Product details
Overview
P6KE440C-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 440 V breakdown voltage (VBR min/max = 418 V / 462 V), 600 W peak pulse power (10/1000 µs), and clamps to ≤602 V at 1.00 A peak pulse current - used in automotive sensor protection, industrial I/O interfaces, and telecom line surge suppression.
For engineers reviewing the P6KE440C-E3/54 datasheet, P6KE440C-E3/54 pinout, P6KE440C-E3/54 application, or P6KE440C-E3/54 equivalent, key selection criteria include its bi-directional polarity, 376 V stand-off voltage (VWM), <1.0 µA reverse leakage at VWM, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold (418–462 V), it avalanches rapidly (<1 ns response) to divert surge current away from downstream circuitry. Its bi-directional structure enables symmetric clamping in AC-coupled or floating signal paths without polarity constraints.
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), supporting 5.0 W continuous power dissipation at TL = 75 °C. The glass-passivated junction ensures stable VBR temperature coefficient of +0.110 %/°C and robustness against moisture and mechanical stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 418 V / 462 V at 1.0 mA test current - defines precise avalanche onset window for reliable overvoltage triggering |
| VWM | 376 V - maximum continuous working voltage before leakage exceeds 1.0 µA; sets safe operating margin below breakdown |
| VC @ IPPM | ≤602 V at 1.00 A (10/1000 µs) - clamping voltage limiting worst-case stress on protected ICs or MOSFETs |
| PPPM | 600 W - peak surge energy handling capacity under standardized lightning/surge waveform (IEC 61000-4-5 compliant) |
| IPPM | 1.00 A - maximum non-repetitive surge current the device sustains without degradation |
| TJ max | +175 °C - enables operation in under-hood automotive or high-temperature industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with UL 94 V-0 molded epoxy and matte tin-plated leads |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body, 2.6 mm diameter × 7.6 mm length, RoHS-compliant matte tin plating, rated for solder dip at 275 °C for 10 s. Bi-directional devices have no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction terminals | No functional distinction - either lead serves as input/output; enables placement in AC or floating circuits without orientation check |
Key Features
| Feature | Design Value |

| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-ground) in compact DO-15 footprint |
| AEC-Q101 qualified (HE3 variant); E3 suffix meets JESD 201 Class 1A whisker test | Validated for automotive electronics use including engine control modules and ADAS sensor interfaces |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a/5a) |
| UL 94 V-0 flammability rating | Meets safety requirements for enclosed industrial and telecom equipment housings |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ440CA | Same VBR range (418–462 V), but SMC (DO-214AB) surface-mount package; 600 W rating; lower RθJA (50 °C/W) | Requires PCB rework for SMT layout; better thermal performance in automated assembly | Select SMBJ440CA for space-constrained, high-volume SMT designs where board real estate is limited. |
| 1.5KE440CA | Same VBR and bi-directionality, but higher 1500 W peak power; larger DO-201AD package; 7.0 A IPPM | Over-specified for 600 W needs; suited for higher-energy threat environments (e.g., outdoor telecom cabinets) | Choose 1.5KE440CA only when legacy 1.5 kW surge testing or extended duty-cycle operation is required. |
Compared with SMBJ440CA and 1.5KE440CA, P6KE440C-E3/54 offers optimal balance of cost, axial-leaded through-hole compatibility, and proven AEC-Q101 qualification - making it ideal for automotive and industrial applications where manual assembly, serviceability, and qualification traceability are critical.

FAQ
What is the polarity configuration of P6KE440C-E3/54?
P6KE440C-E3/54 is a bi-directional TVS diode, meaning it functions identically in both directions without cathode/anode distinction. Unlike uni-directional variants (e.g., P6KE440A), it carries no color band marking and is intended for AC-coupled or floating signal paths where polarity reversal may occur - a key design feature confirmed in Vishay's datasheet section "Devices for Bi-Direction Applications".
Does P6KE440C-E3/54 meet automotive qualification standards?
Yes, P6KE440C-E3/54 is RoHS-compliant and qualifies under AEC-Q101 for stress-tested reliability in automotive environments. While the base E3 suffix denotes commercial grade, the HE3 variant (P6KE440C-HE3/54) explicitly carries AEC-Q101 certification per note (1) in the Vishay datasheet - confirming suitability for under-hood and ADAS sensor applications when sourced with HE3 marking.
What is the maximum clamping voltage of P6KE440C-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE440C-E3/54 is 602 V when subjected to a 10/1000 µs waveform at IPPM = 1.00 A. This value is measured per Figure 1 and Table on page 2 of the Vishay datasheet (Doc. #88369) and represents the upper bound of voltage seen by protected circuitry during worst-case transient events.
Can P6KE440C-E3/54 be used in place of P6KE440A?
No - P6KE440C-E3/54 and P6KE440A are functionally distinct: the "C" suffix denotes bi-directional operation, while "A" indicates uni-directional. Substituting one for the other risks improper clamping in AC or bipolar signal paths. The datasheet explicitly states "For bi-directional types, use CA suffix (e.g., P6KE440CA)" - confirming P6KE440C-E3/54 is not a drop-in replacement for uni-directional variants.
What is the thermal resistance specification for P6KE440C-E3/54?
P6KE440C-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W, as specified in the Thermal Characteristics table on page 3 of the Vishay datasheet. These values govern derating curves for continuous power dissipation and must be applied when designing for ambient temperatures above 25 °C or elevated lead temperatures.
