against ESD and inductive switching spikes.
The device is rated for 100 A non-repetitive forward surge current (IFSM) and exhibits 3.5 V max forward voltage at 50 A - confirming suitability for DC power rail clamping where forward conduction may occur during asymmetrical transients. Thermal resistance is specified at RθJL = 20 °C/W (junction-to-lead), enabling reliable operation without heatsinking in standard PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 94.0 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC bias margin for protected line. |
| VBR (min/max) | 105 V / 116 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 152 V at 3.9 A - Clamped voltage during 10/1000 µs surge; determines worst-case stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling capability; supports robust protection against lightning-induced surges per IEC 61000-4-5. |
| IFSM | 100 A - Single half-sine surge rating (8.3 ms); validates resilience to motor-commutation spikes in automotive body control modules. |
| TJ max | 175 °C - Maximum junction temperature; enables deployment in under-hood automotive environments with minimal derating. |
| Temp. Coeff. | 0.107 %/°C - Low VBR drift with temperature; maintains consistent clamping threshold across -55 °C to +175 °C range. |
Pinout & Package

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump transients (up to 60 V for 400 ms) and alternator ripple. IC Role / Device Role / Timing Role: Shunt clamping element placed between power input and ground, responding within <1 ns to suppress overvoltage before IC damage occurs. Use Value: Withstands 100 A IFSM and 600 W PPPM, enabling single-device compliance with ISO 7637-2 Pulse 5a without external fusing or series impedance. |
Use Scenario: Safeguarding analog outputs (4–20 mA loops) and digital I/O (RS-485, CAN) in PLC modules exposed to field wiring surges. IC Role / Device Role / Timing Role: Bidirectional-capable protection (via companion CA variant) or uni-directional rail clamp; placed adjacent to connector entry point. Use Value: 152 V clamping voltage limits stress on 16 V-rated op-amps and 3.3 V/5 V interface ICs - validated for IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity testing. |
| Consumer Power Adapter Input Stage | Telecom Line Card Surge Protection |
|
Use Scenario: Secondary-side DC output protection in AC/DC adapters subject to capacitor discharge transients and hot-plug events. IC Role / Device Role / Timing Role: Uni-directional TVS connected between regulated 5 V/12 V output and GND, absorbing energy from capacitive coupling or feedback loop instability. Use Value: 94.0 V VWM allows safe operation with 12 V nominal rails while maintaining 11 V margin to VBR - preventing false triggering during normal regulation ripple. |
Use Scenario: Primary protection for Ethernet PHYs and xDSL line drivers against lightning-induced common-mode surges entering via RJ-45 jacks. IC Role / Device Role / Timing Role: Paired with gas discharge tube (GDT) in hybrid protection scheme; P6KE110HE3/73 handles fast-rising edge (<1 µs) while GDT handles high total energy. Use Value: Fast response and low VC ensure sub-100 ns clamping - preserving signal integrity on 100BASE-TX and VDSL2 channels during surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-E3/52 (Vishay) | Same VWM/VBR/VC specs but in SMB (DO-214AA) surface-mount package; 600 W rating retained; lower RθJA (50 °C/W vs. 75 °C/W). | Preferred for automated SMT assembly and space-constrained boards; unsuitable for through-hole or high-vibration mechanical mounting. | Select SMBJ110A-E3/52 when board real estate is limited and reflow compatibility is required; P6KE110HE3/73 remains optimal for manual assembly, repairability, and lead-forming flexibility. |
| 1.5KE110A (ON Semiconductor) | Identical DO-204AC package and electrical specs (VWM = 94 V, VC = 152 V), but not AEC-Q101 qualified; higher max ID (5 µA vs. 1 µA) at VWM. | Acceptable for commercial/industrial use but excluded from automotive BOMs requiring AEC-Q101 certification. | Choose 1.5KE110A only for cost-sensitive non-automotive designs where qualification traceability is not mandated; P6KE110HE3/73 delivers certified reliability for Tier-1 automotive supply chains. |
Compared with SMBJ110A-E3/52 and 1.5KE110A, P6KE110HE3/73 uniquely combines AEC-Q101 qualification, axial-leaded DO-204AC form factor, and 1 µA max leakage at VWM - making it the preferred choice for automotive power distribution modules and field-serviceable industrial controllers requiring mechanical robustness and qualification assurance.

FAQ
What is the clamping voltage of P6KE110HE3/73 and how is it measured?
The clamping voltage (VC) of P6KE110HE3/73 is 152 V, measured at 3.9 A peak pulse current using a 10/1000 µs waveform per IEC 61000-4-5. This value represents the maximum voltage seen across the device during standardized surge testing and directly determines the overvoltage stress imposed on protected components. The P6KE110HE3/73 achieves this clamping level while maintaining low incremental surge resistance, ensuring effective energy diversion without excessive voltage overshoot.
Is P6KE110HE3/73 suitable for automotive applications?
Yes, P6KE110HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments with operating temperatures from –55 °C to +175 °C. Its HE3 suffix confirms compliance with JESD 201 Class 2 whisker resistance and RoHS requirements - making P6KE110HE3/73 appropriate for engine control modules, body electronics, and ADAS sensor interfaces where reliability and qualification traceability are mandatory.
How does the P6KE110HE3/73 differ from the P6KE110A variant?
The P6KE110HE3/73 differs from P6KE110A primarily in qualification and plating: the HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas P6KE110A is commercial-grade only. Both share identical electrical parameters (VWM = 94.0 V, VBR = 105–116 V, VC = 152 V), but P6KE110HE3/73 is required for automotive production and offers enhanced long-term reliability in vibration-prone, high-temperature deployments.
What is the maximum reverse leakage current for P6KE110HE3/73 at its stand-off voltage?
The maximum reverse leakage current (ID) for P6KE110HE3/73 is 1.0 µA at its stand-off voltage (VWM = 94.0 V) and TA = 25 °C. This low leakage ensures minimal power loss in standby mode and prevents unintended loading of high-impedance circuits such as sensor bias networks or microcontroller wake-up inputs - a critical design advantage confirmed in the Vishay 88369 datasheet for P6KE110HE3/73.
Can P6KE110HE3/73 be used in bi-directional protection configurations?
No, P6KE110HE3/73 is a uni-directional TVS diode, indicated by the "A" suffix and cathode band marking. For bi-directional applications - such as AC line protection or differential bus clamping (e.g., RS-485) - the companion part P6KE110CA must be used. The P6KE110HE3/73's internal structure supports conduction only from cathode to anode during overvoltage events, making it unsuitable for symmetrical surge suppression without external circuitry.
