Product details
Overview
P6KE540-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 600 W peak pulse power with 10/1000 μs waveform, 459 V stand-off voltage (VWM), 513–567 V breakdown voltage (VBR), and 740 V maximum clamping voltage (VC) at 0.81 A peak pulse current - deployed for overvoltage protection of power rails and signal lines in industrial power supplies and automotive ECUs.
For engineers reviewing the P6KE540-E3/54 datasheet, P6KE540-E3/54 pinout, P6KE540-E3/54 application, or P6KE540-E3/54 equivalent, key selection criteria include verified clamping performance under 10/1000 μs surge, thermal resistance (RθJL = 20 °C/W), RoHS-compliant matte tin plating, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its clamping behavior is defined by VC = 740 V at IPPM = 0.81 A (10/1000 μs), with VBR specified at 1 mA test current and temperature coefficient of +0.110 %/°C.
Designed for single-pulse transient suppression only, it features 175 °C maximum junction temperature, 5.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and complies with JESD 22-B106 solder dip (275 °C, 10 s). Polarity is marked by cathode band; no marking on bi-directional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 459 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VBR min/max | 513 V / 567 V at 1 mA - ensures reliable avalanche conduction onset across production lot and temperature |
| VC @ IPPM | 740 V at 0.81 A (10/1000 μs) - defines worst-case protected circuit voltage during surge event |
| PPPM | 600 W - peak transient power handling capability per single 10/1000 μs pulse |
| RθJL | 20 °C/W - enables thermal design margin when mounted to PCB copper pour or lead frame |
| TJ max | 175 °C - supports operation in under-hood automotive environments and high-ambient industrial enclosures |

IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp surges before they reach upstream DC/DC converter ICs. Use Value: Limits transient voltage to ≤740 V, preventing damage to 60 V-rated MOSFETs and gate drivers while maintaining system uptime. | Use Scenario: 12 V battery-supplied engine control unit subjected to ISO 7637-2 pulse 5a (load dump up to 60 V). IC Role / Device Role / Timing Role: Primary clamping device on main power input, positioned upstream of LDO regulators and microcontroller power pins. Use Value: Absorbs 600 W surge energy within 1 ms, holding downstream voltage below 740 V to avoid latch-up or permanent failure of 5 V logic circuits. |
| Telecom Line Interface Protection | Renewable Energy Inverter DC Link |
Use Scenario: Secondary-side 48 V telecom power feed line connecting remote radio units, subject to lightning-induced surges. IC Role / Device Role / Timing Role: Standoff-rated TVS on DC output rail of isolated DC/DC converter, referenced to local ground plane.

IC Role / Device Role / Timing Role: Overvoltage limiter on high-voltage DC bus, connected anode-to-ground to protect IGBT gate drivers and sensing amplifiers. Use Value: Withstands 459 V continuous operation and clamps 10/1000 μs surges to 740 V, enabling use with 800 V-class power semiconductors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ440A | DO-214AA package; 440 V VWM, 488–539 V VBR, 644 V VC @ 0.93 A; 600 W rating | Lower clamping voltage but reduced standoff margin; surface-mount only | Select when board space is constrained and 440 V standoff suffices |
| 1.5KE540A | DO-201AD package; identical VWM/VBR/VC specs; 1500 W rating; higher IPPM (1.62 A) | Higher surge capacity but larger footprint and higher RθJA (60 °C/W) | Select when legacy through-hole layout allows larger case and higher single-pulse energy is required |
Compared with SMBJ440A and 1.5KE540A, P6KE540-E3/54 offers optimal balance of 459 V standoff, 740 V clamping, DO-15 axial form factor, and AEC-Q101 qualification - making it preferred for cost-sensitive, space-constrained automotive and industrial designs requiring proven reliability.

FAQ
What is the maximum clamping voltage of the P6KE540-E3/54 under standard test conditions?
The P6KE540-E3/54 has a maximum clamping voltage (VC) of 740 V when subjected to a 10/1000 μs waveform at peak pulse current (IPPM) of 0.81 A. This value is measured per JEDEC standards and reflects worst-case voltage seen by downstream circuitry during surge events. The P6KE540-E3/54 maintains this clamping performance across its rated operating temperature range.
Is the P6KE540-E3/54 suitable for automotive applications?
Yes, the P6KE540-E3/54 is AEC-Q101 qualified per the Vishay datasheet (Document Number 88369, Note 1), confirming its suitability for automotive applications such as engine control units, body control modules, and infotainment power inputs. The P6KE540-E3/54 meets stress testing requirements for temperature cycling, humidity, and mechanical shock relevant to under-hood and cabin environments.
What does the "E3/54" suffix indicate in P6KE540-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance. The "/54" indicates packaging in 13-inch paper tape and reel with 4000 units per reel, per Vishay's ordering information table. The P6KE540-E3/54 is not AEC-Q101 qualified - that requires the "HE3" suffix variant (e.g., P6KE540AHE3/54).
How does the P6KE540-E3/54 compare to bi-directional TVS diodes like P6KE440CA?
The P6KE540-E3/54 is unidirectional and optimized for DC rail protection with cathode-to-line orientation; P6KE440CA is bi-directional and used for AC or floating signal lines. The P6KE540-E3/54 offers higher VWM (459 V vs. 376 V) and VBR (513–567 V vs. 418–462 V), but cannot suppress negative-going transients. Use P6KE540-E3/54 where polarity is fixed and standoff voltage is critical.
What is the thermal resistance from junction to lead (RθJL) for the P6KE540-E3/54?
The P6KE540-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, as specified in the Vishay datasheet (Document Number 88369, Thermal Characteristics table). This value enables accurate thermal modeling when the device is soldered to PCB copper or mounted with short lead lengths, supporting reliable operation up to 175 °C junction temperature. The P6KE540-E3/54 benefits from direct lead conduction for heat dissipation.
