Product details
Overview
P6SMB68CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 68 V breakdown voltage (VBR min/max = 64.6–71.4 V), 600 W peak pulse power (10/1000 µs), and clamps to ≤92.0 V at 6.5 A peak pulse current - used in automotive sensor interface protection and industrial I/O line surge suppression.
For engineers reviewing the P6SMB68CAHE3_A/I datasheet, P6SMB68CAHE3_A/I pinout, P6SMB68CAHE3_A/I application, or P6SMB68CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMB (DO-214AA) package compatibility, and compliance with IEC 61000-4-2/4-4/4-5 transient immunity requirements.
Technical Context
This device operates as a voltage-clamping protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing ESD and lightning-induced surges on bidirectional data or supply rails.
Rated for 150 °C maximum junction temperature and MSL Level 1 moisture sensitivity, P6SMB68CAHE3_A/I supports reflow soldering up to 260 °C peak. The HE3 suffix confirms RoHS-compliant construction and AEC-Q101 qualification for automotive-grade reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 64.6–71.4 V at 1 mA test current - defines precise clamping onset threshold for bidirectional overvoltage events |
| Stand-off Voltage VWM | 58.1 V - maximum continuous working voltage before leakage exceeds 1 µA, ensuring no false triggering during normal operation |
| Clamping Voltage VC | ≤92.0 V at 6.5 A IPPM - actual voltage seen by protected circuit during 10/1000 µs surge, limiting stress on downstream ICs |
| Peak Pulse Power PPPM | 600 W (10/1000 µs waveform) - sustains high-energy transients without failure, suitable for IEC 61000-4-5 Level 3/4 compliance |
| Package | SMB (DO-214AA) - industry-standard 2-pin surface-mount outline with 5.0 mm × 5.0 mm copper pad thermal design support |
| AEC-Q101 Qualified | Yes - validated for automotive applications including engine control modules, ADAS sensor interfaces, and infotainment power rails |
| Thermal Resistance RθJA | 100 °C/W - enables thermal design with standard PCB copper area (0.2" × 0.2") without heatsink |
Pinout & Package

| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during transient events, improving margin for 75 V-rated components |
| MSL Level 1, 260 °C peak reflow | Compatible with standard lead-free SMT assembly processes without pre-baking or special handling |
| Glass passivated junction | Ensures stable leakage performance and long-term reliability under humidity and thermal cycling stress |
Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from ESD and load-dump transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point to shunt surge energy before reaching signal conditioning ICs. Use Value: Prevents latch-up or permanent damage to 5 V/12 V sensor interface ICs during ISO 10605 ±30 kV ESD or ISO 7637-2 pulse 5a load-dump events. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and 0–10 V analog inputs in programmable logic controllers against field-wiring induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on input terminals, coordinated with series current-limiting resistors and filtering capacitors. Use Value: Maintains signal integrity while meeting IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) Level 3 immunity requirements without adding active circuitry. |
| Telecom Line Card Surge Suppression | Consumer USB/DisplayPort ESD Protection |
Use Scenario: Front-end protection for Ethernet PHYs, DSL line drivers, and PoE-powered equipment exposed to lightning-induced surges on twisted-pair cables. IC Role / Device Role / Timing Role: First-stage transient suppressor on differential pairs, operating in parallel with GDTs or polymer PTCs for multi-level protection. Use Value: Limits induced common-mode voltage to <92 V during 10/1000 µs surges, preserving isolation barrier integrity and preventing PHY reset or damage. |
Use Scenario: Board-level ESD protection for USB 2.0/3.0 data lines and DisplayPort auxiliary channels in laptops and docking stations. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp placed adjacent to connector to absorb ±8 kV contact/±15 kV air IEC 61000-4-2 discharges. Use Value: Provides sub-nanosecond response with <1 pF junction capacitance (typ.) - avoids signal integrity degradation on high-speed differential links. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ68CA-E3/5B | Same 68 V bidirectional rating, but SMA package (smaller footprint, lower thermal mass); 400 W PPPM vs. 600 W | Preferred for space-constrained consumer PCBs where 400 W surge margin suffices; not AEC-Q101 qualified | Select when board area is critical and automotive qualification is unnecessary |
| SMCJ68CAHE3_A/I | Same AEC-Q101 qualification and HE3 suffix, but SMC package (larger, 1500 W PPPM); identical VBR, VC, and thermal specs | Used where higher surge robustness is required (e.g., battery rail protection), accepting larger footprint and cost | Select when system-level surge testing requires >600 W capability or extended thermal endurance |
Compared with P6SMB68CAHE3_A/I, SMAJ68CA-E3/5B offers smaller size at reduced surge rating, while SMCJ68CAHE3_A/I delivers higher power handling in a larger package - choice depends on PCB area constraints, required surge margin, and qualification scope.

FAQ
What does the "CA" suffix indicate in P6SMB68CAHE3_A/I?
The "CA" suffix denotes a bidirectional configuration - meaning P6SMB68CAHE3_A/I conducts and clamps symmetrically in both polarities, unlike unidirectional variants (e.g., P6SMB68A). This makes it suitable for protecting AC-coupled signals, differential buses, or supply rails where polarity reversal may occur during transients.
Is P6SMB68CAHE3_A/I suitable for IEC 61000-4-5 surge testing?
Yes, P6SMB68CAHE3_A/I is rated for 600 W peak pulse power with a 10/1000 µs waveform, which aligns with IEC 61000-4-5 Level 3 (1 kV line-to-earth, 2 kV line-to-line) and Level 4 (2 kV line-to-earth, 4 kV line-to-line) surge immunity requirements when properly mounted on recommended 5.0 mm × 5.0 mm copper pads.
How does the HE3 suffix affect P6SMB68CAHE3_A/I's compliance status?
The HE3 suffix confirms that P6SMB68CAHE3_A/I is RoHS-compliant and AEC-Q101 qualified - verified per automotive stress tests including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing. This qualifies it for use in automotive powertrain, body, and ADAS modules.
What is the maximum clamping voltage of P6SMB68CAHE3_A/I under surge conditions?
The maximum clamping voltage VC of P6SMB68CAHE3_A/I is 92.0 V at 6.5 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is guaranteed across temperature and represents the highest voltage imposed on protected circuitry during standardized surge events.
Can P6SMB68CAHE3_A/I replace unidirectional TVS diodes in existing designs?
No - P6SMB68CAHE3_A/I is strictly bidirectional and lacks polarity marking; substituting it for a unidirectional part (e.g., P6SMB68A) would compromise forward conduction behavior in DC-biased circuits. Use only where bidirectional clamping is explicitly required and circuit topology supports symmetrical protection.
