Product details
Overview
P6KE82-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 70.1 V standoff voltage (VWM), 77.9–86.1 V breakdown range (VBR at 1 mA), 113 V maximum clamping voltage at 5.3 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and DO-204AC (DO-15) package - deployed in automotive power supply inputs and industrial sensor interface circuits.
For engineers reviewing the P6KE82-E3/73 datasheet, P6KE82-E3/73 pinout, P6KE82-E3/73 application, or P6KE82-E3/73 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, RoHS-compliant packaging details, and AEC-Q101 qualification status - all critical for ESD/surge protection design validation and BOM selection.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below VWM = 70.1 V, then avalanches sharply at VBR = 77.9–86.1 V to divert transient energy. Its 113 V clamping voltage at 5.3 A (10/1000 µs) ensures downstream ICs see limited overvoltage during 600 W surges.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient); power dissipation derates linearly above 25 °C ambient, reaching zero at 175 °C junction temperature - consistent with its -55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 70.1 V - Maximum continuous DC or RMS voltage the device blocks without conduction; sets minimum system operating margin before clamping. |
| VBR (Breakdown Voltage) | 77.9–86.1 V at 1 mA - Confirmed avalanche onset range; defines threshold where clamping begins under controlled test conditions. |
| VC (Clamping Voltage) | 113 V at IPPM = 5.3 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; determines maximum stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy-handling capability per single 10/1000 µs waveform; enables robust protection against lightning-induced or inductive-switching transients. |
| IFSM (Surge Current) | 100 A (8.3 ms half-sine) - Non-repetitive forward surge rating; validates survivability during high-energy fault events like load dump. |
| TJmax | 175 °C - Maximum junction temperature; supports operation in under-hood automotive and high-temperature industrial environments. |
| Package | DO-204AC (DO-15) - Standard axial-leaded through-hole package with UL 94 V-0 molded epoxy; compatible with legacy PCB layouts and wave soldering (275 °C, 10 s). |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, glass-passivated silicon junction, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage rail; completes shunt path during avalanche conduction. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 24 V supply); carries full surge current into anode during clamping event. |
Key Features
| Feature | Design Value |
|---|---|

| 600 W peak pulse power (10/1000 µs) | Supports protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) in 24 V systems with appropriate series impedance. |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including engine control units, body electronics, and infotainment power supplies. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), improving protection fidelity for sensitive analog front-ends. |
| RoHS-compliant, commercial-grade (E3) | Meets EU RoHS Directive 2011/65/EU; suitable for industrial, consumer, and telecom equipment requiring lead-free assembly. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|

IC Role / Device Role: Bidirectional protection (using CA variant) or unidirectional rail clamp on signal conditioning amplifier inputs. Use Value: Limits induced voltage spikes to safe levels (<113 V) without loading the 250 Ω loop impedance during normal operation. |
| Telecom DC Power Feeds | Consumer Device USB/DC Jack Protection |
|
Use Scenario: -48 V telecom rectifier outputs feeding base station radios vulnerable to lightning-induced surges on outdoor cabling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | DO-214AA package; lower VWM = 6.8 V; same 600 W rating but higher IPPM = 64.6 A at VC = 13.6 V. | Suitable for 5 V rail protection; not interchangeable due to different VWM/VC and surface-mount form factor. | Select when board space is constrained and 5 V system clamping is required; requires re-layout. |
| 1.5KE82A | Same DO-204AC package and VWM/VBR specs; higher PPPM = 1500 W; larger package volume and higher cost. | Used where higher surge margin is mandated (e.g., industrial motor drives); identical pinout but heavier thermal mass. | Choose for enhanced surge endurance in harsh environments; no PCB change needed but verify mechanical clearance. |
Compared with SMBJ8.0A and 1.5KE82A, P6KE82-E3/73 offers optimal balance of 600 W surge capability, DO-204AC through-hole compatibility, and cost-effective AEC-Q101 qualification - making it ideal for mid-tier automotive and industrial power rail protection where layout reuse and qualification traceability are prioritized.

FAQ
What is the maximum clamping voltage of the P6KE82-E3/73 under standard surge conditions?
The P6KE82-E3/73 has a maximum clamping voltage (VC) of 113 V when subjected to a 10/1000 µs waveform with a peak pulse current (IPPM) of 5.3 A. This value is measured per JEDEC standards and reflects the highest voltage the protected circuit will experience during that defined transient event. The P6KE82-E3/73 maintains this clamping performance consistently across its rated temperature range and lifetime, provided layout and thermal conditions meet Vishay's recommendations.
Is the P6KE82-E3/73 suitable for automotive applications?
Yes, the P6KE82-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body control modules, and infotainment power supplies. Its -55 °C to +175 °C operating junction temperature range, 100 A 8.3 ms surge rating, and DO-204AC mechanical robustness meet automotive environmental and reliability requirements. The P6KE82-E3/73 E3 suffix confirms RoHS compliance and whisker testing per JESD 201 Class 1A.
How does the P6KE82-E3/73 differ from bi-directional TVS variants like P6KE82CA?
The P6KE82-E3/73 is unidirectional and features a cathode band for polarity identification, enabling DC rail protection with reverse-bias blocking. In contrast, P6KE82CA is bi-directional, lacks polarity marking, and clamps transients of either polarity - suited for AC lines or differential signal pairs. Their VBR, VC, and PPPM ratings differ slightly due to internal structure; the P6KE82-E3/73 cannot substitute for P6KE82CA in AC-coupled applications without circuit redesign.
What is the thermal resistance profile of the P6KE82-E3/73?
The P6KE82-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W at 25 °C ambient. Its power dissipation derates linearly above 25 °C, reaching zero at 175 °C junction temperature - documented in Figure 5 of the Vishay datasheet. Proper lead length (≥9.5 mm) and copper pour area are essential to achieve the specified RθJL in production layouts.
Can the P6KE82-E3/73 be used in place of the older P6KE82A without design changes?
Yes, the P6KE82-E3/73 is a direct replacement for P6KE82A, sharing identical electrical specifications, DO-204AC package dimensions, pinout, and thermal characteristics. The "E3/73" suffix denotes RoHS-compliant, commercial-grade packaging with matte tin plating and JESD 201 Class 1A whisker resistance - fully backward-compatible with legacy P6KE82A designs requiring no PCB or schematic modifications.
