Product details
Overview
P6KE82A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 82 V, clamps transients to ≤113 V at 5.5 A peak surge current, and maintains <1 μA reverse leakage at 70.1 V standoff voltage - enabling robust ESD and lightning surge protection in automotive body electronics and industrial control I/O modules.
For engineers reviewing the P6KE82A datasheet, P6KE82A pinout, P6KE82A application, or P6KE82A equivalent, this device is selected for high-energy transient suppression where fast response (<1 ps), low dynamic impedance, and AEC-Q101 qualification (in H-suffix variants) are critical - especially in 24 V/48 V vehicle subsystems, PLC analog input protection, and PoE-powered edge devices.
Technical Context
The P6KE82A operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its minimum breakdown threshold of 77.9 V. Its 10/1000 µs surge rating of 600 W defines energy-handling capability under standardized lightning impulse conditions, while its 0.105 %/°C temperature coefficient of VBR ensures predictable voltage drift across –55 °C to +175 °C junction temperatures.
Clamping performance is characterized by VC = 113 V at IPP = 5.5 A, delivering a clamping ratio (VC/VBR(min)) of ~1.45 - indicating tight voltage control during surge events. The DO-204AC (DO-15) package supports lead-free reflow soldering and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 77.9 V / 86.1 V at 1 mA test current - defines precise activation window for reliable overvoltage triggering without false trips |
| VWM | 70.1 V maximum working voltage - sets safe continuous operating limit below breakdown, allowing margin for ripple and tolerance |
| VC @ IPP | 113 V clamping voltage at 5.5 A peak pulse current - limits downstream voltage stress during 600 W transient events |
| IR @ VWM | <1 μA reverse leakage - minimizes standby power loss and avoids loading on sensitive reference or sensor circuits |
| PPK | 600 W non-repetitive peak pulse power (10/1000 µs) - certifies compliance with IEC 61000-4-5 Level 4 surge immunity testing |
| TJ(max) | +175 °C maximum junction temperature - enables operation in under-hood automotive or high-ambient industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with 0.400 g mass, tin-plated leads, and UL E326243 recognition |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, epoxy-molded, cathode indicated by band marking. Leads are pure tin-plated and solderable per J-STD-002. Mounting requires 5 × 5 mm copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / low-impedance return during clamping | Connected to system ground or lower-potential rail; carries full surge current during reverse-biased avalanche |
| Cathode | High-side connection point / voltage sensing node | Connected to protected line (e.g., 24 V supply); avalanche initiates here when VK–A exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| 600 W surge rating (10/1000 µs) | Validated energy absorption capacity for IEC 61000-4-5 surge immunity up to 4 kV line-to-ground in industrial equipment |
| Clamping voltage ≤113 V | Ensures protected ICs (e.g., CAN transceivers, ADC front-ends) remain below absolute maximum ratings during transients |
| Response time <1 ps | Enables suppression before fast-rising ESD or inductive spikes (e.g., relay coil flyback) propagate into circuitry |
| AEC-Q101 qualified option (P6KE82AH) | Supports automotive-grade reliability validation including temperature cycling, HTGB, and mechanical shock testing |
| RoHS & halogen-free (IEC 61249-2-21) | Meets global environmental compliance for consumer, industrial, and automotive end products without compromising thermal performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ85A | Same DO-214AC package; 85 V VBR min (80.8–89.2 V), 113 V VC @ 5.3 A, 400 W rating | Lower surge rating limits use in high-energy industrial surges; better suited for space-constrained PCBs | Select when board area is critical and 400 W surge margin suffices - not recommended for AEC-Q101 automotive designs |
| ON Semiconductor 1.5KE82A | Same DO-204AC package; identical VBR (77.9–86.1 V), VC = 113 V @ 5.5 A, but 1500 W rating (10/1000 µs) | Higher surge capacity allows single-device protection in harsher environments (e.g., railway signaling) | Choose when legacy 1.5KE footprint compatibility is required and higher energy handling justifies cost premium |
Compared with SMAJ85A and 1.5KE82A, the P6KE82A delivers optimal balance of 600 W surge capability, AEC-Q101 availability (as P6KE82AH), and cost-effective DO-15 packaging - making it ideal for volume automotive and industrial applications where reliability and standardization are prioritized over extreme energy margins.

FAQ
What is the maximum clamping voltage of the P6KE82A under surge conditions?
The P6KE82A clamps to a maximum of 113 V when subjected to its rated 5.5 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures protected downstream components remain within their absolute maximum voltage ratings during transient events. The P6KE82A achieves this with low dynamic impedance and sub-nanosecond response.
Is the P6KE82A suitable for automotive applications?
Yes - the P6KE82A is available in an AEC-Q101 qualified variant (P6KE82AH) that undergoes rigorous stress testing including temperature cycling, high-temperature gate bias, and mechanical shock. While the base P6KE82A is not AEC-Q101 certified, its 175 °C TJ(max), low leakage, and robust surge rating make it widely used in non-safety-critical automotive subsystems such as lighting control and infotainment power rails.
How does the P6KE82A differ from the P6KE82 (non-A suffix)?
The P6KE82A has tighter breakdown voltage tolerances (77.9–86.1 V) versus the P6KE82 (73.8–90.2 V), resulting in more consistent clamping behavior and reduced risk of premature conduction. Both share the same DO-204AC package, 600 W rating, and thermal specifications, but the 'A' suffix denotes enhanced parameter uniformity critical for high-volume industrial and automotive designs where binning consistency matters.
Can the P6KE82A be used in bidirectional configurations?
No - the P6KE82A is a unidirectional TVS diode intended for DC line protection with defined anode/cathode polarity. For bidirectional AC or data-line protection, Taiwan Semiconductor offers the P6KE82CA variant (with 'CA' suffix), which provides symmetrical clamping in both directions and uses the same DO-204AC package but different internal die construction and marking.
What is the recommended PCB layout practice for the P6KE82A?
For optimal surge performance, route the P6KE82A with minimal trace length between cathode and protected line, and connect the anode directly to a low-inductance ground plane. Use 5 × 5 mm copper pads per lead as specified in the datasheet to sustain 5 W steady-state dissipation at 75 °C ambient. Avoid thermal reliefs on mounting pads to ensure efficient heat transfer during repetitive surge events.
