Product details
Overview
P6KE27-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 27 V breakdown voltage (VBR = 25.7–28.4 V at 1.0 mA), 37.5 V maximum clamping voltage (VC) at 16.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive body electronics, industrial sensor interfaces, and 24 V PLC I/O modules.
For engineers reviewing the P6KE27-E3/54 datasheet, P6KE27-E3/54 pinout, P6KE27-E3/54 application, or P6KE27-E3/54 equivalent, key selection criteria include its DO-15 package compatibility, unidirectional polarity with cathode band marking, 23.1 V stand-off voltage (VWM), and AEC-Q101 qualification for automotive-grade reliability under transient surge conditions.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at 23.1 V).
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient); derating begins above 25 °C ambient, with full power (5.0 W) only sustainable at TL ≤ 75 °C per Fig. 5. The device fails short-circuit under catastrophic overload, enabling fuse/breaker coordination.
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 clamping onset |
| VWM | 23.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 37.5 V at 16.0 A - clamping voltage during 10/1000 µs surge, limiting protected IC stress to safe levels |
| PPPM | 600 W - peak transient energy absorption capability without degradation under standardized surge waveform |
| IFSM | 100 A - withstands 8.3 ms half-sine surge, supporting robust protection against inductive switch-off spikes |
| TJ max. | +175 °C - enables operation in under-hood automotive environments and high-temperature industrial enclosures |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94 V-0 molded epoxy housing |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy-molded case with cathode band marking on one end. Matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode (banded end) | Reverse-biased clamping terminal | Connected to protected line (e.g., 24 V rail); avalanche conduction occurs when line voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5 %) and low leakage (<1 µA) across temperature and lifetime |
| 600 W peak pulse power (10/1000 µs) | Handles high-energy transients from relay coil decay or ESD events without parametric shift |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| UL 94 V-0 flammability rating | Mold compound self-extinguishes under flame exposure, meeting safety requirements for enclosed systems |
| Low clamping ratio (VC/VBR ≈ 1.35) | Minimizes overvoltage stress on downstream MOSFETs or microcontrollers during surge events |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |

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; 24 V VBR; 38.9 V VC @ 15.4 A; 600 W rating | Surface-mount footprint; lower profile; higher thermal resistance (RθJA = 110 °C/W) | Select SMBJ24A for space-constrained PCBs where reflow assembly is preferred over through-hole mounting. |
| 1.5KE27A | Same DO-15 package; identical VBR range (25.7–28.4 V); 37.5 V VC; 1500 W rating | Higher peak power handling; larger package volume; not AEC-Q101 qualified | Choose 1.5KE27A when system-level surge testing requires >600 W margin, and automotive qualification is not required. |
Compared with SMBJ24A and 1.5KE27A, P6KE27-E3/54 offers optimal balance of AEC-Q101 compliance, through-hole manufacturability, and validated 600 W surge performance in the widely adopted DO-15 form factor - making it ideal for cost-sensitive, high-reliability automotive and industrial designs.

FAQ
What is the breakdown voltage tolerance for P6KE27-E3/54?
The P6KE27-E3/54 has a specified breakdown voltage range of 25.7 V to 28.4 V at 1.0 mA test current, corresponding to a ±5 % tolerance around the nominal 27 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable system-level surge margin calculations in designs using P6KE27-E3/54.
Is P6KE27-E3/54 RoHS compliant and halogen-free?
Yes, P6KE27-E3/54 carries the "E3" suffix indicating full RoHS compliance per Directive 2011/65/EU and halogen-free status per JEDEC JS709A. The device uses matte tin-plated leads and UL 94 V-0 epoxy molding compound - verified in Vishay's material declarations and supported by certificate of compliance documentation for P6KE27-E3/54.
How does P6KE27-E3/54 differ from bi-directional variants like P6KE27CA?
P6KE27-E3/54 is unidirectional with cathode band marking and conducts only in reverse bias above VBR; P6KE27CA is bi-directional with no polarity marking and clamps symmetrically in both directions. The unidirectional P6KE27-E3/54 provides lower leakage (<1.0 µA at 23.1 V) and is preferred for DC rail protection, whereas P6KE27CA suits AC-coupled or floating signal line applications - both share identical VBR, VC, and PPPM ratings.
What is the maximum operating temperature for P6KE27-E3/54?
P6KE27-E3/54 has a maximum junction temperature (TJ) rating of +175 °C and an operating ambient range of –55 °C to +175 °C. Derating of peak pulse power begins above 25 °C ambient per Figure 2, and continuous power dissipation must be limited to 5.0 W only when lead temperature (TL) is held at or below 75 °C - critical for thermal design validation in sealed enclosures using P6KE27-E3/54.
Can P6KE27-E3/54 be used in place of P6KE24A or P6KE30A?
No - P6KE27-E3/54 is not a direct substitute for P6KE24A (24 V nominal) or P6KE30A (30 V nominal), as each part has distinct VBR, VWM, and VC values optimized for specific rail voltages. Substituting alters clamping margin and risk of premature conduction or insufficient protection. System-level validation is required if changing to P6KE27-E3/54, especially in 24 V applications where its 23.1 V VWM provides 0.9 V headroom.
