Product details
Overview
P6KE82AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary 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 delivers sub-nanosecond response (<1.0 ps) to ESD and lightning-induced surges - deployed in automotive body control modules and industrial PLC I/O protection.
For engineers reviewing the P6KE82AH datasheet, P6KE82AH pinout, P6KE82AH application, or P6KE82AH equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package compatibility with high-density PCB layouts, 70.1 V minimum standoff voltage, and 1 μA leakage at 70.1 V - critical for low-power sensor interfaces and battery-backed systems requiring minimal quiescent current.
Technical Context
The P6KE82AH operates as a silicon avalanche diode with unidirectional polarity, leveraging controlled reverse-biased breakdown to clamp transient energy before downstream ICs are damaged. Its 10/1000 μs surge rating of 600 W and maximum clamping voltage of 113 V at 5.5 A define its robustness against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3 threats.
Thermal design relies on junction-to-ambient conduction through DO-15 leads mounted on 5 × 5 mm copper pads; derating begins above 25°C ambient per Fig.2, with absolute max junction temperature of +175°C and storage range from −55°C to +175°C. The device exhibits a VBR temperature coefficient of 0.105 %/°C, enabling predictable voltage drift across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000μs) | 600 W - sustains single high-energy transients without failure, meeting IEC 61000-4-5 line surge requirements |
| Breakdown Voltage VBR (min/max) | 77.9 V / 86.1 V at 1 mA - ensures reliable triggering above normal operating rail (e.g., 72 V battery systems) |
| Standoff Voltage VWM | 70.1 V - defines maximum continuous DC voltage the device blocks without leakage exceeding 1 μA |
| Clamping Voltage VC @ IPP | 113 V at 5.5 A - limits voltage seen by protected ICs during worst-case surge, preserving 20+ V margin for 90 V-rated components |
| Junction Temperature Range | −55°C to +175°C - supports under-hood automotive placement and industrial high-temp environments |
| Leakage Current ID @ VWM | ≤1 μA - enables use in always-on circuits (e.g., CAN bus nodes) without measurable standby power penalty |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with UL 94V-0 flammability rating and pure tin-plated leads compliant with J-STD-002 solderability. Cathode identified by band marking; polarity must be observed in series connection with protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; completes clamping loop during transient event |
| Cathode | Protected line input | Connected to supply rail or signal line being safeguarded; avalanche conduction occurs cathode-to-anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS power domains |
| Low dynamic impedance | Enables rapid voltage stabilization during fast-rising transients (e.g., ESD >15 kV contact discharge) |
| Sub-1 ps response time | Triggers before most microsecond-scale transients fully develop, preventing latch-up in CMOS ICs |
| 600 W surge capability | Handles repetitive 10/1000 μs surges up to 4 pulses/minute without degradation per JEDEC standards |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing compliance |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85A | 600 W rating, DO-214AA package, 85 V nominal, 130 V clamping at 4.6 A | Surface-mount alternative with higher thermal resistance; requires larger pad area for equivalent power dissipation | Select when board space constraints favor SMD or automated assembly is required |
| 1.5KE82A | Same DO-15 package, 600 W rating, but non-AEC-Q101; 82 V nominal, 118 V clamping at 5.3 A | Lacks automotive qualification; suitable for industrial/commercial only where AEC compliance is not mandated | Select for cost-sensitive non-automotive designs where AEC-Q101 is unnecessary |
Compared with SMBJ85A and 1.5KE82A, the P6KE82AH uniquely combines AEC-Q101 qualification, axial DO-15 form factor, and 113 V clamping performance - making it the preferred choice for automotive front-end protection where reliability, legacy through-hole compatibility, and strict voltage limiting are jointly required.

FAQ
What is the maximum clamping voltage of the P6KE82AH under rated surge conditions?
The P6KE82AH has a maximum clamping voltage (VC) of 113 V when subjected to its rated peak pulse current of 5.5 A using the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected circuitry will not experience voltages exceeding 113 V during standardized surge events, ensuring compatibility with 125 V-rated downstream components.
Is the P6KE82AH suitable for bidirectional transient protection?
No, the P6KE82AH is a unidirectional TVS diode and is not rated for bidirectional operation. Its electrical specifications - including breakdown voltage, clamping behavior, and polarity marking - apply only in the reverse-biased direction. For bidirectional protection, select the P6KE82CA variant, which provides symmetrical clamping in both polarities.
Does the P6KE82AH meet AEC-Q101 stress test requirements?
Yes, the P6KE82AH is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H". It has passed all required stress tests including high-temperature reverse bias (HTRB), temperature cycling, mechanical shock, and ESD (HBM ≥8 kV), confirming suitability for automotive powertrain and chassis applications.
What is the standoff voltage (VWM) specification for the P6KE82AH?
The P6KE82AH has a maximum standoff voltage (VWM) of 70.1 V, meaning it reliably blocks voltages up to this level in normal operation while maintaining reverse leakage current ≤1 μA. This allows safe use on 60 V nominal systems (e.g., 48 V automotive architectures with 20% tolerance) without false triggering.
Can the P6KE82AH be used in parallel for higher surge current handling?
No - paralleling P6KE82AH devices is not recommended due to parameter mismatch (e.g., VBR tolerance ±5%) causing uneven current sharing and potential thermal runaway. For higher surge ratings, select a single higher-power device such as the 1500W P15KE82AH or consult TSC's application notes on staged protection topologies.
