Product details
Overview
P6KE27HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 600 W peak pulse power (10/1000 μs), 25.7 V minimum breakdown voltage (VBR), 37.5 V maximum clamping voltage (VC) at 16.0 A peak pulse current (IPPM), and AEC-Q101 qualification for automotive-grade reliability - deployed in ECU power input stages and sensor interface protection.
For engineers reviewing the P6KE27HE3/54 datasheet, P6KE27HE3/54 pinout, P6KE27HE3/54 application, or P6KE27HE3/54 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, RoHS-compliant matte tin plating, and AEC-Q101 qualification status for automotive use cases.
Technical Context
The P6KE27HE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to transient overvoltages. Its unidirectional configuration requires cathode-band orientation toward the protected line's positive rail, and it conducts only during reverse-biased overvoltage events - not during normal forward operation.
Clamping behavior is defined by two critical points: VBR ≥ 25.7 V at 1.0 mA test current ensures reliable standoff up to 23.1 V (VWM), while VC ≤ 37.5 V at IPPM = 16.0 A guarantees safe voltage limiting during 600 W surges. Thermal derating follows a linear curve above 25 °C ambient, with full power rated only at TL ≤ 75 °C per Fig. 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 23.1 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA; sets upper limit for normal DC rail operation |
| VBR (min) | 25.7 V at 1.0 mA - guaranteed avalanche initiation threshold; ensures predictable turn-on margin above VWM |
| VC | 37.5 V at 16.0 A - maximum clamped voltage during 10/1000 μs surge; defines worst-case stress on downstream ICs |
| PPPM | 600 W - peak pulse power handling capability; supports IEC 61000-4-5 Level 4 (4 kV) surge testing when properly mounted |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; enables direct PCB copper pour heat sinking without external heatsink |
| TJ max | +175 °C - maximum junction temperature; allows operation in under-hood automotive environments with local heating |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements including HTGB, HTRB, and temperature cycling |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case with UL 94 V-0 rating. Cathode identified by color band on body; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Forward conduction terminal | Connected to ground or low-side reference; carries surge current to ground during clamping event |
| Cathode (banded lead) | Reverse-biased avalanche terminal | Connected to protected line (e.g., 24 V supply rail); initiates clamping when voltage exceeds VBR |
Key Features

| 600 W peak pulse power (10/1000 μs) | Supports industrial-level surge immunity (IEC 61000-4-5) without external series impedance |
| AEC-Q101 qualification | Validated for automotive powertrain and body control modules requiring zero-failure field reliability |
| Matte tin-plated leads | Ensures solderability per J-STD-002 and whisker resistance per JESD 201 Class 2 (HE3 suffix) |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns rise time), improving protection margin |
Applications
| Automotive Body Control Module (BCM) Power Input | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: 12 V/24 V battery-supplied BCM exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power rail upstream of LDOs and microcontrollers. Use Value: Limits transient voltage to ≤37.5 V during 600 W surges, preventing latch-up or gate oxide damage in downstream PMICs. |

Use Scenario: -48 V DC feed line powering remote radio units, exposed to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: First-stage protection device on DC input before DC/DC converter and PoE controller. Use Value: Clamps 10/1000 μs surges to safe levels while surviving repeated exposure due to robust glass-passivated junction. |
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 | DO-214AA package; lower 600 W rating but higher IPPM (27.3 A at 24 V); VC = 38.9 V | Suitable for space-constrained SMT layouts; less effective thermal dissipation than axial DO-15 in high-ambient environments | Select SMBJ24A when board real estate is limited and reflow compatibility is required; verify RθJA meets thermal budget. |
| 1.5KE27A | Same DO-204AC package; higher 1500 W rating but larger footprint; VC = 41.5 V at 36.2 A | Better suited for high-energy surges (e.g., AC mains coupling), but over-spec'd for typical 24 V automotive transients | Choose 1.5KE27A only if system-level surge testing exceeds IEC 61000-4-5 Level 4; adds unnecessary cost and size for standard BCM use. |
Compared with SMBJ24A and 1.5KE27A, the P6KE27HE3/54 delivers optimal balance of AEC-Q101 qualification, axial through-hole mounting robustness, and precise 23.1 V–37.5 V clamping window for 24 V automotive systems - making it the preferred choice where reliability, thermal management, and qualification compliance are prioritized over raw power rating or SMT compatibility.

FAQ
What is the clamping voltage of P6KE27HE3/54 at its rated peak pulse current?
The P6KE27HE3/54 has a maximum clamping voltage (VC) of 37.5 V when subjected to its rated peak pulse current of 16.0 A using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings. The P6KE27HE3/54 maintains this clamping performance consistently across its qualified operating temperature range.
Is P6KE27HE3/54 suitable for automotive applications?
Yes, the P6KE27HE3/54 is AEC-Q101 qualified, meaning it has passed rigorous stress tests including high-temperature reverse bias, high-temperature operating life, and temperature cycling - all required for automotive under-hood and cabin electronics. Its DO-204AC package, matte tin plating (JESD 201 Class 2), and 175 °C maximum junction temperature make the P6KE27HE3/54 appropriate for engine control units, body control modules, and HVAC systems where reliability under thermal and electrical stress is mandatory.
How does the HE3 suffix differ from the E3 suffix in P6KE27HE3/54?
The HE3 suffix in P6KE27HE3/54 indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas the E3 suffix denotes commercial-grade RoHS compliance only (JESD 201 Class 1A). Both share identical electrical parameters and DO-204AC packaging, but the HE3 version undergoes additional automotive-specific qualification testing and tighter process controls. For automotive designs requiring formal qualification evidence, the P6KE27HE3/54 - not P6KE27E3/54 - must be specified and sourced.
What is the standoff voltage (VWM) of P6KE27HE3/54, and why does it matter?
The standoff voltage (VWM) of P6KE27HE3/54 is 23.1 V - the maximum continuous reverse voltage it can block without exceeding 1.0 μA leakage current. This parameter ensures the P6KE27HE3/54 remains non-conductive during normal operation of a 24 V nominal system, avoiding power loss or false triggering. Selecting a VWM correctly below the system's maximum steady-state voltage (with margin) is essential to prevent premature conduction while retaining sufficient headroom for clamping action during transients.
Can P6KE27HE3/54 be used in bi-directional protection circuits?
No, the P6KE27HE3/54 is a uni-directional TVS diode, identifiable by its cathode band marking and specified breakdown behavior only in reverse bias. For bi-directional protection (e.g., AC lines or differential signal pairs), Vishay offers the CA-suffixed variant P6KE27CA, which provides symmetrical clamping in both polarities. Using the P6KE27HE3/54 in a bi-directional configuration would result in forward conduction and potential failure during negative transients - always match polarity type to circuit topology.
