Product details
Overview
P6SMB62CAHE3_A/H 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 62 V breakdown voltage (VBR min/max = 58.9–65.1 V), 600 W peak pulse power (10/1000 µs), and clamps to ≤85.0 V at 7.1 A peak pulse current - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6SMB62CAHE3_A/H datasheet, P6SMB62CAHE3_A/H pinout, P6SMB62CAHE3_A/H application, or P6SMB62CAHE3_A/H 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 TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at 53.0 V stand-off), while the low incremental surge resistance supports fast energy diversion during ESD or lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (peak reflow 260 °C), making it suitable for high-reliability automated SMT assembly. Its thermal resistance (RθJA = 100 °C/W) reflects standard SMB pad layout performance without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V - defines guaranteed clamping onset range under 1 mA test current; determines minimum overvoltage threshold before conduction. |
| VWM | 53.0 V - maximum continuous reverse operating voltage; must exceed normal signal swing to avoid leakage or power loss. |
| VC @ IPPM | 85.0 V @ 7.1 A - clamped voltage during 600 W transient; sets worst-case stress on downstream ICs during surge events. |
| PPPM | 600 W - peak pulse power handling (10/1000 µs waveform); validates robustness against IEC 61000-4-5 line surge tests. |
| IPPM | 7.1 A - derived peak pulse current at VC; used to size PCB trace width and verify system-level surge path integrity. |
| TJ max | 150 °C - maximum junction temperature; enables operation in under-hood automotive or enclosed industrial enclosures. |
| AEC-Q101 | Qualified - certified for automotive electronics per stress test requirements including HTOL, TCT, and ESD; supports PPAP documentation. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H), matte tin-plated terminals, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | Accepts surge current from either direction; connects to protected line (e.g., CAN_H or RS-485 A). |
| Cathode | Transient current exit (bidirectional) | Completes low-impedance path to ground or return rail; requires low-inductance PCB routing to GND plane. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Validates compliance with IEC 61000-4-5 Level 3 (1 kV line-to-ground) surge testing in industrial and automotive systems. |
| AEC-Q101 qualified (HE3 suffix) | Confirms reliability for automotive applications including body control modules, ADAS sensors, and infotainment interfaces. |
| Low clamping voltage (VC = 85.0 V) | Ensures protected ICs (e.g., microcontrollers, transceivers) remain below absolute maximum ratings during transients. |
| MSL Level 1 moisture sensitivity | Enables direct placement without baking; compatible with standard lead-free reflow profiles up to 260 °C peak. |
| Glass-passivated junction | Provides stable VBR tolerance and low leakage (<1 µA) across temperature and lifetime, critical for low-power sensor nodes. |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses in vehicle ECUs.

IC Role / Device Role / Timing Role: Line-side TVS connected across differential pair (A/B) and to ground, absorbing common-mode and differential-mode transients. Use Value: Maintains communication integrity by limiting voltage excursion to <85 V, avoiding receiver input saturation or bus lockup. |
| Consumer USB Port ESD | Telecom DSL Line Protection |
Use Scenario: ESD protection for USB 2.0 data lines (D+/D−) in set-top boxes and smart displays subjected to ±8 kV contact discharge per IEC 61000-4-2. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp placed directly at connector, shunting ESD current before reaching USB PHY. Use Value: Achieves pass/fail compliance without degrading 480 Mbps signal integrity due to minimal parasitic capacitance (<100 pF typical). | Use Scenario: Primary surge protection on DSL line cards handling asymmetric AC signals and lightning-induced longitudinal surges up to 10/700 µs. IC Role / Device Role / Timing Role: First-stage protector mounted at line entry, clamping mode-to-mode and mode-to-ground transients before transformer coupling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64CA | Same SMB package, 64 V VBR, 400 W PPPM, non-AEC-Q101 | Limited to commercial-grade industrial use; lacks automotive qualification and lower surge rating | Select when cost sensitivity outweighs AEC-Q101 requirement and 400 W suffices for system-level threat model. |
| 1.5KE68CA | Through-hole DO-201 package, 68 V VBR, 1500 W PPPM, no AEC-Q101 | Requires PCB redesign; higher power but incompatible with SMT production and space-constrained layouts | Choose only for legacy through-hole designs where board real estate and manual assembly are acceptable trade-offs. |
Compared with SMAJ64CA and 1.5KE68CA, P6SMB62CAHE3_A/H delivers AEC-Q101 qualification, precise 62 V clamping alignment with 5 V/3.3 V logic rails, and optimized SMB footprint for high-density automotive PCBs - making it the preferred choice where automotive compliance and surface-mount scalability are mandatory.

FAQ
What is the breakdown voltage tolerance for P6SMB62CAHE3_A/H?
The P6SMB62CAHE3_A/H has a specified breakdown voltage range of 58.9 V to 65.1 V at 1 mA test current (VBR min/max), corresponding to ±5% tolerance around the nominal 62 V rating. This tight distribution ensures predictable clamping behavior across production lots and supports reliable margining in safety-critical designs.
Is P6SMB62CAHE3_A/H suitable for automotive applications?
Yes, P6SMB62CAHE3_A/H is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS-compliant and automotive-grade construction. It is explicitly rated for under-hood and chassis-mounted applications, with validated performance across -65 °C to +150 °C junction temperature and compliance with automotive surge and ESD test standards.
What does the "CA" suffix mean in P6SMB62CAHE3_A/H?
The "CA" suffix in P6SMB62CAHE3_A/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VWM, and VC characteristics for forward and reverse bias. This eliminates polarity concerns during layout and simplifies protection of AC or differential signal lines.
How does P6SMB62CAHE3_A/H compare to unidirectional variants like P6SMB62AHE3_A/H?
P6SMB62CAHE3_A/H differs from unidirectional P6SMB62AHE3_A/H by offering symmetrical clamping in both directions and omitting the cathode band marking. Unidirectional versions support DC-biased lines with defined polarity and slightly higher IFSM (100 A), while the CA variant is mandatory for AC, differential, or polarity-agnostic protection such as USB or RS-485.
What is the maximum clamping voltage of P6SMB62CAHE3_A/H under surge conditions?
The maximum clamping voltage (VC) of P6SMB62CAHE3_A/H is 85.0 V at 7.1 A peak pulse current (IPPM), measured with a 10/1000 µs waveform. This value represents the worst-case voltage imposed on protected circuitry during a full-rated 600 W transient event and is critical for verifying downstream IC voltage tolerances.
