Product details
Overview
P6KE400A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 400 V breakdown voltage (VBR = 380–420 V at 1.0 mA), 342 V stand-off voltage (VWM), 548 V maximum clamping voltage at 1.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the P6KE400A-E3/54 datasheet, P6KE400A-E3/54 pinout, P6KE400A-E3/54 application, or P6KE400A-E3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge, DO-15 mechanical dimensions, and AEC-Q101 qualification status for automotive-grade design validation.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 342 V, it avalanches to limit transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 µA at VWM), while thermal resistance RθJA = 75 °C/W and RθJL = 20 °C/W define its power dissipation limits under pulsed and steady-state conditions.
The device sustains 100 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits 0.110 %/°C temperature coefficient of VBR, enabling predictable clamping across -55 °C to +175 °C operating range. Its fast response time (<1.0 ns) and low incremental surge resistance ensure effective suppression of ESD, lightning-induced surges, and inductive switching transients.
Key Specifications

Use Scenario: 24 V battery-fed ECUs exposed to load dump (ISO 16750-2) and jump-start transients up to 60 V. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between power rail and chassis ground to clamp surges before they reach LDOs and microcontrollers. Use Value: Limits peak voltage to ≤548 V during 1.1 A surge, preventing damage to downstream 40 V-rated MOSFETs and analog front-ends. |
Use Scenario: 4–20 mA current loop sensors in factory automation subject to cable-coupled EFT (IEC 61000-4-4) and surge events. IC Role / Device Role / Timing Role: Bidirectional-capable but used unidirectionally across sensor output to ground, suppressing common-mode transients on twisted-pair wiring. Use Value: Sub-1 ns response ensures clamping occurs before sensitive op-amps or ADC inputs saturate or latch up. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drive Inputs |
|
Use Scenario: -48 V telecom rectifier outputs feeding base station boards, vulnerable to lightning-induced surges on long feeder lines. IC Role / Device Role / Timing Role: Primary-level TVS on input bulk capacitor node, absorbing energy before it propagates to DC/DC converters. Use Value: 600 W rating supports multi-pulse surge endurance required for outdoor cabinet installations per GR-1089-CORE. |
Use Scenario: AC motor drive boards in washing machines where relay switching induces >1 kV transients on 300 V DC bus. IC Role / Device Role / Timing Role: Mounted across DC link capacitors to suppress commutation spikes and protect IGBT gate drivers. Use Value: 175 °C max junction temperature allows placement near heat-generating power stages without thermal derating penalties. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ400A | Same VBR range (380–420 V), but SMC (DO-214AB) surface-mount package; 600 W rating; lower RθJA = 40 °C/W | Requires PCB rework for SMT layout; better thermal performance in space-constrained designs | Select SMBJ400A when board real estate is limited and thermal management via copper pour is feasible. |
| 1.5KE400A | Same VBR/VC specs, but higher 1.5 kW peak power; larger DO-201AD package; 5.0 W steady-state rating vs. 5.0 W for P6KE400A-E3/54 | Overqualified for 600 W surge needs; adds mechanical height and cost where not needed | Choose 1.5KE400A only if future-proofing for higher-energy transients or legacy DO-201AD footprint compatibility is required. |
Compared with SMBJ400A and 1.5KE400A, P6KE400A-E3/54 offers optimal balance of proven DO-15 through-hole reliability, AEC-Q101 qualification, and cost-effective 600 W surge handling - making it preferred for automotive and industrial applications where serviceability and thermal margin are prioritized over miniaturization.

FAQ
What is the breakdown voltage tolerance for P6KE400A-E3/54?
The P6KE400A-E3/54 has a specified breakdown voltage range of 380 V to 420 V at 1.0 mA test current, representing ±5% tolerance around the nominal 400 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports reliable overvoltage threshold design in 342 V working voltage systems. The value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's Document Number 88369.
Is P6KE400A-E3/54 suitable for bidirectional transient suppression?
No, P6KE400A-E3/54 is a unidirectional TVS diode - it protects only against reverse-polarity transients on the cathode side. For bidirectional protection, Vishay specifies the CA-suffixed variant (e.g., P6KE400CA). The "A" suffix denotes unidirectional configuration, and the color band marks the cathode. Using P6KE400A-E3/54 in bidirectional applications risks failure during positive-going transients.
What is the maximum clamping voltage of P6KE400A-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE400A-E3/54 is 548 V, measured at 1.1 A peak pulse current using the standard 10/1000 µs waveform. This value represents the worst-case voltage seen by downstream components during a full-rated surge event and is critical for ensuring protected ICs remain within their absolute maximum ratings. It is guaranteed per datasheet Table on page 2 of Document 88369.
Does P6KE400A-E3/54 meet automotive qualification standards?
Yes, P6KE400A-E3/54 is AEC-Q101 qualified - explicitly noted in the Vishay datasheet revision 27-Sep-2021 (Document Number 88369) under "Notes" and "Ratings and Characteristics Curves". This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress testing (HAST), confirming suitability for automotive powertrain, body, and infotainment modules.
What is the thermal resistance of P6KE400A-E3/54, and how does it affect power handling?
P6KE400A-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W. These values define its steady-state and pulsed thermal limits: at 25 °C ambient, its 5.0 W power dissipation rating derates linearly above 25 °C, reaching zero at 175 °C junction temperature. Proper lead length (≥9.5 mm) and PCB copper area are essential to maintain safe thermal margins during repetitive surges.
