Product details
Overview
P6KE82CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 82 V, clamps transients to ≤118 V at 5.3 A peak surge current, and delivers fast response (<1.0 ps from 0 V to VBR), low dynamic impedance, and AEC-Q101 qualification for automotive under-hood applications.
For engineers reviewing the P6KE82CH datasheet, P6KE82CH pinout, P6KE82CH application, or P6KE82CH equivalent, key selection criteria include its DO-204AC (DO-15) package compatibility, 66.4 V stand-off voltage, <1 μA leakage above 10 V, and suitability for ESD/inductive-switching transient suppression in automotive ECUs, industrial power supplies, and lighting drivers.
Technical Context
The P6KE82CH operates as a silicon avalanche diode with unidirectional polarity, leveraging controlled reverse-biased avalanche breakdown to clamp transient voltages. Its junction temperature range spans −55 °C to +175 °C, and it sustains non-repetitive 10/1000 μs surges up to 600 W without degradation.
It exhibits a temperature coefficient of VBR of 0.105 %/°C and maintains stable clamping performance across ambient temperatures due to derating curves defined per Fig.2. The device uses pure tin-plated leads compliant with J-STD-002 and meets UL 94V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - Sustains high-energy transients common in automotive load-dump or inductive switching events |
| Stand-Off Voltage (VWM) | 66.4 V - Maximum continuous DC operating voltage before leakage exceeds 1 μA |
| Breakdown Voltage (VBR, min/max) | 73.8 V / 90.2 V at 1 mA - Ensures reliable triggering within specified tolerance band under production conditions |
| Clamping Voltage (VC @ IPP) | 118 V at 5.3 A - Limits downstream circuit stress during worst-case surge, enabling robust system-level immunity |
| Junction Temperature Range | −55 °C to +175 °C - Supports operation in harsh environments including engine compartments and industrial enclosures |
| Leakage Current (ID @ VWM) | ≤1 μA - Minimizes standby power loss and avoids false triggering in low-power sensing circuits |
| Response Time | <1.0 ps - Enables effective suppression of nanosecond-scale ESD and fast-transient events |

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 SMAJ82A | Same DO-214AC (SMA) package; lower 400 W rating; VC = 135 V @ 4.4 A | Less suitable for high-energy load-dump; better for space-constrained PCBs | Select if board layout requires surface-mount and surge energy is ≤400 W |
| Vishay 1.5KE82A | Higher 1500 W rating; larger DO-201AD package; VC = 137 V @ 11 A | Overqualified for 600 W needs but offers higher margin in extreme environments | Select if future design scalability or MIL-STD-1275B compliance is required |
Compared with P6KE82CH, SMAJ82A trades surge capacity for smaller footprint, while 1.5KE82A provides greater energy headroom at the cost of board area and thermal mass-making P6KE82CH optimal for cost-sensitive, AEC-Q101–mandated 600 W protection in axial-leaded designs.

FAQ
What is the maximum clamping voltage of the P6KE82CH under rated surge conditions?
The P6KE82CH clamps to a maximum of 118 V when subjected to a 5.3 A peak pulse current with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees predictable overvoltage limiting for downstream ICs. The clamping performance remains stable across its full operating temperature range, making P6KE82CH suitable for critical protection in automotive and industrial systems.
Is the P6KE82CH AEC-Q101 qualified, and what does that mean for automotive use?
Yes, the P6KE82CH carries the "H" suffix indicating full AEC-Q101 qualification-verified through stress tests including temperature cycling, mechanical shock, and high-temperature reverse bias. This certification confirms its reliability in automotive under-hood environments where P6KE82CH protects sensitive ECUs and body-control modules against real-world transients like load dump and alternator ripple.
How does the P6KE82CH differ from the P6KE82A variant?
The P6KE82CH is AEC-Q101 qualified and optimized for automotive applications, whereas P6KE82A lacks the "H" suffix and is intended for commercial/industrial use only. Both share identical electrical specs-including 73.8–90.2 V VBR, 66.4 V VWM, and 118 V VC-but P6KE82CH undergoes additional qualification testing and traceability controls required for Tier-1 automotive supply chains.
What package type and mounting method does the P6KE82CH use?
The P6KE82CH uses the DO-204AC (DO-15) axial-leaded package with cathode band marking, designed for through-hole mounting on PCBs. Its pure tin-plated leads comply with J-STD-002 solderability standards, and the epoxy case meets UL 94V-0 flammability requirements-ensuring mechanical robustness and process compatibility in high-volume assembly of P6KE82CH into automotive and industrial boards.
Can the P6KE82CH be used in bidirectional configurations?
No-the P6KE82CH is a unidirectional TVS diode, indicated by the "CH" suffix and cathode band marking. For bidirectional protection, Taiwan Semiconductor offers the P6KE82C variant (not P6KE82CH). Using P6KE82CH in reverse-biased configurations risks permanent damage, as it is not rated for symmetrical conduction; always verify polarity alignment during P6KE82CH placement in schematics and layouts.
