Product details
Overview
P6KE400C-E3/73 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 600 W peak pulse power (10/1000 μs), 342 V stand-off voltage (VWM), 380–420 V breakdown voltage (VBR), and 548 V maximum clamping voltage (VC) at 1.1 A peak pulse current - deployed in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE400C-E3/73 datasheet, P6KE400C-E3/73 pinout, P6KE400C-E3/73 application, or P6KE400C-E3/73 equivalent, key selection criteria include verified bi-directional clamping performance, UL 497B recognition, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and compatibility with 100 A IFSM surge current handling in harsh environments.
Technical Context
This device operates as a voltage-clamped crowbar during transient events, leveraging an avalanche breakdown mechanism to limit reverse and forward surges symmetrically. Its bi-directional structure eliminates polarity dependency, enabling direct placement across AC-coupled or floating differential lines without orientation constraints.
Clamping behavior is defined by two critical points: VWM (342 V) ensures minimal leakage (<1.0 μA) under normal operation, while VC (548 V at IPPM = 1.1 A) guarantees predictable overvoltage limiting during 10/1000 μs transients. Temperature coefficient of VBR is +0.110 %/°C, supporting stable performance across -55 °C to +175 °C junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 342 V - Maximum continuous working voltage before significant leakage; defines safe operating margin for 300 VAC line interfaces. |
| VBR min/max | 380 V / 420 V at 1.0 mA - Confirmed avalanche onset range; ensures reliable triggering within ±5 % tolerance band. |
| VC @ IPPM | 548 V at 1.1 A - Measured clamping voltage under standardized 10/1000 μs surge; determines protected circuit's maximum stress level. |
| PPPM | 600 W - Peak pulse power rating per JEDEC JESD22-A112; supports single-event lightning-induced surges up to 1.1 A. |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pour heatsinking without external heatsink. |
| TJ max | +175 °C - Maximum junction temperature; allows operation in under-hood automotive or high-ambient industrial enclosures. |
| UL Recognition | QVGQ2 file E136766 - Underwriters Laboratories listing for protector classification per UL 497B; required for telecom and industrial safety certification. |
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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed directly at connector entry point to shunt transients before reaching ASIC or MCU input pins. Use Value: Maintains signal integrity below 548 V clamping threshold during 100 V/10 ms load dump events, preventing latch-up or gate oxide damage. |
Use Scenario: Safeguarding RS-485/RS-422 differential data lines in factory automation PLCs exposed to motor switching noise. IC Role / Device Role / Timing Role: Common-mode TVS pair bridging A/B lines to ground, suppressing EFT bursts and surge coupling from adjacent 480 VAC drives. Use Value: Limits common-mode voltage excursion to ≤548 V during 4 kV IEC 61000-4-5 surges, preserving data link uptime and reducing bit error rate. |
| Telecom Line Card Protection | Consumer Power Adapter Input |
Use Scenario: Front-end protection of DSL or PoE-powered Ethernet ports against lightning-induced longitudinal surges on twisted-pair cables. IC Role / Device Role / Timing Role: Primary clamping device across tip/ring or phantom power rails, coordinated with GDT or MOV secondary stages. Use Value: Responds within <1 ns to divert >1.1 A surge current while holding clamped voltage below IC absolute maximum ratings (e.g., PHY transceiver 60 V abs max). |
Use Scenario: Secondary-side transient suppression on DC output rails of wall adapters powering IoT hubs or smart home controllers. IC Role / Device Role / Timing Role: Fast-acting clamp absorbing residual switching spikes and ESD from USB-C or barrel jack hot-plug events. Use Value: Prevents brownout or reset events caused by 300 V microsecond transients, ensuring uninterrupted firmware execution in low-power sleep modes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ400CA | Same VWM (342 V) and VC (548 V), but SMC package (DO-214AB); 600 W rating, lower RθJA (40 °C/W vs. 75 °C/W). | Better thermal performance in high-density layouts; requires footprint change from axial DO-15 to surface-mount SMB. | Select when board space permits SMT placement and higher thermal dissipation is needed for repetitive surge duty cycles. |
| 1.5KE400CA | Same electrical specs (VWM, VBR, VC), but larger DO-201AD package; 1500 W PPPM rating (10/1000 μs), higher IFSM (200 A). | Higher surge endurance for infrequent but extreme events (e.g., outdoor telecom cabinets); heavier mechanical construction. | Choose for mission-critical infrastructure where single-event survivability outweighs size/cost constraints. |
Compared with SMBJ400CA and 1.5KE400CA, the P6KE400C-E3/73 offers optimal balance of axial through-hole manufacturability, UL 497B recognition, and AEC-Q101 qualification in compact DO-15 form - making it preferred for cost-sensitive automotive and industrial control modules requiring proven field reliability.

FAQ
What is the polarity configuration of P6KE400C-E3/73?
The P6KE400C-E3/73 is a bi-directional TVS diode with no cathode marking - both terminals behave identically under positive or negative transient conditions. This eliminates orientation errors during manual assembly and simplifies layout for AC-coupled or floating signal paths. The "C" suffix explicitly denotes bi-directional functionality per Vishay's naming convention.
Does P6KE400C-E3/73 meet AEC-Q101 requirements?
The P6KE400C-E3/73 itself is RoHS-compliant commercial-grade (E3 suffix); however, the HE3-suffixed variant (P6KE400C-HE3/73) is AEC-Q101 qualified. For automotive applications requiring qualification, specify the HE3 version - it undergoes extended stress testing including high-temperature reverse bias and temperature cycling per AEC-Q101 Rev D.
What is the maximum clamping voltage of P6KE400C-E3/73 under surge conditions?
The P6KE400C-E3/73 has a maximum clamping voltage (VC) of 548 V when subjected to a 10/1000 μs waveform at 1.1 A peak pulse current (IPPM). This value is measured per JEDEC JESD22-A112 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Can P6KE400C-E3/73 be used in AC line protection?
Yes - the P6KE400C-E3/73 is rated for 342 V stand-off voltage (VWM), making it suitable for 230 VAC RMS mains-derived circuits with appropriate derating. Its bi-directional nature allows direct placement across live-neutral or live-ground paths, provided system-level coordination with upstream fusing and thermal cutoffs is implemented per IEC 61000-4-5.
What is the thermal resistance from junction to lead for P6KE400C-E3/73?
The P6KE400C-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard test conditions. This enables effective heat transfer to PCB copper pours or chassis mounts, supporting sustained power dissipation up to 5.0 W at TL = 75 °C without forced airflow or external heatsinks.
