Product details
Overview
P6KE6V8CA-B from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 6.8V reverse standoff voltage (VRWM), 10.5V max clamping voltage at 57A 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 P6KE6V8CA-B datasheet, P6KE6V8CA-B pinout, P6KE6V8CA-B application, or P6KE6V8CA-B equivalent, this page delivers verified electrical specs, clamping behavior under 1.0ms 8/20μs transients, thermal derating curves, and direct substitution guidance for legacy TVS replacement programs.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 6.45V (min) to 7.14V (max) under 10mA test current. Its fast response time (<1.0ns) and low clamping ratio (VC/VRWM ≈ 1.54) enable effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The device uses a glass-passivated junction for stable leakage performance (IR ≤ 1000μA at VRWM) and withstands 100A non-repetitive forward surge current (IFSM) per 8.3ms half-sine wave. Thermal resistance from junction to ambient is 75°C/W, requiring PCB copper land area design per JEDEC standards for steady-state dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W @ 1.0ms 10/1000μs waveform - defines maximum single-event surge energy handling capability |
| Reverse Standoff Voltage (VRWM) | 6.8V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 6.45–7.14V @ 10mA - voltage at which device enters avalanche conduction |
| Max Clamping Voltage (VC) | 10.5V @ 57A IPP - upper voltage limit seen by protected circuit during worst-case surge |
| Peak Pulse Current (IPP) | 57A @ 1.0ms - maximum transient current the device safely shunts without failure |
| Leakage Current (IR) | ≤1000μA @ VRWM - ensures minimal power loss and signal integrity in standby operation |
| Package | DO-15 - axial-leaded, through-hole plastic package rated UL 94V-0, 0.4g weight |
Pinout & Package
DO-15 package: axial-leaded, molded plastic housing with cathode band marking omitted on bidirectional variants (P6KE6V8CA-B). Leads are tin-plated, solderable per MIL-STD-202 Method 208; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (negative polarity) | Connects to line being protected; conducts during negative transients |
| Cathode | Transient current entry point (positive polarity) | Connects to line being protected; conducts during positive transients |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping symmetry | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| Glass-passivated die construction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| 600W peak pulse rating | Supports IEC 61000-4-5 Level 4 (4kV) surge immunity when properly mounted on ≥40mm² copper land |
| 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 Protection |
|---|---|
Use Scenario: Protecting 12V supply rail and LIN bus lines against load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of LDO regulators and CAN/LIN transceivers. Use Value: Limits rail voltage to ≤10.5V during 100V/50ms load dump events, preventing downstream IC latch-up or damage. |
Use Scenario: Shielding 24V digital input channels from field-wiring induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: Front-end transient absorber before optocoupler or Schmitt-trigger input stage. Use Value: Clamps 1kV/0.5J transients within 1ns, preserving input logic state integrity and reducing false triggering. |
| AC/DC Adapter Input Stage | RS-485 Transceiver Bus Line Protection |
Use Scenario: Safeguarding bridge rectifier output and bulk capacitor from AC line surges and switching noise. IC Role / Device Role / Timing Role: Secondary-side surge suppressor between rectifier and primary-side controller feedback path. Use Value: Absorbs 600W peak energy without degradation, maintaining regulation stability during EN 61000-4-4 EFT bursts. |
Use Scenario: Protecting differential A/B bus lines in multi-drop RS-485 networks exposed to ground potential differences. IC Role / Device Role / Timing Role: Common-mode TVS pair connected between A-GND and B-GND to suppress asymmetric surges. Use Value: Symmetrical 6.8V standoff enables ±10.5V clamping, preserving receiver common-mode range and data integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8CA | Same VRWM and VC, but SMC (DO-214AB) surface-mount package; 600W rating retained | Requires PCB redesign for SMT assembly; better thermal performance due to lower RθJA (50°C/W) | Select when migrating to automated assembly or improving thermal margin in space-constrained layouts |
| 1.5KE6.8CA | Higher 1500W peak power, same DO-15 package; VRWM = 6.8V, VC = 10.5V, IPP = 143A | Over-spec'd for most 600W use cases; larger junction capacitance may affect high-speed signal lines | Choose only where legacy 1.5KE footprint compatibility is required and higher surge margin is validated |
Compared with SMBJ6.8CA and 1.5KE6.8CA, P6KE6V8CA-B offers optimal cost-performance balance for through-hole prototyping and low-volume industrial builds, with verified DO-15 mechanical fit and established qualification history in automotive Tier-2 modules.

FAQ
Is P6KE6V8CA-B still in production?
No - Diodes Incorporated officially discontinued P6KE6V8CA-B as of August 2024 (DS21502 Rev. 20-4). Aetrix Electronics maintains limited legacy stock and supports transition to SMBJ6.8CA or 1.5KE6.8CA with full parametric validation and footprint adaptation guidance.
What is the difference between P6KE6V8A and P6KE6V8CA-B?
P6KE6V8A is unidirectional (cathode-banded); P6KE6V8CA-B is bidirectional (no cathode band, symmetrical clamping). Both share identical VRWM (6.8V), VBR (6.45–7.14V), and VC (10.5V), but only the 'C' suffix indicates bidirectional functionality per Diodes' ordering nomenclature.
Can P6KE6V8CA-B be used in place of P6KE6.8CA?
Yes - P6KE6V8CA-B and P6KE6.8CA are functionally identical; '6V8' is the metric notation for 6.8V (common in European datasheets), while '6.8' uses decimal notation. Both refer to the same 6.8V VRWM bidirectional TVS in DO-15 package.
What is the maximum operating temperature for P6KE6V8CA-B?
The junction and storage temperature range is –55°C to +175°C. At ambient temperatures above +25°C, peak pulse power must be derated linearly per Figure 4 in DS21502: at +75°C ambient, maximum PPK drops to ~450W; at +125°C, it falls to ~240W.
