Product details
Overview
P6KE27CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 27 V nominal breakdown voltage (VBR = 25.7–28.4 V at 1.0 mA), 37.5 V maximum clamping voltage at 16.0 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE27CAHE3/54 datasheet, P6KE27CAHE3/54 pinout, P6KE27CAHE3/54 application, or P6KE27CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C max junction temperature, low leakage (<1.0 μA at 23.1 V), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM = 23.1 V), but switches to low-impedance conduction within <1 ns when transient voltage exceeds VBR. Its glass-passivated junction ensures stable avalanche characteristics and repeatable clamping performance across surge events.
The P6KE27CAHE3/54 is rated for 600 W peak pulse power with 10/1000 μs waveform, derated linearly above 25 °C ambient per Fig. 2, and supports repetitive surge duty cycles up to 0.01 %. Its thermal resistance (RθJA = 75 °C/W) and RθJL = 20 °C/W enable effective heat dissipation in leaded PCB layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V at 1.0 mA - defines precise avalanche initiation threshold for reliable overvoltage detection |
| VWM | 23.1 V - maximum continuous reverse working voltage before leakage rises significantly |
| VC @ IPPM | 37.5 V at 16.0 A - clamping voltage during worst-case 600 W transient, limiting downstream IC stress |
| IPPM | 16.0 A - peak surge current handled with specified clamping, enabling protection of 24 V industrial buses |
| PPPM | 600 W - standardized 10/1000 μs surge rating, validated for inductive switching and lightning-induced transients |
| TJ max | +175 °C - extended junction temperature range supports under-hood automotive and high-ambient industrial use |
| Leakage @ VWM | <1.0 μA - negligible standby power loss and signal integrity impact in always-on sensor interfaces |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bidirectional operation confirmed by CA 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 |
|---|---|---|---|
| SMBJ24CA | DO-214AA package (SMB), lower 400 W PPPM, VBR = 26.7–29.5 V, VC = 38.9 V @ 10.3 A | Surface-mount only; unsuitable for through-hole legacy designs or high-power radial layouts | Select when board space is constrained and SMT assembly is available; verify thermal pad layout for 400 W derating. |
| 1.5KE27CA | Same DO-15 package, higher 1500 W PPPM, VBR = 25.7–28.4 V, VC = 43.0 V @ 34.9 A | Higher clamping voltage reduces margin for 3.3 V logic; better suited for 48 V industrial buses | Choose for enhanced surge robustness where 43.0 V clamping is acceptable and 1500 W rating is required per IEC 61000-4-5. |
Compared with SMBJ24CA and 1.5KE27CA, the P6KE27CAHE3/54 delivers optimal balance of through-hole manufacturability, 600 W surge handling, and 37.5 V clamping-making it ideal for cost-sensitive automotive and industrial control boards where DO-15 footprint and AEC-Q101 compliance are mandatory.

FAQ
What does the "CA" suffix indicate in P6KE27CAHE3/54?
The "CA" suffix in P6KE27CAHE3/54 denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage clamping in both polarities-ideal for AC signal lines, differential buses like CAN, or ungrounded power rails. Unlike unidirectional variants (e.g., P6KE27A), it has no cathode marking and functions identically regardless of terminal orientation.
Is P6KE27CAHE3/54 suitable for automotive applications?
Yes, P6KE27CAHE3/54 is AEC-Q101 qualified (confirmed by HE3 suffix), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its 175 °C max junction temperature, robust surge handling, and UL 497B recognition meet stringent OEM requirements for under-hood and chassis-mounted systems.
How does the clamping voltage of P6KE27CAHE3/54 compare to its breakdown voltage?
P6KE27CAHE3/54 has a breakdown voltage range of 25.7–28.4 V at 1.0 mA and a maximum clamping voltage of 37.5 V at 16.0 A peak pulse current. This 9.1–11.8 V differential represents the dynamic impedance during surge conduction, ensuring downstream components see limited overvoltage even under full 600 W transient stress.
What is the significance of the "HE3" and "/54" in P6KE27CAHE3/54?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies the preferred packaging code for 13-inch paper tape and reel with 4000 units per reel. Together, they define the exact commercial-grade, automotive-qualified, surface-finish, and logistics configuration of the P6KE27CAHE3/54 device.
Can P6KE27CAHE3/54 replace P6KE27A in a design?
No-P6KE27CAHE3/54 is bidirectional while P6KE27A is unidirectional, with distinct polarity markings and forward voltage behavior. Substituting them requires verifying circuit topology: P6KE27CAHE3/54 works only where symmetrical clamping is needed (e.g., AC lines, differential pairs); P6KE27A is required for DC rails with defined anode/cathode orientation and forward conduction paths.
