Product details
Overview
P6KE480A-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for overvoltage protection of sensitive electronics. It features a 456 V to 504 V breakdown voltage (VBR), 408 V maximum standoff voltage (VWM), 658 V clamping voltage (VC) at 0.91 A peak pulse current, and 600 W peak pulse power dissipation with 10/1000 μs waveform - deployed in industrial power supply input stages and automotive ECU front-end protection.
For engineers reviewing the P6KE480A-E3/73 datasheet, P6KE480A-E3/73 pinout, P6KE480A-E3/73 application, or P6KE480A-E3/73 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, and AEC-Q101 qualification status for high-reliability design validation.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM = 408 V, then avalanches sharply at VBR = 456–504 V (tested at 1.0 mA), limiting transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response (<1 ns).
Thermal performance is defined by RθJL = 20 °C/W and RθJA = 75 °C/W; power derating begins above TA = 25 °C per Fig. 2, with full 5.0 W dissipation only at TL = 75 °C on infinite heatsink. Junction temperature range spans –55 °C to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 456 V / 504 V at 1.0 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 408 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 658 V at 0.91 A (10/1000 μs) - clamping voltage that determines protected circuit's worst-case stress level |
| PPPM | 600 W - peak surge power handling capacity under standardized lightning/surge waveform |
| IFSM | 100 A (8.3 ms half-sine) - single-pulse forward surge rating for inductive turn-off events |
| TJ max. | +175 °C - enables operation in under-hood automotive or high-ambient industrial environments |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports PCB-level heat sinking without external heatsink |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Cathode indicated by color band; RoHS-compliant (E3 suffix), commercial grade.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection to protected circuit ground | Current path during reverse-biased transient clamping; must connect to lowest-impedance ground plane |
| Cathode | High-side connection to line or signal being protected | Marked end; connects to input rail or signal trace upstream of sensitive ICs/MOSFETs |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance (±5 %) and low leakage (<1.0 μA) across temperature and lifetime |

Use Scenario: Surge suppression on -48 V telecom power distribution boards exposed to induced transients from nearby switching equipment. IC Role / Device Role / Timing Role: Reverse-biased protection element absorbing common-mode surges coupled onto power rails via shared grounding. Use Value: 408 V VWM allows safe operation under nominal -48 V with margin; 658 V VC protects -48 V DC-DC modules with 75 V absolute max rating. |
Use Scenario: DC link protection in solar string inverters where PV array open-circuit voltage reaches 1000 V, requiring staged clamping. IC Role / Device Role / Timing Role: Secondary-stage TVS used after MOVs to handle residual fast-rising transients not absorbed by bulk suppressors. Use Value: Fast <1 ns response complements slower MOVs; 600 W rating handles repetitive switching transients in 50/60 Hz grid-tied operation. |
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 | DO-214AA package; 480 V VBR min (456–504 V same), 600 W rating, but lower IPPM = 0.85 A at VC = 658 V | Surface-mount alternative for space-constrained PCBs; requires rework of footprint and thermal relief | Select SMBJ480A only if board layout mandates SMD and thermal management supports lower RθJA = 40 °C/W |
| P6KE440A | Lower VBR (418–462 V), VWM = 376 V, VC = 602 V at 1.00 A - 56 V lower clamping than P6KE480A-E3/73 | Better suited for 380–400 VAC systems where tighter clamping margin is critical | Choose P6KE440A when system VDC max is ≤420 V and clamping headroom must be minimized |

FAQ
What is the breakdown voltage range for P6KE480A-E3/73?
The P6KE480A-E3/73 has a guaranteed breakdown voltage (VBR) range of 456 V to 504 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight ±5 % tolerance ensures consistent avalanche triggering across production lots and temperature extremes, critical for predictable clamping behavior in 400 V+ systems where P6KE480A-E3/73 is commonly deployed.
Is P6KE480A-E3/73 suitable for automotive applications?
P6KE480A-E3/73 is the commercial-grade version (E3 suffix) and is not AEC-Q101 qualified. For automotive use, the HE3-suffixed variant (e.g., P6KE480AHE3/73) must be selected - it undergoes extended stress testing including temperature cycling, humidity bias, and mechanical shock per AEC-Q101. P6KE480A-E3/73 itself is rated for industrial and telecom environments only.
What is the maximum clamping voltage of P6KE480A-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE480A-E3/73 is 658 V at 0.91 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value represents the upper limit of voltage seen by downstream components during worst-case surge events and is validated per IEC 61000-4-5 testing methodology - a key parameter used to verify compatibility with 600 V-rated MOSFETs and capacitors in P6KE480A-E3/73-protected circuits.
How does thermal derating affect P6KE480A-E3/73 power dissipation?
P6KE480A-E3/73 has a nominal power dissipation (PD) of 5.0 W at TL = 75 °C on infinite heatsink, but derates linearly above TA = 25 °C per Figure 2 in the datasheet. At 100 °C ambient, its usable power drops to ~3.3 W; at 125 °C, it falls to ~2.0 W. Engineers must apply this curve when designing for enclosed enclosures or high-temperature zones - failure to do so risks thermal runaway during sustained overvoltage events in P6KE480A-E3/73 installations.
What is the lead finish and solderability specification for P6KE480A-E3/73?
P6KE480A-E3/73 features matte tin-plated leads compliant with J-STD-002 (solderability) and JESD 22-B102 (solder heat resistance). It withstands solder dip at 275 °C for up to 10 seconds per JESD 22-B106 and passes JESD 201 Class 1A whisker testing. These specifications ensure reliable through-hole reflow and wave soldering in high-volume manufacturing - essential for consistent joint integrity in P6KE480A-E3/73-based power supply assemblies.
