Product details
Overview
P6KE6V8CA from STMicroelectronics is a bidirectional transient voltage suppression (TVS) diode in DO-15 package, designed for ESD and surge protection in low-voltage DC power rails and signal lines. It features a 5.8 V stand-off voltage (VRM), 6.8 V breakdown voltage (VBR) at 1 mA, 10.5 V clamping voltage (VCL) at 57 A peak pulse current (IPP), and 600 W peak pulse power rating (10/1000 µs), making it suitable for protecting USB ports, industrial sensor interfaces, and automotive body electronics.
For engineers reviewing the P6KE6V8CA datasheet, P6KE6V8CA pinout, P6KE6V8CA application, or P6KE6V8CA equivalent, key selection criteria include bidirectional clamping behavior, low leakage (<10 µA at VRM), high junction temperature capability (Tj up to +175 °C), and IEC 61000-4-2/4-4 compliance - critical for robustness in harsh electromagnetic environments.
Technical Context
The P6KE6V8CA uses planar junction silicon technology to achieve low dynamic resistance (RD = 0.059 Ω) and stable clamping performance across temperature. Its bidirectional configuration enables symmetric surge suppression on AC-coupled or floating lines without polarity concerns.
It delivers 30 kV ESD immunity (air/contact discharge per IEC 61000-4-2) and withstands 4 kV fast transient bursts (IEC 61000-4-4 Level 4), with thermal derating down to 300 W at Tj = 175 °C - enabling reliable operation in thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRM) | 5.8 V - Maximum continuous reverse operating voltage before significant leakage begins. |
| Breakdown Voltage (VBR) | 6.45–7.14 V @ 1 mA - Tight tolerance ensures predictable turn-on during transients. |
| Clamping Voltage (VCL) | 10.5 V @ 57 A (10/1000 µs) - Limits voltage seen by protected ICs to safe levels. |
| Peak Pulse Power (PPP) | 600 W (10/1000 µs), 4 kW (8/20 µs) - Supports high-energy surge events in compact form factor. |
| Leakage Current (IRM) | ≤10 µA @ VRM - Minimizes standby power loss in battery-powered systems. |
| Junction Temperature Range | −55 °C to +175 °C - Enables deployment in under-hood automotive or industrial control cabinets. |
| ESD Rating | ±30 kV (contact/air discharge, IEC 61000-4-2) - Exceeds Level 4 requirements for end-equipment certification. |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with cathode band marking. Bidirectional symmetry means both terminals function identically - no anode/cathode orientation required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Surge current path (bidirectional) | Either terminal accepts positive or negative transients - simplifies layout and eliminates polarity errors. |
| Case (body) | Thermal conduction path | DO-15 metal-glass junction provides direct heat transfer to PCB copper pour for sustained surge handling. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals or ungrounded buses without external polarity management. |
| Low dynamic resistance (RD) | 0.059 Ω ensures minimal voltage overshoot during fast-rising surges (e.g., EFT pulses). |
| High-temperature operation | Rated for continuous use up to +175 °C junction temperature - supports placement near power components. |
| UL 497B certified | QVGQ2.E136224 listing confirms suitability for telecom/data line protection per safety standards. |
| Matte tin lead finish | RoHS-compliant plating compatible with Pb-free reflow (J-STD-020 MSL Level 1) and wire bonding. |
Applications
| USB 2.0 Data Lines | Automotive Body Control Module Inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.8CA (ON Semiconductor) | Same DO-214AC package; slightly higher VBR (6.47–7.15 V) and VCL (11.5 V @ 53.5 A); lower PPP (400 W). | Limited to lower-energy surges; less margin for repeated 600 W events. | Preferred where board space constraints favor SMD over axial DO-15. |
| 1.5KE6.8CA (Littelfuse) | Higher PPP (1500 W), larger DO-201AD package; VBR (6.12–6.8 V), VCL (10.5 V @ 143 A). | Overkill for low-energy ESD-only use; requires more PCB area and thermal relief. | Chosen when legacy designs mandate 1.5 kW surge headroom or existing footprint compatibility. |
Compared with SMAJ6.8CA and 1.5KE6.8CA, the P6KE6V8CA offers optimal balance of axial-mount reliability, 600 W surge capacity, and tight 5.8–7.14 V voltage window - ideal for cost-sensitive, space-constrained industrial and automotive subsystems where DO-15 mechanical robustness is valued.

FAQ
What is the difference between P6KE6V8A and P6KE6V8CA?
The "A" suffix denotes unidirectional TVS diodes with defined anode/cathode polarity, while "CA" indicates bidirectional devices with symmetrical clamping characteristics. P6KE6V8CA protects both positive and negative transients on the same line without regard to DC bias direction - essential for AC-coupled or floating signal paths like RS-485 or audio lines.
Can P6KE6V8CA be used in place of a Zener diode for voltage regulation?
No - P6KE6V8CA is not designed for continuous voltage regulation. It operates only during transient overvoltage events and exhibits high leakage above VRM. Its VBR has ±5% tolerance and lacks the stable dynamic impedance needed for precision regulation; dedicated Zener diodes (e.g., BZX84-C6V8) must be used for steady-state biasing.
Does P6KE6V8CA require heatsinking for 600 W pulse handling?
No external heatsink is required for single 10/1000 µs pulses, as thermal mass of the DO-15 package and PCB copper pour suffices. However, for repetitive surges (>1 Hz), thermal design must follow Figure 11 and 12 in DS0681 - minimum 1 cm² copper area per lead and FR4 board thickness ≥1.6 mm are recommended to maintain Tj ≤175 °C.
Is P6KE6V8CA compliant with AEC-Q200 for automotive use?
P6KE6V8CA is not AEC-Q200 qualified. While it meets automotive-relevant specs (Tj = −55 to +175 °C, IEC 61000-4-2/4-4), ST does not list it in their AEC-Q200 stress-tested product catalog. For qualified alternatives, consider ST's Automotive TVS series such as SMAJ6.8CA-Q or 1.5SMC6.8CA-Q, which undergo full temperature cycling, humidity, and vibration testing.
