Product details
Overview
P4KE8.2C from Taiwan Semiconductor is a bidirectional 400W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a nominal breakdown voltage of 8.2V, clamps transients to ≤12.5V at 33A peak pulse current, and operates across –55°C to +175°C junction temperature range - deployed in automotive lighting control modules and industrial sensor interfaces.
For engineers reviewing the P4KE8.2C datasheet, P4KE8.2C pinout, P4KE8.2C application, or P4KE8.2C equivalent, this page delivers verified electrical parameters, DO-41 package mechanical data, bidirectional clamping behavior, AEC-Q101 qualification status, and real-world ESD/inductive-spike protection use cases - all confirmed from Taiwan Semiconductor's official N2104 specification document.
Technical Context
The P4KE8.2C is a silicon avalanche diode configured as a bidirectional TVS, with symmetrical breakdown characteristics in both polarities. Its VBR min/max = 7.38V/9.02V at 10mA test current, VWM = 6.63V, and IR < 200μA at rated stand-off voltage - enabling reliable blocking during normal operation while triggering fast clamping under transients.
It sustains 400W peak pulse power per 10/1000μs waveform, achieves clamping voltage VC = 12.5V at IPPM = 33A, and exhibits <5.0ns response time from 0V to VBR. Thermal design is supported by TJ(MAX) = 175°C and UL 94V-0 mold compound compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.63 V - Maximum continuous reverse voltage before leakage exceeds 200 μA; defines safe operating margin below breakdown. |
| VBR @ 10 mA | 7.38–9.02 V - Measured breakdown voltage range at 10 mA; ensures predictable turn-on threshold for surge suppression. |
| VC @ 33 A | 12.5 V - Clamped voltage during 400W 10/1000μs surge; limits downstream IC stress to safe levels. |
| PPK | 400 W - Peak pulse power rating per standard 10/1000μs waveform; defines single-event energy handling capability. |
| TJ(MAX) | 175 °C - Maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments. |
| IPPM | 33 A - Peak pulse current corresponding to 400W clamping; used to size PCB trace width and layout clearance. |
| Response Time | <5.0 ns - Time from 0V to VBR in bidirectional mode; critical for suppressing EFT and contact ESD events. |
Pinout & Package
Package: DO-204AL (DO-41), axial-leaded, glass-passivated silicon junction. Cathode band marking omitted for bidirectional configuration (P4KE8.2C); polarity is non-directional per device function.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction terminals | No functional polarity - either lead connects to protected line or ground; enables universal placement on PCB without orientation check. |
Key Features
| Feature | Design Value |

Applications
| Automotive LED Headlamp Driver Protection | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protects LED driver ICs from load-dump spikes (>120V, 100ms) and alternator ripple during vehicle ignition cycles. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across input rail and chassis ground - absorbs energy before it reaches DC-DC controller. Use Value: Limits rail voltage to ≤12.5V during 33A transients, preventing latch-up or gate oxide damage in 40V-rated MOSFETs and op-amps. |
Use Scenario: Shields 24V digital input circuitry from inductive kickback generated by solenoid valves and relay coils in factory automation systems. IC Role / Device Role / Timing Role: Primary surge shunt located at connector entry point - clamps transients before they propagate through optocoupler input stage. Use Value: Maintains signal integrity by holding input voltage below 15V during 10/1000μs surges, avoiding false triggering or phototransistor saturation. |
| USB-C Port ESD Protection | Smart Meter Communication Interface Protection |
Use Scenario: Suppresses ±15kV contact ESD per IEC 61000-4-2 applied to USB-C CC and VBUS lines in portable diagnostic tools. IC Role / Device Role / Timing Role: Secondary-level TVS placed after common-mode choke - handles residual energy that bypasses front-end filtering. Use Value: Responds in <5ns to clamp ESD pulses to <15V, preserving USB PD controller functionality without system reset. |
Use Scenario: Guards RS-485 transceivers in utility smart meters against lightning-induced surges on long outdoor communication lines. IC Role / Device Role / Timing Role: Line-to-ground protector on differential bus pair - symmetric clamping prevents common-mode voltage shift beyond receiver tolerance. Use Value: Withstands 400W surges while maintaining <1% signal distortion at 10Mbps, ensuring uninterrupted DLMS/COSEM protocol transmission. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA (Bourns) | DO-214AA package; 600W rating; VBR = 8.89–9.83V; VC = 13.6V @ 44.1A | Higher power but larger footprint; requires re-layout due to SMD vs. axial DO-41 | Select when board space allows surface-mount integration and higher surge margin is required. |
| 1.5KE8.2C (ON Semiconductor) | Same DO-41 package; 1500W rating; VBR = 7.02–8.58V; VC = 13.4V @ 112A | Over-specified for 400W use cases; higher capacitance (150pF vs. ~50pF) may affect high-speed signal lines | Choose only if legacy design reuse or extreme surge margin (e.g., substation metering) justifies cost and layout impact. |
Compared with SMBJ8.0CA and 1.5KE8.2C, the P4KE8.2C offers optimal balance of compact DO-41 through-hole fit, AEC-Q101 qualification, and precise 8.2V clamping - making it preferred for cost-sensitive, space-constrained automotive and industrial control designs where 400W surge immunity suffices.

FAQ
What is the polarity configuration of P4KE8.2C?
The P4KE8.2C is a bidirectional TVS diode with symmetrical avalanche characteristics in both directions. Unlike unidirectional variants (e.g., P4KE8.2), it has no cathode band marking and functions identically regardless of lead orientation - ideal for AC-coupled or floating signal line protection where polarity is undefined.
Does P4KE8.2C meet AEC-Q101 requirements?
Yes, the P4KE8.2C is explicitly qualified to AEC-Q101 standards as documented in Taiwan Semiconductor's N2104 datasheet. This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge - confirming suitability for automotive powertrain and body electronics applications.
What is the maximum clamping voltage of P4KE8.2C under surge conditions?
The P4KE8.2C clamps to a maximum of 12.5V at 33A peak pulse current (10/1000μs waveform), as specified in the "Maximum clamping voltage VC@IPPM" parameter table. This value is guaranteed across the full operating temperature range and forms the basis for downstream IC voltage stress analysis.
Can P4KE8.2C be used in place of P4KE8.2 or P4KE8.2A?
No - P4KE8.2C is bidirectional, whereas P4KE8.2 and P4KE8.2A are unidirectional. Substituting P4KE8.2C for unidirectional types eliminates polarity sensitivity but increases leakage slightly above 10V; verify system-level reverse-bias behavior before replacement, especially in DC-biased circuits.
What is the thermal derating behavior of P4KE8.2C above 25°C ambient?
The P4KE8.2C follows standard JEDEC derating: its 400W peak pulse power is fully rated at TA = 25°C and linearly derates to zero at TJ = 175°C. For sustained operation, steady-state power dissipation is limited to 1W at TL = 75°C with 9.5mm lead length, per Figure 2 in the datasheet.
