Product details
Overview
P6KE82CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. It features a 70.1V reverse standoff voltage (VRWM), 77.9V minimum breakdown voltage (VBR), 113V maximum clamping voltage (VC) at 5.3A peak pulse current, and DO-15 package with glass-passivated junction - used in industrial power supply input stages to absorb lightning-induced surges.
For engineers reviewing the P6KE82CA-T datasheet, P6KE82CA-T pinout, P6KE82CA-T application, or P6KE82CA-T equivalent, this page delivers verified electrical parameters, clamping behavior under 1.0ms 600W pulses, bidirectional surge response, thermal derating curves, and direct substitution guidance against active-replacement TVS diodes with matched VRWM and IPP ratings.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated die ensures stable VBR tolerance (±5%) and low leakage (<5µA @ VRWM), while the 1.0ms non-repetitive pulse rating aligns with IEC 61000-4-5 Level 4 surge immunity testing.
The device exhibits fast response time (<1.0ps), clamps transients within nanoseconds of onset, and maintains stable performance from –55°C to +175°C junction temperature. Its 20°C/W junction-to-case thermal resistance supports reliable operation under sustained surge duty cycles when mounted on ≥40mm² copper land.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (1.0ms 10/1000µs waveform; defines maximum transient energy absorption capability) |
| Reverse Standoff Voltage | 70.1V (maximum continuous DC or RMS voltage before significant leakage; sets operating margin) |
| Breakdown Voltage | 77.9V min / 86.1V max @ 1mA (tight VBR window ensures predictable turn-on threshold) |
| Clamping Voltage | 113V max @ 5.3A IPP (voltage seen by protected circuit during worst-case surge) |
| Peak Pulse Current | 5.3A (maximum single-event surge current it can divert without failure) |
| Junction Temperature Range | –55°C to +175°C (enables use in under-hood automotive or high-ambient industrial environments) |
| Package | DO-15 (industry-standard axial leaded package; compatible with through-hole PCB assembly and manual repair) |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body (UL 94V-0), 0.4g weight, 9.5mm lead length for thermal derating. Cathode band omitted on bidirectional version; marking reads "P6KE82CA" only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge current entry (negative polarity) | Conducts during negative transients; tied to protected line or ground reference |
| Cathode | Surge current entry (positive polarity) | Conducts during positive transients; tied to same node as anode for bidirectional symmetry |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals or ungrounded buses without polarity biasing |
| Glass-passivated junction | Ensures long-term VBR stability and low parameter drift across temperature and life cycle |
| 600W peak pulse rating | Meets IEC 61000-4-5 Level 4 (4kV/2Ω) surge test requirements for industrial equipment |
| RoHS-compliant lead finish | Lead-free plating meets MIL-STD-202 solderability standards and environmental compliance mandates |
Applications
| Industrial Power Input Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller exposed to load dump and ISO 7637-2 transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between input rail and ground, absorbing >95% of surge energy before downstream regulators. Use Value: Limits rail voltage to ≤113V during 5.3A surges, preventing damage to 36V-rated DC/DC converters and microcontrollers. | Use Scenario: LIN bus physical layer interface subjected to battery reversal and jump-start spikes. IC Role / Device Role / Timing Role: Bidirectional shunt protector across LIN signal pair (LIN-H/L), referenced to chassis ground. Use Value: Clamps ±113V transients within <1ns, preserving signal integrity and meeting ISO 17987-4 EMC immunity requirements. |
| AC-DC Adapter Secondary Side | Telecom Line Interface |
Use Scenario: Output rectifier stage of 48V telecom adapter where output must survive accidental short-to-input faults. IC Role / Device Role / Timing Role: Parallel-connected TVS across secondary winding output, triggered only during overvoltage events. Use Value: Activates at 77.9V, clamping fault voltage to 113V and limiting stress on 60V-rated output capacitors and optocouplers. | Use Scenario: Ethernet PHY interface with PoE injector, requiring protection against induced surges on data pairs. IC Role / Device Role / Timing Role: Bidirectional TVS per differential pair, mounted adjacent to RJ45 connector with minimal trace inductance. Use Value: Provides symmetrical clamping (±113V) with <5µA leakage at 70.1V, avoiding DC bias shift on 100Ω differential lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | Higher VRWM (72.2V), lower VC (116V @ 5.2A), SMB package (surface-mount) | Requires PCB re-layout; better suited for space-constrained designs with automated assembly | Select when board area is limited and thermal coupling to copper pour is optimized for SMB footprint |
| 1.5KE85CA | Same VRWM/VC specs but 1500W rating, larger DO-201 package, higher IPP (12.5A) | Over-specified for 600W needs; adds cost and board space without functional benefit | Choose only if future design requires headroom for higher-energy surges or legacy DO-201 compatibility |
Compared with SMBJ85CA and 1.5KE85CA, P6KE82CA-T offers optimal balance of proven reliability in through-hole industrial assemblies, precise 70.1V standoff matching common 24V/48V system margins, and cost-effective DO-15 manufacturability - making it ideal for field-serviceable or high-vibration deployments.

FAQ
Is P6KE82CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE82CA-T (document DS21502 Rev. 20–4 states "OBSOLETE – PART DISCONTINUED"). Aetrix Electronics maintains legacy inventory with full traceability and offers validated alternatives including SMBJ85CA and 1.5KE85CA for immediate drop-in or redesign support.
What is the difference between P6KE82A-T and P6KE82CA-T?
P6KE82A-T is unidirectional (cathode-banded), conducting only during positive surges; P6KE82CA-T is bidirectional (no cathode band), providing symmetrical clamping for both polarities. Their VRWM (70.1V), VBR (77.9V min), and VC (113V) are identical, but CA devices require no polarity-aware layout.
Can P6KE82CA-T be used in automotive applications?
While P6KE82CA-T meets basic AEC-Q101 stress-test conditions (e.g., temperature cycling, HTRB), it is not AEC-Q101 qualified out-of-box. Diodes offers AEC-Q101 variants (e.g., P6SMB82CA-Q) with PPAP documentation and IATF 16949 manufacturing - contact Aetrix for automotive-grade sourcing options.
How does thermal derating affect P6KE82CA-T's surge capability?
At ambient temperatures above +25°C, its 600W peak pulse power must be linearly derated per Fig. 4: at +75°C ambient, maximum usable pulse power drops to ~450W. Mounting on ≥40mm² copper land improves heat dissipation and extends usable surge capacity at elevated temperatures.
