Product details
Overview
P6KE250C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for robust overvoltage protection of sensitive electronics. It features a 250 V standoff voltage (VWM), 237–263 V breakdown voltage (VBR) at 1 mA, 344 V maximum clamping voltage (VC) at 1.7 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed across automotive sensor signal lines, industrial I/O ports, and telecom interface protection.
For engineers reviewing the P6KE250C-E3/54 datasheet, P6KE250C-E3/54 pinout, P6KE250C-E3/54 application, or P6KE250C-E3/54 equivalent, key selection criteria include bi-directional clamping symmetry, UL 497B recognition, AEC-Q101 qualification (HE3 variant), thermal resistance (RθJL = 20 °C/W), and compliance with IEC 61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
The P6KE250C-E3/54 operates as a voltage-clamped crowbar device, leveraging an avalanche breakdown mechanism to divert transient energy away from downstream circuitry. Its bi-directional architecture ensures symmetrical clamping in both polarities, with no polarity marking on the package - critical for AC-coupled or differential signal paths where polarity reversal may occur.
It delivers 600 W peak pulse power handling under standardized 10/1000 μs waveform conditions, with clamping performance validated up to 175 °C junction temperature. The device exhibits low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients without affecting normal signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 214 V - maximum continuous reverse operating voltage before clamping initiates; defines safe working margin below breakdown |
| VBR (min/max) | 237 V / 263 V at IT = 1 mA - guaranteed avalanche onset range; ensures predictable turn-on across temperature and unit variation |
| VC @ IPPM | 344 V at 1.7 A - maximum clamped voltage during 10/1000 μs surge; directly limits stress on protected ICs |
| PPPM | 600 W - peak transient power dissipation capability; determines survivability against high-energy surges |
| ID @ VWM | 1.0 μA - ultra-low leakage at rated standoff voltage; preserves signal integrity and minimizes standby power loss |
| TJ max. | +175 °C - extended junction temperature rating enables use in under-hood automotive and high-ambient industrial environments |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports reliable power derating without external heatsinking |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Bi-directional configuration - no cathode band or polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (reversible) | Bi-directional avalanche junction | Either lead serves as anode or cathode depending on transient polarity; symmetric clamping behavior in both directions |
| Lead 1 / Lead 2 | Current path terminals | Leads conduct surge current bidirectionally; no internal asymmetry - requires no orientation during PCB placement |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ250CA | Same VWM (214 V) and VC (344 V), but SMC (DO-214AB) package - 1.5× larger footprint, lower RθJA (35 vs. 75 °C/W) | Better thermal performance in high-duty-cycle surge environments; requires PCB re-layout due to different pad geometry | Select when higher average power handling or improved thermal margin is required; not drop-in compatible |
| 1.5KE250CA | Same electrical specs (VWM, VBR, VC), but higher PPPM (1500 W) and larger DO-201AD package; VF = 5.0 V at 50 A | Higher single-pulse energy absorption; suited for infrequent but extreme transients (e.g., utility grid coupling) | Choose for mission-critical infrastructure where worst-case surge margin exceeds 600 W; adds board space and cost |
Compared with SMBJ250CA and 1.5KE250CA, the P6KE250C-E3/54 offers optimal balance of compact DO-15 form factor, certified AEC-Q101 reliability (HE3), and UL 497B recognition - making it preferred for space-constrained automotive and telecom edge devices where regulatory alignment and layout efficiency are prioritized.

Does the P6KE250C-E3/54 meet automotive reliability standards?
Yes - the P6KE250C-E3/54 is RoHS-compliant and offered in HE3 suffix variant (P6KE250CHE3/54) that is fully AEC-Q101 qualified. This includes stress testing for temperature cycling, high-temperature operating life, and mechanical shock, confirming suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of the P6KE250C-E3/54 under surge conditions?
The P6KE250C-E3/54 has a maximum clamping voltage (VC) of 344 V at 1.7 A peak pulse current (IPPM), measured using the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is guaranteed across the full operating temperature range.
How does the P6KE250C-E3/54 differ from the uni-directional P6KE250A-E3/54?
The P6KE250C-E3/54 is bi-directional (denoted by "C" suffix), providing symmetrical clamping for both positive and negative transients, whereas the P6KE250A-E3/54 is uni-directional with a cathode band marking and forward voltage drop (~5.0 V). The "C" version eliminates polarity dependency, making it ideal for AC or floating signal lines.
