Product details
Overview
P6KE440CA-E3/54 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 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 to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6KE440CA-E3/54 datasheet, P6KE440CA-E3/54 pinout, P6KE440CA-E3/54 application, or P6KE440CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C max junction temperature, low leakage (<1.0 μA at 376 V), and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its bidirectional CA construction. Its 600 W surge rating is defined under standardized 10/1000 μs waveform conditions with 0.01 % duty cycle, and thermal performance is governed by RθJL = 20 °C/W and RθJA = 75 °C/W.
Clamping behavior is characterized by VC = 602 V at IPPM = 1.00 A, with VWM = 376 V and maximum reverse leakage of 1.0 μA. Temperature coefficient of VBR is +0.110 %/°C, indicating stable breakdown voltage drift across operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 418 V / 462 V at 1.0 mA test current - defines guaranteed avalanche onset window for bidirectional transient suppression |
| VWM | 376 V - maximum continuous working voltage before significant leakage; sets safe operating margin below breakdown |
| VC @ IPPM | 602 V at 1.00 A - clamped voltage during worst-case 10/1000 μs surge; determines protected circuit's peak stress level |
| PPPM | 600 W - peak pulse power handling per single transient; enables protection against lightning-induced surges and inductive switching spikes |
| IPPM | 1.00 A - peak pulse current corresponding to VC; used with VC to calculate effective clamping impedance (~602 Ω) |
| TJ max | +175 °C - maximum junction temperature; supports operation in high-ambient environments like engine compartments or enclosed power modules |
| Leakage @ VWM | ≤1.0 μA - ensures minimal standby power loss and signal integrity on high-impedance lines such as sensor inputs or communication buses |
Pinout & Package
Package: DO-15 (DO-204AC), 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. No polarity marking - bidirectional symmetry eliminates cathode/anode orientation concerns during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminal | Either lead serves as input/output path; no directional bias required - simplifies PCB layout and eliminates orientation errors |
| Lead 1 / Lead 2 | Current-carrying terminal pair | Handles full surge current path; thermal resistance RθJL = 20 °C/W measured from junction to lead - requires adequate copper pour for heat dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Enables stable, repeatable avalanche characteristics over lifetime and temperature; resists moisture ingress and surface degradation |
| 600 W peak pulse power (10/1000 μs) | Supports robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-line) without derating in typical board layouts |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive electronics use including body control modules and infotainment power rails - meets stress-test requirements for temperature cycling, HTRB, and ESD |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns response); critical for safeguarding sub-20 V logic-level MOSFET gates |
| UL 94 V-0 molding compound | Prevents flame propagation in fault conditions - satisfies safety compliance for industrial equipment enclosures and power supply housings |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ440CA | Same VBR range (418–462 V) but SMC (DO-214AB) package; 600 W rating, lower RθJA (50 °C/W) than DO-15 | Preferred for automated SMT assembly and higher-power density layouts; not axial-leaded | Select SMBJ440CA when board space is constrained and reflow compatibility is required over through-hole mounting. |
| 1.5KE440CA | Same VBR/VC specs but 1500 W rating (10/1000 μs); larger DO-201AD package; higher IPPM (2.25 A) | Suitable for higher-energy threat environments (e.g., AC mains input stages) where 600 W is insufficient | Choose 1.5KE440CA only if system-level surge testing exceeds IEC 61000-4-5 Level 4 or requires >1.5× energy margin. |
Compared with SMBJ440CA and 1.5KE440CA, P6KE440CA-E3/54 offers optimal cost-performance balance for mid-energy transients in through-hole designs, with verified AEC-Q101 qualification and UL 94 V-0 compliance - making it preferred for automotive and industrial control boards where axial lead reliability and qualification traceability are mandatory.

FAQ
What is the breakdown voltage tolerance for P6KE440CA-E3/54?
The P6KE440CA-E3/54 has a specified breakdown voltage range of 418 V to 462 V at 1.0 mA test current, representing ±5 % tolerance around the nominal 440 V rating. This tight VBR window ensures consistent clamping onset across production lots and supports predictable system-level surge margin calculations in designs using P6KE440CA-E3/54.
Is P6KE440CA-E3/54 suitable for automotive applications?
Yes, P6KE440CA-E3/54 is AEC-Q101 qualified per the Vishay datasheet revision 27-Sep-2021, confirming compliance with stress tests including high-temperature reverse bias, temperature cycling, and ESD. Its DO-15 package, 175 °C max junction temperature, and 1.0 μA leakage at 376 V make P6KE440CA-E3/54 appropriate for under-hood and body electronics where environmental robustness is required.
How does the clamping voltage of P6KE440CA-E3/54 compare to its breakdown voltage?
P6KE440CA-E3/54 clamps to 602 V at 1.00 A peak pulse current, which is approximately 37 % above its minimum breakdown voltage of 418 V. This VC/VBR ratio reflects the device's low dynamic impedance under surge conditions and confirms its effectiveness in limiting transient overvoltage to a known, bounded level - a critical parameter when protecting 440 V-class power stages with P6KE440CA-E3/54.
What is the maximum allowable reverse leakage current for P6KE440CA-E3/54?
The maximum reverse leakage current for P6KE440CA-E3/54 is 1.0 μA at its stand-off voltage of 376 V and ambient temperature of 25 °C. This ultra-low leakage preserves signal integrity on high-impedance nodes and minimizes standby power loss - essential for battery-operated sensors and always-on control circuits where P6KE440CA-E3/54 is deployed.
Does P6KE440CA-E3/54 have polarity markings on the package?
No, P6KE440CA-E3/54 has no polarity markings because it is a bidirectional TVS diode - both terminals are functionally identical and interchangeable. Unlike unidirectional variants (e.g., P6KE440A), the CA suffix indicates symmetrical avalanche behavior, eliminating cathode band identification and simplifying PCB assembly for P6KE440CA-E3/54.
