Product details
Overview
P4KE480A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for clamping high-energy transients on power and signal lines. It features 400 W peak pulse power (10/1000 μs), 408 V stand-off voltage (VWM), 456–504 V breakdown voltage (VBR at 1 mA), 658 V maximum clamping voltage (VC at 0.61 A), and operates from –55 °C to +175 °C. It protects MOSFETs and ICs in industrial power supplies against inductive switching surges.
For engineers reviewing the P4KE480A-E3/54 datasheet, P4KE480A-E3/54 pinout, P4KE480A-E3/54 application, or P4KE480A-E3/54 equivalent, key selection criteria include clamping voltage margin relative to system rail, peak pulse current capability under 10/1000 μs waveform, thermal resistance (RθJL = 66 °C/W), AEC-Q101 qualification status, and DO-41 lead-form compatibility with legacy through-hole layouts.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity-marked by a cathode band-enables asymmetric clamping, allowing reverse-biased operation up to 408 V before breakdown, with forward conduction limited by VF ≈ 5.0 V at 25 A.
The device complies with JEDEC JESD22-B106 (solder dip: 275 °C max, 10 s) and JESD201 Class 1A whisker testing (E3 suffix). Thermal derating follows a linear curve above 25 °C ambient, with full 1.5 W power dissipation only at TL = 75 °C on infinite heatsink per Figure 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 408 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets upper limit for protected line voltage. |
| VBR (min/max) | 456 V / 504 V at 1 mA - Confirmed breakdown range ensures reliable triggering across process variation and temperature. |
| VC @ IPPM | 658 V at 0.61 A - Clamping voltage during 10/1000 μs surge defines worst-case overvoltage seen by downstream circuitry. |
| PPPM | 400 W - Peak pulse power rating determines survivability of standardized lightning/surge waveforms (IEC 61000-4-5). |
| TJ max | +175 °C - Enables use in high-temperature environments such as automotive engine compartments or enclosed industrial enclosures. |
| RθJL | 66 °C/W - Junction-to-lead thermal resistance governs self-heating during repetitive surges; critical for duty-cycle-limited applications. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; cathode indicated by color band on body end. Leads conform to J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connects to lower-potential side of protected line; conducts during positive transients when cathode is biased higher. |
| Cathode | Reverse-biased clamping terminal | Marked end; connects to higher-potential side (e.g., VIN rail); initiates avalanche breakdown above VWM. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable VBR tolerance (±5 % typical) and long-term reliability under humidity and thermal cycling. |
| 400 W peak pulse power (10/1000 μs) | Supports Level 4 IEC 61000-4-5 surge immunity (4 kV line-to-line, 2 kV line-to-earth) without degradation. |
| AEC-Q101 qualified (E3 suffix) | Validated for automotive powertrain and body electronics where extended temperature and lifetime requirements apply. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., relay coil flyback), improving protection margin. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module |
|---|---|
Use Scenario: Protects DC input stage of 48 V industrial SMPS against load dump and inductive switching spikes from contactors or solenoids. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and ground to clamp reverse transients before they reach rectifier bridge or controller IC. Use Value: Withstands 400 W surges while limiting clamped voltage to ≤658 V, preserving 800 V-rated MOSFETs and reducing need for oversized input capacitors. | Use Scenario: Shields LIN bus transceivers and microcontroller I/O pins in door module ECUs from battery voltage transients during jump-start or alternator load dump. IC Role / Device Role / Timing Role: Standoff-rated TVS on 12 V supply rail upstream of LDO regulators, triggered only during >408 V events. Use Value: AEC-Q101 qualification and 175 °C TJ max ensure compliance with ISO 7637-2 Pulse 5a/b requirements in under-hood environments. |
| Telecom AC-DC Adapter Input | Consumer Appliance Motor Drive |
Use Scenario: Guards primary-side rectifier and controller IC in universal-input (90–264 VAC) adapters against differential-mode surges from mains grid switching. IC Role / Device Role / Timing Role: Unidirectional TVS connected anode-to-ground, cathode-to-bridge output, absorbing energy before it reaches bulk capacitor and PWM IC. Use Value: 658 V clamping voltage provides ≥20 % margin above 540 V peak of 380 VAC input, preventing premature failure of 650 V MOSFETs. | Use Scenario: Safeguards gate drivers and half-bridge MOSFETs in washing machine motor inverters from flyback voltage generated by brushed motor commutation. IC Role / Device Role / Timing Role: TVS placed across DC bus rails (VBUS–GND) to clamp regenerative spikes during rapid deceleration. Use Value: 400 W rating handles repetitive 10/1000 μs pulses from motor back-EMF, avoiding thermal runaway due to RθJL = 66 °C/W and robust epoxy encapsulation. |
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 (SMB), 400 W rating, VWM = 408 V, VC = 658 V - identical electrical specs but surface-mount format. | Requires PCB redesign for SMT placement; not drop-in compatible with through-hole DO-41 footprint. | Select SMBJ480A only when migrating to automated assembly or space-constrained layouts. |
| 1.5KE480A | Higher peak pulse power (1500 W), same VWM/VBR, larger DO-201AD package, higher IPPM (2.2 A), VC = 658 V. | Over-specified for 400 W surge environments; adds cost and board area without functional benefit unless higher surge levels are expected. | Choose 1.5KE480A only if system-level testing confirms exposure to >400 W transients (e.g., direct lightning coupling). |
Compared with SMBJ480A and 1.5KE480A, P4KE480A-E3/54 offers optimal balance of proven DO-41 mechanical robustness, AEC-Q101 qualification, and precise 400 W surge handling-making it ideal for legacy through-hole designs requiring automotive-grade reliability without SMT conversion or over-engineering.

FAQ
What is the clamping voltage of P4KE480A-E3/54 under a 10/1000 μs surge?
The P4KE480A-E3/54 has a maximum clamping voltage (VC) of 658 V at its rated peak pulse current (IPPM) of 0.61 A under a 10/1000 μs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88365, and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is P4KE480A-E3/54 suitable for automotive applications?
Yes, P4KE480A-E3/54 is AEC-Q101 qualified (per note on page 3 and ordering information), making it suitable for automotive body electronics, power distribution modules, and infotainment power rails. Its –55 °C to +175 °C operating range and robust DO-41 construction meet stringent automotive environmental and reliability requirements.
What does the "E3/54" suffix mean in P4KE480A-E3/54?
The "E3" denotes RoHS-compliant, commercial-grade packaging meeting JESD201 Class 1A whisker test; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery with 5500 units per reel. This matches Vishay's ordering convention in the "Ordering Information" section (page 3).
How does P4KE480A-E3/54 differ from bidirectional variants like P4KE480CA?
P4KE480A-E3/54 is unidirectional with cathode marking and forward conduction capability (VF ≈ 5.0 V), whereas P4KE480CA is bidirectional-lacking polarity marking and symmetric clamping in both directions. The "A" suffix indicates unidirectional; "CA" indicates bidirectional, per Vishay's naming convention on page 1.
Can P4KE480A-E3/54 be used in AC line protection?
No-P4KE480A-E3/54 is unidirectional and not rated for continuous AC voltage reversal. For AC line protection, bidirectional types (e.g., P4KE480CA) or specialized AC-rated MOVs/TVS arrays are required. Its 408 V VWM applies only to DC or rectified DC applications.
