Product details
Overview
P6SMB62CAH from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 58.9–65.1 V, clamping voltage of 85.0 V at 7.4 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability. It features glass-passivated junction, <1 μA reverse leakage above 53.0 V, and sub-1 ps response time, deployed in power supply input protection and CAN bus interface surge suppression.
For engineers reviewing the P6SMB62CAH datasheet, P6SMB62CAH pinout, P6SMB62CAH application, or P6SMB62CAH equivalent, key selection criteria include bidirectional clamping capability, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, DO-214AA (SMB) package thermal resistance (RθJA = 55 °C/W), and moisture sensitivity level 1 per J-STD-020.
Technical Context
The P6SMB62CAH operates as a bidirectional avalanche diode, symmetrically clamping transients in both polarities with identical VBR, VC, and IPPM specifications in forward and reverse directions. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA @ 53.0 V).
Designed for high-energy transient suppression, it delivers 600 W non-repetitive peak pulse power (10/1000 µs waveform) with fast response (<1 ps rise time) and meets automotive EFT immunity requirements per ISO 7637-2 across all defined pulses (1, 2a, 2b, 3a, 3b).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V - Ensures reliable avalanche conduction onset within tight tolerance for consistent clamping behavior |
| VWM | 53.0 V - Maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 85.0 V @ 7.4 A - Clamped voltage during 600 W transient, limiting downstream IC stress to safe levels |
| IPPM | 7.4 A - Peak pulse current supported under 10/1000 µs waveform, defining surge handling capacity |
| PPPSM | 600 W - Non-repetitive peak pulse power rating, critical for automotive load dump and inductive switching events |
| TJ max | +150 °C - Enables operation in under-hood automotive environments without derating |
| Package | DO-214AA (SMB) - Surface-mount footprint compatible with automated assembly and provides 0.090 g mass for thermal inertia |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band (bidirectional operation uses symmetrical terminal roles).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient conduction path | Either terminal serves as anode or cathode depending on transient polarity; no fixed polarity required in circuit layout |
| Case | Thermal and mechanical anchor | Non-electrical; provides mechanical stability and aids heat dissipation via PCB copper area |
Key Features

|---|---|
| AEC-Q101 qualified | Validated for automotive applications including temperature cycling, HTRB, and ESD testing per stress test plan |
| Glass-passivated junction | Ensures long-term parameter stability and low leakage drift over lifetime and temperature extremes |
| ISO 7637-2 compliance | Guarantees robustness against real-world automotive transients: Pulse 1 (inductive load dump), Pulse 2a/2b (switching spikes), Pulse 3a/3b (EFT) |
| Moisture sensitivity level 1 | Enables unlimited floor life before reflow; no baking required prior to assembly |
| RθJA = 55 °C/W | Supports thermal design with standard 1 oz copper PCB pads; enables 3 W steady-state dissipation at TA = 25 °C |

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 | VBR = 60.8–67.2 V; VC = 103 V @ 5.8 A; same DO-214AA package | Higher clamping voltage reduces margin for 60 V-rated downstream ICs | Select when higher VWM (55.0 V) is required and clamping margin allows |
| 1.5KE68CA | Through-hole DO-15 package; VBR = 58.0–64.0 V; VC = 98 V @ 6.1 A; PPPM = 1500 W | Not SMT-compatible; larger footprint and higher inductance limits high-speed transient response | Choose only for legacy through-hole designs requiring higher peak power |
Compared with SMBJ64CA and 1.5KE68CA, the P6SMB62CAH offers tighter VBR tolerance (±5.5%), lower clamping voltage (85.0 V vs. ≥98 V), and AEC-Q101 qualification-making it optimal for space-constrained, automotive-compliant SMT designs where precise voltage limiting and reliability are critical.

The P6SMB62CAH has a minimum breakdown voltage (VBR) of 58.9 V and a maximum of 65.1 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight ±5.5% tolerance ensures predictable clamping onset and supports robust design margins in automotive power rail protection circuits using the P6SMB62CAH.
Is P6SMB62CAH suitable for bidirectional transient suppression?
Yes, the "CAH" suffix explicitly denotes bidirectional configuration. The P6SMB62CAH provides symmetrical clamping in both polarities, with identical VBR, VC, and IPPM values regardless of voltage polarity-making it ideal for differential signal lines like CAN bus or AC-coupled interfaces where transients may swing positive or negative relative to ground.
What is the maximum clamping voltage of P6SMB62CAH under surge conditions?
The P6SMB62CAH clamps to a maximum of 85.0 V at its rated peak pulse current of 7.4 A (10/1000 µs waveform). This value is guaranteed across temperature and production lot, enabling accurate overvoltage margin analysis for downstream components such as DC-DC controllers, microcontrollers, or transceivers in systems protected by the P6SMB62CAH.
Does P6SMB62CAH meet automotive qualification standards?
Yes, the P6SMB62CAH is AEC-Q101 qualified and certified for automotive use. It passes stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per the AEC-Q101 standard, and additionally complies with ISO 7637-2 for automotive transient immunity-confirming its suitability for engine control, body electronics, and infotainment systems using the P6SMB62CAH.
What package type and mounting method does P6SMB62CAH use?
The P6SMB62CAH uses the DO-214AA (SMB) surface-mount package with matte tin-plated leads compliant with J-STD-002 solderability requirements. It is designed for reflow soldering in automated assembly lines, supports tape-and-reel packaging (3,000 pcs per reel), and features a low-profile form factor ideal for dense PCB layouts where the P6SMB62CAH is deployed.
