Overview
P6KE510-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 485 V minimum breakdown voltage (VBR), 434 V maximum standoff voltage (VWM), 698 V clamping voltage (VC) at 0.86 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive power supply input stages and industrial motor drive control boards.
For engineers reviewing the P6KE510-E3/73 datasheet, P6KE510-E3/73 pinout, P6KE510-E3/73 application, or P6KE510-E3/73 equivalent, key selection criteria include verified clamping performance under 10/1000 µs surge, unidirectional polarity marking, DO-204AC (DO-15) package compatibility with through-hole PCB layouts, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ns) to transient overvoltages while maintaining low incremental surge resistance. Its unidirectional configuration provides reverse-biased clamping only, with cathode-end band marking per JEDEC DO-204AC mechanical standard.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling 5.0 W continuous power dissipation at TL = 75 °C. The device meets UL 497B recognition (QVGQ2) and complies with RoHS Directive 2011/65/EU.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ480A | DO-214AA package; 480 V VWM; 600 W rating; surface-mount, lower profile | Requires SMT reflow process; unsuitable for through-hole legacy designs or high-vibration environments needing axial lead retention | Select when board space is constrained and automated assembly supports SMT; verify thermal pad layout for 5.0 W dissipation. |
| 1.5KE510A | Same DO-204AC package; 485–535 V VBR; 1500 W PPPM; higher surge capacity but larger footprint | Higher clamping voltage (720 V) and slower response due to larger junction area; used where energy levels exceed 600 W | Choose for heavy-industrial applications with frequent high-energy surges (e.g., crane controls), accepting trade-off in response speed. |
Compared with SMBJ480A and 1.5KE510A, the P6KE510-E3/73 delivers optimal balance of through-hole mechanical robustness, automotive qualification, and precise 434 V standoff for 48 V nominal systems - making it preferred for cost-sensitive, high-reliability automotive and industrial power entry designs.

FAQ
What is the clamping voltage of P6KE510-E3/73 under standard surge conditions?
The P6KE510-E3/73 exhibits a maximum clamping voltage (VC) of 698 V when subjected to a 10/1000 µs waveform with a peak pulse current (IPPM) of 0.86 A. This value is measured per the conditions defined in Vishay's Document Number 88369 and represents the upper limit of voltage imposed on the protected circuit during a standardized transient event. Designers must ensure downstream components have voltage ratings exceeding this clamping level.
Is P6KE510-E3/73 suitable for automotive applications?
Yes, the P6KE510-E3/73 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and infotainment power supplies. Its operating junction temperature range of –55 °C to +175 °C, glass-passivated junction, and UL 497B recognition support deployment in under-hood and cabin environments where thermal and reliability demands are stringent.
What does the "E3/73" suffix indicate in P6KE510-E3/73?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance. The "/73" indicates packaging in 73 mm tape-and-reel format per Vishay's ordering convention - distinct from the "/54" variant which uses 54 mm reels. Both share identical electrical and thermal specifications.
How does P6KE510-E3/73 differ from bi-directional TVS diodes like P6KE440CA?
The P6KE510-E3/73 is unidirectional and features a cathode band for polarity identification, allowing it to clamp only reverse-voltage transients while blocking forward current beyond ~3.5 V. In contrast, P6KE440CA is bi-directional with no polarity marking and clamps transients of either polarity - making it suitable for AC lines or differential signal protection where voltage swings occur in both directions.
Can P6KE510-E3/73 be used in parallel for higher surge current handling?
No, P6KE510-E3/73 should not be paralleled without external balancing resistors due to inherent VBR tolerances (±5 %). Mismatched breakdown voltages cause uneven current sharing, risking premature failure of the lower-VBR unit. For higher surge capacity, select a single higher-rated device such as 1.5KE510A rather than attempting parallel connection of P6KE510-E3/73 units.
