Product details
Overview
P6KE480A-E3/54 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 480 V breakdown voltage (VBR = 456–504 V at IT = 1.0 mA), 408 V maximum standoff voltage (VWM), 658 V clamping voltage (VC) at 0.91 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the P6KE480A-E3/54 datasheet, P6KE480A-E3/54 pinout, P6KE480A-E3/54 application, or P6KE480A-E3/54 equivalent, this device is selected for high-voltage industrial power supply input stages, telecom line protection, and automotive body control modules where robust 600 W surge handling and DO-15 package compatibility with legacy through-hole layouts are required.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal conditions it presents <1 µA leakage at 408 V, then rapidly avalanches when transient voltage exceeds VBR, limiting downstream voltage to ≤658 V at 0.91 A. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
Designed for single-pulse and low-duty-cycle (<0.01 %) repetitive surge events, it delivers fast response time (<1.0 ns), thermal resistance of 20 °C/W (junction-to-lead), and operates across –55 °C to +175 °C junction temperature range - validated per AEC-Q101 for automotive-grade reliability in non-safety-critical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 456 V / 504 V at 1.0 mA test current - defines precise avalanche initiation threshold for predictable clamping onset |
| VWM | 408 V maximum - ensures reliable blocking during normal 400 V DC rail operation without leakage-induced power loss |
| VC @ IPPM | 658 V at 0.91 A - limits protected circuit voltage during 10/1000 µs surge, enabling downstream component survival |
| PPPM | 600 W - sustains high-energy transients common in industrial motor drives and telecom central office equipment |
| IFSM | 100 A (8.3 ms half-sine) - withstands short-duration inrush or fault currents without catastrophic failure |
| TJ max. | +175 °C - supports operation in high-ambient environments such as engine bay electronics or enclosed power converters |
| RθJL | 20 °C/W - enables effective heat dissipation into PCB copper when mounted with ≥0.375″ lead length |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by color band on body end.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ480A | Same VWM/VBR/VC specs but in SMB (DO-214AA) surface-mount package; 600 W rating retained | Requires PCB redesign for SMT layout; better suited for space-constrained telecom modules | Select when board real estate is limited and reflow assembly is preferred over through-hole wave soldering |
| 1.5KE480A | Higher 1500 W peak pulse power; same DO-15 package; VBR = 456–504 V, VC = 658 V at 2.27 A | Delivers greater surge margin for utility meter or solar inverter DC link protection | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and higher energy absorption is mandated |
Compared with SMBJ480A and 1.5KE480A, the P6KE480A-E3/54 offers optimal balance of proven through-hole manufacturability, AEC-Q101 qualification, and cost-effective 600 W protection - making it ideal for high-volume industrial controls where legacy DO-15 footprint compatibility and automotive-grade reliability are jointly required.

FAQ
What is the maximum clamping voltage of the P6KE480A-E3/54 under standard surge conditions?
The P6KE480A-E3/54 has a maximum clamping voltage (VC) of 658 V when subjected to its rated peak pulse current of 0.91 A using the 10/1000 µs waveform. This value is measured per JEDEC standards and guarantees that downstream components see no more than 658 V during surge events - critical for protecting 600 V-rated capacitors and rectifiers in 400 V DC systems. The P6KE480A-E3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KE480A-E3/54 suitable for automotive applications?
Yes, the P6KE480A-E3/54 is AEC-Q101 qualified (as confirmed by the "E3" suffix and Vishay documentation), making it suitable for automotive body electronics such as door modules, lighting controllers, and HVAC systems. It operates reliably from –55 °C to +175 °C and withstands 100 A surge current (8.3 ms half-sine), meeting ISO 7637-2 Pulse 5a requirements. The P6KE480A-E3/54 is not intended for safety-critical ADAS or powertrain functions unless explicitly validated by the end customer.
How does the P6KE480A-E3/54 differ from bidirectional TVS diodes like P6KE440CA?
The P6KE480A-E3/54 is unidirectional and blocks only positive voltage transients relative to ground, with a cathode marking for correct orientation. In contrast, P6KE440CA is bidirectional and protects against both polarities - but its maximum VBR is 440 V, making it unsuitable as a direct replacement for the 480 V-rated P6KE480A-E3/54. The P6KE480A-E3/54's 408 V VWM also provides tighter margin for 400 V DC systems than the 376 V VWM of P6KE440CA.
What is the thermal resistance and how does it affect PCB layout for the P6KE480A-E3/54?
The P6KE480A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, meaning each watt of power dissipated raises the junction temperature 20 °C above the lead temperature. To maintain safe operation under repetitive surges, leads should be soldered with ≥0.375″ (9.5 mm) length to act as heat sinks, and copper pour connected to both leads improves heat spreading. The P6KE480A-E3/54's RθJA is 75 °C/W, so ambient cooling remains essential for sustained power dissipation.
Can the P6KE480A-E3/54 be used in parallel for higher surge current handling?
No - the P6KE480A-E3/54 is not recommended for parallel operation due to mismatch in VBR tolerance (±5 %) and dynamic impedance, which causes uneven current sharing and potential thermal runaway. For higher surge capability, select a single higher-rated device such as 1.5KE480A (1500 W) or verify derating curves in the Vishay datasheet. The P6KE480A-E3/54 is characterized and tested as a standalone protection element.
