Product details
Overview
P4KE27CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 27 V breakdown voltage (VBR = 25.7–28.4 V at 1.0 mA), 23.1 V stand-off voltage (VWM), and clamps transients to ≤37.5 V at 10.7 A peak pulse current (10/1000 μs waveform), making it suitable for protecting MOSFETs and signal lines in automotive power supplies.
For engineers reviewing the P4KE27CHE3/54 datasheet, P4KE27CHE3/54 pinout, P4KE27CHE3/54 application, or P4KE27CHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 400 W peak pulse power rating, low 0.096 %/°C temperature coefficient of VBR, and DO-41 leaded package compatibility with through-hole PCB assembly.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ps typical) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients. Its unidirectional polarity-marked by a cathode band-ensures asymmetric conduction with forward voltage drop of 3.5 V at 25 A.
The device operates across -55 °C to +175 °C junction temperature range and is rated for 1.5 W steady-state power dissipation on an infinite heatsink at 75 °C. Thermal resistance is 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient, LLead = 10 mm), supporting reliable thermal performance in compact industrial and automotive layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V at 1.0 mA - defines precise clamping onset threshold under standardized test conditions |
| VWM | 23.1 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | ≤37.5 V at 10.7 A - peak clamped voltage during 10/1000 μs transient, directly limiting stress on downstream ICs |
| PPPM | 400 W - peak pulse power handling capability per single 10/1000 μs surge, validated at 0.01 % duty cycle |
| IFSM | 40 A - non-repetitive forward surge current rating (8.3 ms half-sine), critical for inrush and fault-current immunity |
| TJ max. | +175 °C - enables operation in under-hood automotive environments and high-temperature industrial enclosures |
| Temp. Coeff. (VBR) | +0.096 %/°C - ensures predictable VBR drift over temperature, simplifying margining in wide-range designs |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode identified by color band; RoHS-compliant and AEC-Q101 qualified (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connects to lower-potential side (e.g., ground or return path); conducts during positive transients when cathode is biased higher |
| Cathode | Reverse-biased clamping terminal | Marked end; connects to protected line (e.g., 24 V rail); initiates avalanche breakdown above VWM to shunt surge energy |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repetitive surge stress |
| AEC-Q101 qualification | Validated for automotive-grade deployment including engine control units, body electronics, and ADAS power rails |
| 400 W peak pulse power (10/1000 μs) | Provides industry-standard surge immunity against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3/4 threats |
| Low clamping ratio (VC/VBR ≈ 1.32) | Minimizes voltage overshoot during clamping, reducing risk of latch-up or damage to 3.3 V/5 V logic interfaces |
| UL 94 V-0 molding compound | Ensures flame-retardant enclosure integrity in safety-critical industrial and transportation systems |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Surface-mount SMB package; 24 V VWM, 38.9 V VC @ 10.3 A; 600 W PPPM | Higher power density but requires rework for SMT layout; lacks AEC-Q101 qualification in standard grade | Select when board space is constrained and automotive qualification is not required. |
| 1.5KE27A | Same DO-41 package; 27 V VBR; 400 W PPPM; no AEC-Q101 qualification; commercial-grade only (E3 suffix) | Lower cost but unsuitable for automotive production; identical electrical specs except qualification status | Select for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated. |
Compared with SMBJ24A and 1.5KE27A, P4KE27CHE3/54 uniquely combines AEC-Q101 qualification, DO-41 through-hole compatibility, and verified 175 °C operation-making it the preferred choice for automotive Tier-1 suppliers requiring traceable, high-reliability surge protection without SMT requalification.

FAQ
What is the meaning of the 'HE3' suffix in P4KE27CHE3/54?
The HE3 suffix in P4KE27CHE3/54 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. This distinguishes it from the commercial-grade E3 variant and confirms suitability for automotive production use, including under-hood applications where vibration and thermal cycling are present.
Can P4KE27CHE3/54 be used in bidirectional protection circuits?
No, P4KE27CHE3/54 is a unidirectional TVS diode, as confirmed by its part number ending in 'A' (not 'CA') and cathode band marking. For bidirectional protection, Vishay specifies variants like P4KE27CA; using P4KE27CHE3/54 in reverse-biased AC applications would result in forward conduction and potential failure.
What is the maximum allowable lead temperature during soldering for P4KE27CHE3/54?
The maximum solder dip temperature for P4KE27CHE3/54 is 275 °C for up to 10 seconds, per JESD 22-B106. This limit applies to wave or hand-soldering processes; exceeding it risks delamination of the epoxy mold or degradation of the glass-passivated junction.
How does the 0.096 %/°C temperature coefficient affect P4KE27CHE3/54's clamping behavior?
The +0.096 %/°C temperature coefficient means VBR increases by approximately 27 mV per °C rise in junction temperature. At 125 °C, VBR rises to ~29.5 V, shifting the clamping threshold upward-designers must verify that the elevated VC remains below the protected circuit's absolute maximum rating across the full operating range.
Is P4KE27CHE3/54 compatible with lead-free reflow processes?
P4KE27CHE3/54 is not intended for reflow soldering; it is a through-hole DO-41 device designed for wave, selective, or hand-soldering. Its 275 °C/10 s solder dip rating aligns with lead-free wave processes, but peak reflow temperatures (typically >260 °C for >60 s) exceed its thermal endurance and may damage the package or junction.
