Product details
Overview
P6KE6V8A-T from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 5.80V reverse standoff voltage (VRWM), 6.45V minimum breakdown voltage (VBR), 10.5V maximum clamping voltage (VC) at 57A peak pulse current, and DO-15 package with glass-passivated junction - used in automotive body control modules and industrial PLC I/O protection.
For engineers reviewing the P6KE6V8A-T datasheet, P6KE6V8A-T pinout, P6KE6V8A-T application, or P6KE6V8A-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, 10.5V VC at 57A IPP under 1.0ms 8/20μs waveform, unidirectional polarity marking, and DO-15 lead-form compatibility with legacy through-hole PCB layouts.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold (6.45–7.14V), it avalanches into low-impedance conduction within <1ns, diverting surge current away from downstream circuitry. Its glass-passivated die ensures stable leakage performance and long-term reliability under thermal cycling.
The device sustains 600W non-repetitive peak pulse power (tP = 1.0ms), supports 100A forward surge current (8.3ms half-sine), and exhibits 1000μA max reverse leakage at VRWM - critical for low-power standby circuits where quiescent current must remain below 1μA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W at 1.0ms pulse - defines maximum transient energy absorption without failure |
| Reverse Standoff Voltage | 5.80V - maximum continuous DC voltage before significant leakage begins |
| Breakdown Voltage | 6.45V min @ 10mA - precise avalanche initiation point for predictable clamping onset |
| Clamping Voltage | 10.5V max @ 57A - limits voltage seen by protected IC during worst-case surge |
| Package | DO-15 - axial-leaded, through-hole mountable package with 0.4g mass and UL 94V-0 rating |
| Thermal Resistance | RθJA = 75°C/W - determines junction temperature rise under steady-state power dissipation |
| Operating Temperature | -55°C to +175°C - enables use in under-hood automotive and industrial environments |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body (UL 94V-0), cathode band marking on unidirectional variant. Leads are solderable per MIL-STD-202, Method 208; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node in unidirectional configuration |
| Cathode | High-side transient input terminal | Connected to protected line; cathode band identifies polarity for correct orientation |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 4 surges (4kV/2Ω) on 12V systems |
| Glass-passivated junction | Reduces surface leakage and improves long-term stability in humid or contaminated environments |
| Fast response time (<1ns) | Clamps transients before sensitive logic or analog circuitry experiences overvoltage stress |
| RoHS-compliant lead finish | Meets EU Directive 2011/65/EU with full exemption documentation for high-reliability applications |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|
Use Scenario: Protects microcontroller GPIOs and CAN transceiver power rails from load-dump and ISO 7637-2 pulses in vehicle door modules. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between 12V supply rail and chassis ground. Use Value: Clamps 10.5V max during 57A surge, preserving 5V LDO input integrity and preventing brownout resets. | Use Scenario: Shields 24V digital input optocoupler front-end from field-wiring induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of series current-limiting resistor and input filter capacitor. Use Value: Limits transient voltage to ≤10.5V, ensuring optocoupler LED remains within safe forward voltage range during 1kV ring-wave events. |

IC Role / Device Role / Timing Role: Bidirectional-capable variant (P6KE6V8CA-T) used across differential pair with common-mode choke. Use Value: Limits differential-mode surge to ≤10.5V peak, preserving transceiver common-mode range and preventing latch-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8A-T | Same VRWM (6.8V) and VC (10.5V), but SMC package (surface-mount); 600W rating retained | Requires PCB redesign for SMD placement; better thermal performance due to lower RθJA (50°C/W) | Select when board space is constrained and reflow assembly is available |
| 1.5KE6.8A-T | Higher PPK (1500W), same DO-15 package; VRWM = 5.8V, VC = 10.5V, but larger physical size and higher cost | Overqualified for most 600W-use cases; used only where multi-pulse or repeated surge testing is required | Select only if system-level test requires >600W single-pulse margin or legacy 1.5KE footprint compatibility |
Compared with SMBJ6.8A-T and 1.5KE6.8A-T, P6KE6V8A-T provides optimal balance of proven through-hole manufacturability, cost efficiency, and sufficient surge immunity for standard automotive and industrial I/O protection - without over-engineering package size or power rating.

FAQ
What is the difference between P6KE6V8A-T and P6KE6V8CA-T?
P6KE6V8A-T is unidirectional, with cathode band marking and clamping only for positive transients relative to ground. P6KE6V8CA-T is bidirectional: no polarity marking, symmetric clamping for both polarities, enabling use on AC lines or differential buses like RS-485. Electrical specs (VRWM, VBR, VC) are identical, but IR is doubled for VR ≤10V bidirectional units per datasheet note 5.
Can P6KE6V8A-T be used in place of a Zener diode for voltage regulation?
No - P6KE6V8A-T is not designed for continuous regulation. It operates only during transient events and lacks tight VZ tolerance or stable dynamic impedance under DC bias. Its 6.45–7.14V VBR range and 1000μA IR at 5.8V VRWM make it unsuitable for precision reference or linear regulation; dedicated Zener diodes (e.g., BZX84-C6V8) must be used instead.
What is the maximum allowable PCB trace length between P6KE6V8A-T and the protected IC?
Trace inductance directly impacts clamping effectiveness. For sub-10V VC performance, total loop inductance (anode-to-ground + cathode-to-line) must remain ≤15nH. At typical PCB geometry, this limits trace length to ≤10mm per leg with 0.5mm width and ground plane underneath - verified via TDR measurement or SPICE simulation using manufacturer-provided parasitic models.
Is P6KE6V8A-T qualified to AEC-Q101 for automotive use?
No - the official Diodes datasheet states this part is obsolete and discontinued, with no AEC-Q101 qualification listed. While constructed in IATF 16949 facilities and RoHS compliant, it lacks formal automotive stress-test validation. For new automotive designs, Diodes recommends the AEC-Q101-qualified SMAJ6.8A or SMCJ6.8A series as drop-in replacements with full qualification documentation.
