Product details
Overview
P6KE8V2CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power rails and signal lines. It features a 7.02V minimum breakdown voltage, 8.61V maximum standoff voltage, 12.1V clamping voltage at 50A peak pulse current, and DO-15 glass-passivated package-used in automotive body control modules, industrial PLC I/O protection, and AC/DC adapter input stages.
For engineers reviewing the P6KE8V2CA-T datasheet, P6KE8V2CA-T pinout, P6KE8V2CA-T application, or P6KE8V2CA-T equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal derating curves, DO-15 mechanical data, and direct substitution guidance against active-production TVS alternatives with matching VRWM and IPP ratings.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping during positive and negative transients without polarity-dependent biasing. Its glass-passivated junction ensures stable leakage (<200 µA @ 7.02V) and fast response (<1.0 ns), critical for protecting sensitive analog inputs and microcontroller GPIOs.
The device sustains 600W peak pulse power (10/1000 µs waveform), supports 100A non-repetitive forward surge current, and exhibits 20°C/W junction-to-case thermal resistance-enabling reliable operation under repeated lightning-induced surges when mounted on ≥40 mm² copper land.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - Sustains single 10/1000 µs surge events common in IEC 61000-4-5 Level 4 testing. |
| Reverse Standoff Voltage | 7.02–8.61 V - Defines maximum continuous DC operating voltage before significant leakage begins. |
| Clamping Voltage | 12.1 V @ 50 A - Limits transient voltage seen by downstream circuitry during worst-case surge conditions. |
| Breakdown Voltage | 7.79 V min @ 10 mA - Confirmed avalanche onset point; ensures predictable turn-on margin above VRWM. |
| Leakage Current | ≤200 µA @ 7.02 V - Low standby loss suitable for battery-backed or low-power sensor nodes. |
| Package | DO-15 - Standard axial-leaded through-hole package with 0.4 g mass and UL 94V-0 flammability rating. |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body, cathode band not marked (bidirectional), lead length 9.5 mm, weight ≈0.4 g, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional transient conduction path | No polarity marking required; identical clamping performance for +ve and –ve transients. |
| Lead 1 | Current entry/exit terminal | Plated for solderability per MIL-STD-202; thermal path to PCB copper for power dissipation. |
| Lead 2 | Current entry/exit terminal | Electrically identical to Lead 1; enables mounting in either orientation on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Enables compliance with IEC 61000-4-5 surge immunity up to 4 kV (line-earth) in Class B equipment. |
| Glass-passivated die construction | Ensures long-term stability of breakdown voltage and leakage under temperature cycling and humidity stress. |
| Bidirectional clamping symmetry | Eliminates need for polarity-aware layout; simplifies ESD/surge protection on AC-coupled or floating signals. |
| RoHS-compliant lead finish | Meets EU Directive 2011/65/EU with full exemption documentation; compatible with lead-free reflow profiles. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|
Use Scenario: Protects 12V supply rail and LIN bus pins from load dump and inductive switching spikes. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed directly at connector entry point before LDO regulator. Use Value: Clamps 12V rail transients to ≤12.1V, preventing damage to 5V logic-level MCU peripherals rated for 16V absolute max. |
Use Scenario: Shields 24V digital input optocoupler front-end from field-wiring induced surges. IC Role / Device Role / Timing Role: Fast-acting shunt element that diverts >50A surge energy away from series current-limiting resistor and LED anode. Use Value: Maintains <200 µA leakage at 24V nominal, ensuring clean high-state detection without false triggering. |
| AC/DC Adapter Input Stage | USB-C Power Delivery Interface |
Use Scenario: Suppresses differential-mode surges on primary-side rectifier output before bulk capacitor. IC Role / Device Role / Timing Role: Secondary-level surge protector placed after MOV but before primary controller IC. Use Value: Adds precise 12.1V clamping threshold where MOV tolerance (±20%) is insufficient for tight-margin controllers. |
Use Scenario: Guards CC1/CC2 pins against ESD and hot-plug transients during USB-C cable insertion. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF) bidirectional clamp integrated into ESD protection array near connector. Use Value: Delivers sub-1ns response with no polarity dependency-critical for bidirectional CC line signaling integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA-T | 400W peak power, SMB package (surface-mount), 8.0V VRWM, 12.2V VC @ 32.8A | Lower surge rating; suited for space-constrained PCBs where 600W is not required | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 3. |
| 1.5KE8.2CA-T | 1500W peak power, DO-201 package, 8.2V VRWM, 13.4V VC @ 112A | Higher power handling but larger footprint and higher clamping voltage | Choose for legacy designs requiring higher surge margin or compatibility with existing DO-201 footprints. |
Compared with P6KE8V2CA-T, SMBJ8.0CA-T offers smaller size but reduced surge robustness, while 1.5KE8.2CA-T provides greater energy absorption at the cost of higher clamping and board space-making P6KE8V2CA-T optimal for cost-sensitive, through-hole 600W protection where DO-15 is already standardized.

FAQ
Is P6KE8V2CA-T still in active production?
No-P6KE8V2CA-T is officially obsolete per Diodes' DS21502 Rev. 20-4 (August 2024). Aetrix Electronics maintains limited legacy stock for continuity support, but no new production runs are scheduled. Customers should evaluate SMBJ8.0CA-T or 1.5KE8.2CA-T for new designs requiring functional equivalence.
What is the difference between P6KE8V2A-T and P6KE8V2CA-T?
P6KE8V2A-T is unidirectional (cathode-banded), clamping only negative transients relative to its marked cathode; P6KE8V2CA-T is bidirectional (no band), providing symmetrical clamping for both polarities. Their VRWM, VBR, and VC values are identical, but circuit placement and polarity awareness differ.
Can P6KE8V2CA-T be used in surface-mount designs?
No-it is strictly a DO-15 axial-leaded through-hole device. Attempting SMT reflow will damage the molded plastic body and compromise hermeticity. For surface-mount equivalents, consider SMBJ8.0CA-T (SMB package) or SMCJ8.0CA-T (SMC package), both offering comparable VRWM and clamping performance.
What is the maximum ambient temperature for continuous operation?
The P6KE8V2CA-T supports ambient temperatures from –55°C to +175°C, but steady-state power dissipation drops linearly above +25°C. At +75°C ambient, its rated PD is 5.0 W when mounted on 40 mm² copper; derating follows Fig. 4 in DS21502, reaching zero at ~200°C ambient.
