Product details
Overview
P6KE68CHE3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 68 V breakdown voltage (VBR min = 64.6 V, max = 71.4 V), 92.0 V maximum clamping voltage at 6.5 A peak pulse current, 600 W peak pulse power rating (10/1000 µs waveform), and AEC-Q101 qualification for automotive-grade reliability - deployed in ECU power input stages and sensor interface protection.
For engineers reviewing the P6KE68CHE3/73 datasheet, P6KE68CHE3/73 pinout, P6KE68CHE3/73 application, or P6KE68CHE3/73 equivalent, key selection criteria include its bi-directional clamping behavior, DO-204AC (DO-15) package compatibility, low 0.104 %/°C temperature coefficient of VBR, and verified surge immunity per IEC 61000-4-5 Level 4 requirements in automotive infotainment and body control modules.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 58.1 V), but triggers into low-impedance conduction when transient voltage exceeds its 64.6–71.4 V breakdown range. Its glass-passivated junction ensures stable VBR tolerance and fast response (<1 ns), critical for suppressing ESD and load-dump spikes before downstream ICs are damaged.
Designed for bi-directional use, P6KE68CHE3/73 has no polarity marking and symmetric electrical characteristics in both directions. It sustains repetitive 10/1000 µs surges at 0.01 % duty cycle, with thermal resistance RθJL = 20 °C/W enabling reliable power dissipation without heatsinking in PCB-constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 64.6 V / 71.4 V - defines precise clamping onset window; ensures consistent protection margin above 58.1 V stand-off voltage |
| VC @ IPPM | 92.0 V @ 6.5 A - maximum clamped voltage during 10/1000 µs surge; guarantees downstream ICs see ≤92 V under worst-case transients |
| PPPM | 600 W - peak surge power handling capability; supports IEC 61000-4-5 4 kV/2 Ω coupling network compliance |
| IPPM | 6.5 A - peak pulse current capacity; determines minimum series impedance required to limit fault energy in protected circuit |
| VWM | 58.1 V - maximum continuous reverse working voltage; sets upper limit for safe DC rail operation without leakage-induced heating |
| TJ max | 175 °C - maximum junction temperature; enables operation in under-hood automotive environments with minimal derating |
| Temp. Coeff. (VBR) | 0.104 %/°C - quantifies VBR drift with temperature; allows accurate clamping prediction across -55 °C to +175 °C range |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point in bi-directional configuration | Acts as cathode during positive transients; forms symmetrical clamping path with cathode terminal |
| Cathode | High-side connection point in bi-directional configuration | Acts as anode during negative transients; enables full-cycle voltage clamping without polarity dependency |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, ADAS sensors, and infotainment power inputs |
| Glass passivated junction | Ensures stable VBR tolerance (±5 %) and long-term reliability under thermal cycling and humidity stress |
| 600 W peak pulse power (10/1000 µs) | Supports Level 4 surge immunity (4 kV line-to-ground, 2 kV line-to-line) per IEC 61000-4-5 without external current limiting |
| Bi-directional symmetry | Eliminates need for polarity-aware layout; simplifies PCB routing on bidirectional buses like CAN FD or LIN |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), critical for protecting high-speed interfaces |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamping |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator ripple.

| Consumer Device USB Port Surge Suppression | Telecom DSL Line Transient Filtering |
Use Scenario: Adding secondary overvoltage protection on USB VBUS lines in portable docking stations subjected to hot-plug inductive kickback. IC Role / Device Role / Timing Role: Standby-mode TVS connected between VBUS and GND, activated only during >58.1 V excursions. Use Value: Complements primary protection (e.g., polymer PTC + ceramic capacitor) by clamping residual overshoot below USB 2.0 5.5 V absolute max rating. |
Use Scenario: Front-end protection for ADSL/VDSL line drivers interfacing with unshielded twisted-pair telephone lines vulnerable to lightning-induced surges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower 600 W rating same, but SMB package (smaller footprint); VC = 103 V @ 5.8 A; higher thermal resistance (RθJA = 110 °C/W) | Better suited for space-constrained consumer PCBs; less effective in sustained surge scenarios due to inferior thermal dissipation | Select SMBJ64CA only when board area is critical and surge repetition rate is low (e.g., single-event ESD in handheld devices) |
| 1.5KE68CA | Same DO-15 package and 68 V rating, but 1500 W peak power; VC = 112 V @ 13.4 A; larger junction area increases capacitance (≈150 pF vs. ≈50 pF) | Preferred for high-energy lightning surge zones (e.g., telecom demarcation points); excessive capacitance limits use in >10 MHz signal paths | Choose 1.5KE68CA where IEC 61000-4-5 Level 5 (6 kV) compliance is mandatory and signal bandwidth <1 MHz permits higher junction capacitance |
Compared with SMBJ64CA and 1.5KE68CA, P6KE68CHE3/73 delivers optimal balance of automotive-grade reliability (AEC-Q101), compact DO-15 form factor, and predictable 92 V clamping - making it the preferred choice for cost-sensitive, thermally constrained, and medium-surge automotive and industrial control applications.

FAQ
What is the meaning of the 'HE3' and '/73' suffixes in P6KE68CHE3/73?
The 'HE3' suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. The '/73' denotes packaging in 13-inch paper tape and reel, standard for automated SMT placement. P6KE68CHE3/73 thus combines automotive-grade reliability, regulatory compliance, and production-ready packaging - essential for Tier 1 automotive suppliers using P6KE68CHE3/73 in safety-critical modules.
How does P6KE68CHE3/73 differ from uni-directional P6KE68A variants?
P6KE68CHE3/73 is bi-directional with symmetric clamping in both polarities and no cathode band marking, whereas P6KE68A is uni-directional with a visible cathode band and conducts only in reverse bias. P6KE68CHE3/73 is specified for applications like AC-coupled signal lines or bidirectional buses (e.g., CAN), while P6KE68A suits DC power rails where polarity is fixed. Both share identical VBR, VC, and PPPM ratings.
Can P6KE68CHE3/73 be used in place of P6KE68CA?
Yes - P6KE68CHE3/73 is the AEC-Q101-qualified, RoHS-compliant version of P6KE68CA. The 'HE3' suffix confirms enhanced reliability testing and whisker resistance, while electrical parameters (VBR, VC, PPPM) remain identical. P6KE68CHE3/73 is fully interchangeable with P6KE68CA in designs requiring automotive qualification or stricter process controls, with no layout or schematic changes needed.
What is the maximum allowable mounting temperature for P6KE68CHE3/73 during reflow soldering?
P6KE68CHE3/73 supports lead-free reflow per J-STD-020, with peak temperature up to 260 °C for ≤10 seconds. Its matte tin-plated leads comply with J-STD-002 for solderability, and the DO-204AC epoxy body withstands thermal shock without delamination. For optimal long-term reliability, maintain preheat ramp rate ≤3 °C/s and avoid exceeding 260 °C - critical when integrating P6KE68CHE3/73 into high-density automotive PCB assemblies.
Does P6KE68CHE3/73 meet IEC 61000-4-2 ESD immunity requirements?
P6KE68CHE3/73 is not rated for direct IEC 61000-4-2 contact discharge (e.g., ±8 kV) as a standalone device due to its 600 W rating optimized for longer-duration surges (10/1000 µs). However, it effectively suppresses ESD-induced secondary transients when used downstream of dedicated ESD arrays. System-level validation with P6KE68CHE3/73 in combination with upstream ESD protection is required to achieve full IEC 61000-4-2 compliance in automotive and industrial end equipment.
