Product details
Overview
P6KE82CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 77.9–86.1 V breakdown voltage at 1 mA, 70.1 V stand-off voltage, 113 V maximum clamping voltage at 5.3 A, and AEC-Q101 qualification - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the P6KE82CAHE3/54 datasheet, P6KE82CAHE3/54 pinout, P6KE82CAHE3/54 application, or P6KE82CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C max junction temperature, low leakage (<1 μA at 70.1 V), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold (VBR = 77.9–86.1 V), it avalanches rapidly to limit voltage across protected circuitry. Its bidirectional symmetry ensures identical clamping behavior in both polarities - critical for AC-coupled or floating signal lines.
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling reliable operation up to 175 °C junction temperature. The glass-passivated junction delivers fast response time (<1 ns) and low incremental surge resistance, supporting repetitive 0.01% duty cycle surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 77.9–86.1 V at 1 mA test current - defines precise avalanche initiation threshold for overvoltage detection |
| Stand-off Voltage (VWM) | 70.1 V - maximum continuous working voltage before leakage exceeds 1 μA; sets safe operating margin below VBR |
| Clamping Voltage (VC) | 113 V at 5.3 A peak pulse current - actual voltage seen by protected circuit during worst-case 10/1000 μs surge |
| Peak Pulse Power (PPPM) | 600 W (10/1000 μs waveform) - quantifies single-event surge energy handling without failure |
| Junction Temperature Range | −55 °C to +175 °C - supports under-hood automotive and industrial environments without derating |
| Leakage Current (ID) | <1 μA at 70.1 V - ensures minimal loading on high-impedance signal paths during normal operation |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded package with 25.4 mm minimum lead length and UL 94 V-0 molded epoxy |

Use Value: UL 497B recognition validates system-level compliance; 113 V clamping ensures transceiver survival under 1 kV/μs slew rate transients per GR-1089-CORE. |
Use Scenario: Suppressing commutation spikes from brushed DC motors and solenoids in washing machines, HVAC actuators, and power tools. IC Role / Device Role / Timing Role: Across motor terminals or relay coil to absorb inductive kickback energy before it couples into MCU GPIO or power supply rails. Use Value: 175 °C junction rating allows placement near heat-generating motors; DO-15 form factor enables direct through-hole mounting on compact PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | DO-214AA package; 85 V nominal breakdown; 600 W rating; lower RθJA (50 °C/W) but no AEC-Q101 qualification | Suitable for space-constrained PCB layouts where surface-mount is preferred; lacks automotive qualification | Select SMBJ85CA only for commercial-grade consumer or industrial designs where AEC-Q101 is not mandated |
| 1.5KE82CA | Same DO-15 package; identical VBR range (77.9–86.1 V); higher 1500 W peak power but larger footprint and 10× higher leakage (10 μA) | Used where higher surge margin is required (e.g., outdoor telecom cabinets), but increases board area and standby power loss | Choose 1.5KE82CA only when 1500 W surge immunity is explicitly required and leakage tolerance permits ≥10 μA at VWM |
Compared with SMBJ85CA and 1.5KE82CA, P6KE82CAHE3/54 uniquely balances AEC-Q101 qualification, DO-15 through-hole compatibility, and 1 μA leakage - making it optimal for cost-sensitive automotive and industrial modules requiring proven reliability without SMT rework.

FAQ
What is the exact breakdown voltage range of the P6KE82CAHE3/54?
The P6KE82CAHE3/54 has a guaranteed breakdown voltage (VBR) range of 77.9 V to 86.1 V at 1 mA test current, measured per ANSI/IEEE C62.35. This range reflects manufacturing tolerance and ensures consistent clamping behavior across production lots - critical for designing predictable overvoltage protection margins in automotive and industrial systems using the P6KE82CAHE3/54.
Is the P6KE82CAHE3/54 suitable for automotive applications?
Yes, the P6KE82CAHE3/54 is AEC-Q101 qualified and carries the HE3 suffix indicating compliance with JESD 201 Class 2 whisker testing and full automotive reliability stress screening. Its −55 °C to +175 °C operating range, UL 497B recognition, and DO-15 mechanical robustness make it appropriate for engine control units, body electronics, and ADAS sensor interfaces where the P6KE82CAHE3/54 provides certified transient suppression.
How does the clamping voltage of P6KE82CAHE3/54 compare to its breakdown voltage?
The P6KE82CAHE3/54 clamps to a maximum of 113 V at 5.3 A peak pulse current (10/1000 μs), which is approximately 31–45% above its minimum breakdown voltage of 77.9 V. This clamping ratio (VC/VBR(min) ≈ 1.45) reflects low dynamic impedance during avalanche conduction - a key design advantage of the P6KE82CAHE3/54 for protecting voltage-sensitive ICs without excessive overshoot.
What does the 'CA' suffix mean in P6KE82CAHE3/54?
The 'CA' suffix in P6KE82CAHE3/54 denotes bidirectional configuration: the device provides symmetrical transient suppression for both positive and negative voltage excursions, with identical VBR, VC, and leakage characteristics in either polarity. Unlike unidirectional variants (e.g., P6KE82A), the P6KE82CAHE3/54 requires no polarity marking and is ideal for AC signal lines, differential buses, or floating grounds where polarity reversal may occur.
What is the maximum leakage current specification for P6KE82CAHE3/54 at its stand-off voltage?
The P6KE82CAHE3/54 specifies a maximum reverse leakage current (ID) of 1.0 μA at its stand-off voltage (VWM) of 70.1 V and 25 °C ambient temperature. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and battery-powered systems - a verified parameter confirmed in the Vishay datasheet Table "ELECTRICAL CHARACTERISTICS" for the P6KE82CAHE3/54.
