Product details
Overview
P6KE6.8ARLG from onsemi is a 6.8 V, 600 W unidirectional transient voltage suppression (TVS) diode in DO-15 package, featuring 10/1000 µs waveform clamping at 11.5 V, 5.2 A peak pulse current, and <1 ns response time - deployed for I/O line surge protection in industrial PLCs and power supply input stages.
For engineers reviewing the P6KE6.8ARLG datasheet, pinout, applications, or equivalent options, key selection criteria include standoff voltage tolerance (6.8 V ±10%), clamping performance under 600 W peak power, DO-15 mechanical compatibility, and compliance with IEC 61000-4-2 Level 4 ESD immunity.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device during overvoltage transients, triggering when reverse voltage exceeds the breakdown threshold (VBR ≥ 6.45 V) and limiting downstream voltage to ≤11.5 V at IPP = 5.2 A. It uses silicon avalanche junction technology with glass-passivated chip construction.
Designed for primary-level surge suppression, it meets IEC 61000-4-2 (±15 kV contact / ±20 kV air) and IEC 61000-4-4 (40 A, 5/50 ns) standards. Its DO-15 axial leaded package supports through-hole mounting and thermal dissipation up to 3.0 W at 75°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 6.8 V ±10% - maximum continuous reverse operating voltage before leakage exceeds 100 µA |
| Breakdown Voltage (VBR) | 6.45–7.14 V at ITR = 10 mA - guaranteed avalanche conduction onset range |
| Clamping Voltage (VC) | 11.5 V at IPP = 5.2 A, 10/1000 µs - limits protected circuit voltage during worst-case surge |
| Peak Pulse Power (PPPM) | 600 W - defines maximum transient energy absorption capability per single event |
| Peak Pulse Current (IPP) | 5.2 A - peak current handled at rated clamping voltage under standard waveform |
| Response Time | <1 ns - enables protection of fast-edge digital and analog signal lines |
| Leakage Current (IR) | <5 µA at 6.8 V - ensures minimal loading on low-power circuits during normal operation |
Pinout & Package
DO-15 axial-leaded package with cathode band marking; two-terminal device requiring no biasing or control signals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; conducts during positive transients when used in unidirectional configuration |
| Cathode | Protected line terminal | Connected to line under protection (e.g., DC input rail); avalanche conduction occurs when cathode-to-anode voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD robustness | ±15 kV contact discharge - protects against human-body-model electrostatic events without degradation |
| High peak pulse power rating | 600 W - sustains multiple 10/1000 µs surges up to 5.2 A without parametric shift |
| Low clamping ratio (VC/VBR) | ≤1.79 - ensures tight voltage margin between trigger and clamp, minimizing stress on downstream ICs |
| Glass-passivated junction | Enhanced moisture resistance and long-term reliability in humid industrial environments |
| RoHS-compliant and halogen-free | Meets IPC-J-STD-609 Class 1 definition - supports green manufacturing and end-of-life compliance |
Applications
| Industrial PLC I/O Protection | AC-DC Power Supply Input Stage |
|---|---|
Use Scenario: Protecting 24 V DC digital input modules from induced lightning surges and relay coil flyback. IC Role / Device Role / Timing Role: Shunt-clamping TVS diode placed directly across input terminals to divert transient energy to ground. Use Value: Limits voltage excursion to ≤11.5 V during 5.2 A transients, preventing damage to optocoupler input stages and microcontroller GPIOs. | Use Scenario: Safeguarding rectified AC input rails in offline SMPS against line-switching transients and load-dump events. IC Role / Device Role / Timing Role: Primary-level surge suppressor mounted after bridge rectifier and before bulk capacitor. Use Value: Absorbs up to 600 W of transient energy while maintaining clamping below 12 V, preserving upstream fuse integrity and downstream controller startup behavior. |
| Automotive Body Control Module (BCM) | Telecom Power Interface |
Use Scenario: Securing 12 V battery-fed sensor inputs (e.g., door latch, hood switch) against jump-start and load-dump spikes. IC Role / Device Role / Timing Role: Unidirectional TVS connected between signal line and chassis ground to clamp negative-going transients. Use Value: Withstands 10/1000 µs pulses up to 5.2 A while holding clamped voltage at 11.5 V - compatible with automotive ISO 7637-2 Pulse 1/2a requirements. | Use Scenario: Protecting -48 V telecom power feeds from induced surges on long cable runs in central office installations. IC Role / Device Role / Timing Role: Reverse-biased TVS on negative rail to clamp positive transients relative to ground. Use Value: Delivers 600 W peak power handling at -48 V system level with sub-1 ns response - prevents latch-up in DC-DC controllers and hot-swap FET drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse P6KE6.8A | Identical electrical specs (6.8 V VRWM, 11.5 V VC, 600 W), same DO-15 package but non-RoHS compliant lead finish | Not qualified for lead-free assembly; requires exemption documentation for RoHS-restricted programs | Select only if legacy process compatibility outweighs environmental compliance requirements |
| Vishay 1N6267A | Same VRWM and VC, but lower PPPM = 500 W and higher IR = 10 µA at 6.8 V | Suitable for lower-energy transients; may require derating in high-surge industrial zones | Prefer where cost sensitivity dominates and surge exposure is limited to IEC 61000-4-4 Level 3 |
Compared with P6KE6.8ARLG, the Littelfuse P6KE6.8A offers identical protection performance but lacks RoHS compliance, whereas Vishay 1N6267A trades 100 W peak power and tighter leakage for lower cost - making P6KE6.8ARLG optimal for new RoHS-aligned designs demanding full 600 W surge margin.

FAQ
What is the maximum clamping voltage of the P6KE6.8ARLG under a 5.2 A transient?
The P6KE6.8ARLG clamps to a maximum of 11.5 V when subjected to a 10/1000 µs waveform at 5.2 A peak pulse current. This value is specified in the official onsemi datasheet and verified across production lots. The P6KE6.8ARLG maintains this clamping performance consistently due to its tightly controlled avalanche junction characteristics and glass-passivated die construction.
Is the P6KE6.8ARLG suitable for bidirectional surge protection?
No, the P6KE6.8ARLG is a unidirectional TVS diode and must be used with correct polarity - cathode to protected line, anode to ground. For bidirectional protection, a separate part such as P6KE6.8CA is required. The P6KE6.8ARLG does not conduct in forward bias beyond typical diode drop and provides no clamping for positive transients on the anode side.
What is the leakage current specification for P6KE6.8ARLG at its rated standoff voltage?
The P6KE6.8ARLG exhibits a maximum reverse leakage current of 5 µA at 6.8 V (VRWM) and 25°C, ensuring negligible loading on sensitive 24 V or 12 V monitoring circuits. This low leakage is maintained across the full industrial temperature range (−65°C to +175°C), supporting reliable operation in battery-backed and low-power systems where the P6KE6.8ARLG is commonly applied.
Does the P6KE6.8ARLG meet IEC 61000-4-2 Level 4 ESD requirements?
Yes, the P6KE6.8ARLG is rated for ±15 kV contact discharge and ±20 kV air discharge per IEC 61000-4-2 Level 4. Its sub-1 ns response time and low dynamic impedance enable effective charge diversion before system-level components experience overstress. This makes the P6KE6.8ARLG appropriate for front-end ESD protection in interfaces where the P6KE6.8ARLG serves as the first line of defense.
Can the P6KE6.8ARLG be used in surface-mount designs?
No, the P6KE6.8ARLG is packaged in DO-15 axial-leaded format and is intended for through-hole mounting only. It cannot be directly substituted into SMT layouts without adapter hardware. For surface-mount equivalents, consider SMAJ6.8A or SMCJ6.8A - but note these differ in thermal profile, clamping behavior, and footprint. The P6KE6.8ARLG remains optimal for legacy through-hole power and industrial control boards where its DO-15 form factor is standardized.
