Product details
Overview
P6KE27C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features a 27 V breakdown voltage (VBR min/max = 25.7–28.4 V at 1.0 mA), 23.1 V stand-off voltage (VWM), 37.5 V maximum clamping voltage (VC) at 16.0 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE27C-E3/54 datasheet, P6KE27C-E3/54 pinout, P6KE27C-E3/54 application, or P6KE27C-E3/54 equivalent, key selection criteria include bi-directional clamping capability, UL 94 V-0 rated epoxy package, AEC-Q101 qualification (via HE3 variant), thermal resistance (RθJL = 20 °C/W), and low leakage (<1.0 µA at VWM) - critical for low-power sensor and CAN bus line protection.
Technical Context
The P6KE27C-E3/54 operates as a bi-directional avalanche diode, symmetrically clamping both positive and negative transients without polarity marking. Its glass-passivated junction enables fast response time (<1.0 ns) and stable breakdown characteristics across -55 °C to +175 °C operating temperature range.
It delivers 600 W peak pulse power under standardized 10/1000 µs waveform, with clamping voltage tightly specified at 37.5 V (max) when subjected to 16.0 A IPPM. Thermal performance is defined by RθJL = 20 °C/W and RθJA = 75 °C/W, supporting reliable operation on PCBs with moderate copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V at 1.0 mA - defines precise avalanche onset threshold for bidirectional transient suppression |
| VWM | 23.1 V - maximum continuous working voltage before leakage exceeds 1.0 µA; sets safe operating margin below breakdown |
| VC @ IPPM | 37.5 V at 16.0 A - clamped voltage seen by protected circuit during worst-case 10/1000 µs surge |
| PPPM | 600 W - peak transient energy handling capacity; determines survivability against lightning or ESD-like events |
| IPPM | 16.0 A - maximum non-repetitive surge current supported; informs fuse/circuit breaker coordination |
| TJ max | +175 °C - high junction temperature rating enables use in under-hood automotive or industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94 V-0 molded epoxy and matte tin leads |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body, no polarity marking for bi-directional operation. Leads are matte tin plated, solderable per J-STD-002 and JESD 22-B102; meets JESD 201 Class 1A whisker test (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | No functional distinction between leads; either terminal serves as cathode or anode depending on transient polarity |
| Lead 1 | Terminal connection | Directly bonded to silicon die; forms low-inductance path for surge current return |
| Lead 2 | Terminal connection | Electrically identical to Lead 1; enables mounting in either orientation on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable, repeatable avalanche characteristics over lifetime and temperature cycling |
| 600 W peak pulse power (10/1000 µs) | Supports robust protection against IEC 61000-4-5 Level 4 surges without derating in standard layouts |
| AEC-Q101 qualified (HE3 variant) | Validated for automotive electronics including engine control, body modules, and ADAS sensor interfaces |
| UL 94 V-0 flammability rating | Molding compound self-extinguishes under flame exposure - required for safety-critical industrial enclosures |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., relay coil flyback, ESD) |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | DO-214AA package; lower 24 V VBR; 600 W rating; higher IPPM (24.9 A); lower VC (38.9 V) | Suitable for space-constrained SMT designs; not axial-leaded; requires rework of footprint and assembly process | Select when board real estate is limited and surface-mount assembly is available. |
| 1.5KE27C | Same DO-204AC package; identical VBR/VWM/VC; 1500 W rating (10/1000 µs); higher IPPM (41.2 A); larger thermal mass | Used where higher surge endurance is required (e.g., outdoor telecom cabinets); heavier leadframe increases weight and cost | Choose for mission-critical infrastructure needing extended surge margin beyond 600 W. |
Compared with SMBJ24CA and 1.5KE27C, the P6KE27C-E3/54 offers optimal balance of axial-leaded compatibility, AEC-Q101 readiness (via HE3), and cost-effective 600 W protection - making it ideal for high-volume automotive and industrial control modules where through-hole assembly remains standard.

FAQ
What is the breakdown voltage tolerance for P6KE27C-E3/54?
The P6KE27C-E3/54 has a specified breakdown voltage range of 25.7 V to 28.4 V at 1.0 mA test current, representing ±10 % tolerance around the nominal 27 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports predictable system-level surge margin design without overspecifying downstream components.
Is P6KE27C-E3/54 suitable for automotive applications?
Yes - the P6KE27C-E3/54 is RoHS-compliant and offered in AEC-Q101-qualified variant (P6KE27CHE3/54). Its -55 °C to +175 °C operating range, glass-passivated junction, and UL 94 V-0 package meet core requirements for under-hood and cabin electronics, including engine control sensors and infotainment power rails.
How does the clamping voltage of P6KE27C-E3/54 compare to its stand-off voltage?
The P6KE27C-E3/54 has a stand-off voltage (VWM) of 23.1 V and a maximum clamping voltage (VC) of 37.5 V at 16.0 A. This 14.4 V differential defines the protective window: normal operation stays safely below 23.1 V, while transients are limited to ≤37.5 V - sufficient to protect most 24 V-rated ICs and interface circuits.
Does P6KE27C-E3/54 have polarity markings?
No - the P6KE27C-E3/54 is a bi-directional TVS diode and carries no color band or marking. Its symmetrical construction allows installation in either orientation across protected lines, simplifying assembly and eliminating risk of reverse placement errors in high-mix manufacturing.
What is the thermal resistance of P6KE27C-E3/54, and how does it affect layout?
The P6KE27C-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W. To maintain reliability under repetitive surges, PCB traces connected to its leads should be ≥0.5 mm wide and ≥10 mm long to act as heat sinks; this minimizes junction temperature rise and avoids derating of peak pulse power capability.
