Product details
Overview
P4KE110AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features 110 V breakdown voltage (VBR min/max = 105–116 V), 94.0 V stand-off voltage (VWM), 152 V maximum clamping voltage at 2.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs and sensor interfaces in automotive ECUs.
For engineers reviewing the P4KE110AHE3/54 datasheet, P4KE110AHE3/54 pinout, P4KE110AHE3/54 application, or P4KE110AHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 66 °C/W), DO-41 mechanical dimensions, and real-world protection use cases - all confirmed from Vishay's official document #88365 (Rev. 16-Sep-2021).
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device that conducts above its breakdown threshold to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping performance across repetitive transients.
Designed for 10/1000 µs surge waveforms at 0.01% duty cycle, it supports transient suppression in DC power rails and low-speed signal paths where fast response (<1 ns) and low leakage (<1 µA at 94.0 V) are critical. The DO-41 package provides robust thermal conduction to PCB leads (RθJL = 66 °C/W) and meets UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines precise clamping onset threshold with ±5% tolerance for reliable overvoltage detection |
| VWM | 94.0 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets safe DC bias margin |
| VC @ IPPM | 152 V at 2.6 A peak pulse current - actual clamped voltage seen by protected circuit during 10/1000 µs surge |
| PPPM | 400 W - peak transient power dissipation capability under standardized 10/1000 µs waveform, enabling robust ESD/lightning surge handling |
| IFSM | 40 A - non-repetitive forward surge current rating (8.3 ms half-sine), supporting high-energy inductive switching events |
| TJ max | +175 °C - maximum junction temperature, allowing operation in under-hood automotive environments without derating |
| RθJL | 66 °C/W - thermal resistance from junction to lead, confirming effective heat transfer to PCB traces or heatsinking leads |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads. Meets UL 94 V-0 flammability rating and J-STD-002 solderability standards. Cathode indicated by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; enables unidirectional clamping when cathode is biased positive relative to anode |
| Cathode | Reverse-biased clamping terminal | Marked with color band; connected to higher-potential rail (e.g., VCC or signal line); conducts during overvoltage to shunt current to ground or return path |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance (±5%), low leakage (<1 µA), and long-term reliability under thermal cycling |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| 400 W peak pulse power (10/1000 µs) | Provides immunity against ISO 7637-2 Pulse 1, 2a, 3a/b, and IEC 61000-4-5 Level 3 surges without degradation |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes voltage overshoot during transients, protecting 100 V-rated MOSFETs and microcontrollers with tight VDD margins |
| DO-41 mechanical robustness | Withstands 275 °C solder dip (10 s) per JESD 22-B106 and meets JESD 201 Class 2 whisker resistance (HE3 suffix) |

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 | Surface-mount SMB package (vs. axial DO-41); same VBR range (105–116 V), but lower PPPM = 600 W and higher IPPM = 3.8 A | Requires PCB rework for SMT layout; better suited for high-density consumer boards than through-hole automotive harnesses | Select SMBJ110A only if board space constraints prohibit axial components and thermal management supports SMT pad copper area |
| 1.5KE110A | Same DO-41 package but higher PPPM = 1500 W and larger junction; VC = 177 V at 6.5 A - less tight clamping | Used where higher surge energy (e.g., industrial motor drives) justifies looser voltage control and larger footprint | Choose 1.5KE110A only when system-level testing confirms 177 V clamping does not exceed downstream component ratings |
Compared with SMBJ110A and 1.5KE110A, the P4KE110AHE3/54 offers optimal balance of axial-mount compatibility, AEC-Q101 qualification, 152 V clamping precision, and 400 W surge capacity - making it the preferred choice for cost-sensitive, thermally constrained automotive and industrial designs requiring proven reliability.

FAQ
What is the breakdown voltage tolerance of the P4KE110AHE3/54?
The P4KE110AHE3/54 has a breakdown voltage (VBR) range of 105 V to 116 V at 1.0 mA test current, corresponding to a ±5% tolerance around the nominal 110 V rating. This tight tolerance is achieved via glass passivation and ensures predictable clamping behavior across production lots and temperature ranges from –55 °C to +175 °C.
Is the P4KE110AHE3/54 qualified for automotive applications?
Yes, the P4KE110AHE3/54 carries the HE3 suffix, which denotes AEC-Q101 qualification per Vishay document #88365. This certification covers stress tests including high-temperature reverse bias, temperature cycling, and humidity bias, validating its suitability for under-hood and chassis-mounted automotive electronics such as body control modules and sensor signal conditioning circuits.
What is the maximum clamping voltage of the P4KE110AHE3/54 during a surge event?
The P4KE110AHE3/54 exhibits a maximum clamping voltage (VC) of 152 V at its rated peak pulse current (IPPM) of 2.6 A under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay's datasheet and represents the highest voltage imposed on protected circuitry during worst-case transient conditions.
How does the P4KE110AHE3/54 differ from the P4KE110A-E3/54 variant?
The P4KE110AHE3/54 differs from P4KE110A-E3/54 solely in qualification level: the "HE3" suffix indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas "E3" denotes commercial-grade RoHS compliance only. Both share identical electrical specs, DO-41 packaging, and thermal characteristics - making HE3 the required choice for automotive deployments.
Can the P4KE110AHE3/54 be used in bidirectional configurations?
No, the P4KE110AHE3/54 is strictly unidirectional, as confirmed by its part number suffix "A" and absence of "CA" designation. Bidirectional operation requires CA-suffixed variants (e.g., P4KE110CA). Using P4KE110AHE3/54 in reverse-biased AC applications would result in forward conduction and potential failure due to lack of symmetrical breakdown capability.
