Product details
Overview
P6KA27AHE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection of sensitive electronics. It features a 25.7–28.4 V breakdown voltage (VBR), 23.1 V stand-off voltage (VWM), 37.5 V clamping voltage at 16.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power line and sensor interface protection.
For engineers reviewing the P6KA27AHE3/54 datasheet, P6KA27AHE3/54 pinout, P6KA27AHE3/54 application, or P6KA27AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, DO-15 package compatibility, and verified clamping performance under repetitive surge conditions.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable clamping under high-temperature operation up to TJ = 185 °C and withstands solder dip at 275 °C for 10 s per JESD 22-B106. Its unidirectional polarity and low incremental surge resistance ensure fast response (<1 ns) and minimal voltage overshoot during transients induced by inductive switching.
The device operates within a -65 °C to +185 °C junction/storage temperature range and exhibits a VBR temperature coefficient of 0.096 %/°C - enabling predictable performance drift compensation in automotive and industrial environments where thermal cycling is severe.
Key Specifications

|---|---|
| VBR (min/max) | 25.7 V / 28.4 V - ensures reliable triggering above normal operating voltage while avoiding false trips on ripple or tolerance stack-up |
| VWM | 23.1 V - maximum continuous reverse working voltage compatible with 24 V nominal automotive systems |
| VC @ IPPM | 37.5 V - clamps 16.0 A transient to safe levels for downstream MOSFETs or ICs rated ≤40 V |
| PPPM | 600 W - sustains 10/1000 μs surges common in ISO 7637-2 Pulse 1 & 2a automotive tests |
| IFSM | 75 A - handles 8.3 ms half-sine surge events without bond wire failure |
| TJ max. | +185 °C - supports under-hood placement and AEC-Q101 qualification for automotive grade reliability |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 9.5 mm body length and RoHS-compliant matte tin plating |
Pinout & Package
DO-204AC (DO-15) molded epoxy package with axial leads; cathode denoted by color band on body; matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102 solderability standards.

| Cathode | Reverse-biased terminal during normal operation | Connected to protected line (e.g., 24 V rail); blocks leakage until VBR exceeded |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, mechanical shock, and humidity testing per JEDEC standard |
| 185 °C junction capability | Enables direct mounting near heat sources (e.g., engine control units) without derating penalties |
| 600 W peak pulse power | Meets ISO 7637-2 Pulse 1 (inductive load dump) and Pulse 2a (supply interruption) immunity requirements |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes stress on downstream components during ESD or lightning-induced transients |
| HE3 suffix | Meets JESD 201 Class 2 whisker resistance - critical for long-life automotive and industrial deployments |
Applications

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 | Lower VBR (26.7–29.5 V), same DO-214AA package, 600 W rating, but only rated to 150 °C TJ | Lacks AEC-Q101 qualification and 185 °C capability - unsuitable for under-hood automotive use | Select when cost sensitivity outweighs high-temp reliability; verify thermal margin in enclosure design |
| 1.5KE27A | Higher VC (45.7 V), larger DO-201AD package, same 600 W rating, but not AEC-Q101 qualified | Clamps less tightly - may exceed voltage limits of 36 V-rated downstream ICs during worst-case transients | Acceptable for industrial AC/DC supplies where space allows larger package and thermal derating is feasible |
Compared with SMBJ24A and 1.5KE27A, the P6KA27AHE3/54 delivers superior high-temperature stability (185 °C vs. 150 °C), tighter clamping (37.5 V vs. ≥45 V), and automotive-grade qualification - making it the preferred choice for mission-critical 24 V system protection where reliability and compact DO-15 form factor are essential.

FAQ
What is the clamping voltage of the P6KA27AHE3/54 at its rated peak pulse current?
The P6KA27AHE3/54 has a maximum clamping voltage (VC) of 37.5 V at 16.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components rated for ≤40 V remain within safe operating limits during surge events. The P6KA27AHE3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KA27AHE3/54 qualified for automotive applications?
Yes, the P6KA27AHE3/54 is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and other high-reliability automotive applications. Its HE3 suffix confirms compliance with JESD 201 Class 2 whisker resistance, and the device meets solderability standards per J-STD-002 and JESD 22-B102 - all verified in Vishay's official qualification report for the P6KAxxA family.
What is the difference between P6KA27AHE3/54 and P6KA27HE3/54?
The P6KA27AHE3/54 features a tighter breakdown voltage range (25.7–28.4 V) versus the broader P6KA27HE3/54 (24.3–29.7 V), resulting in more consistent clamping behavior and reduced unit-to-unit variation. Both share identical package (DO-15), power rating (600 W), and AEC-Q101 qualification, but the "A" suffix denotes enhanced VBR tolerance - critical for designs requiring precise threshold control in safety-critical systems.
Can the P6KA27AHE3/54 be used in bidirectional configurations?
No, the P6KA27AHE3/54 is unidirectional only, as confirmed in the Vishay datasheet under FEATURES and PRIMARY CHARACTERISTICS. It must be oriented with cathode toward the protected line and anode to ground. For bidirectional protection, a separate device such as the P6SMB27CA or dual-diode array would be required - the P6KA27AHE3/54 does not support reverse-polarity clamping.
What is the maximum leakage current of the P6KA27AHE3/54 at its stand-off voltage?
The P6KA27AHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 23.1 V stand-off voltage (VWM) and 25 °C ambient temperature. At elevated temperature (TJ = 150 °C), leakage remains ≤5.0 μA - ensuring minimal power loss and signal interference in always-on sensor or telemetry circuits where low quiescent current is essential.
