Product details
Overview
P6SMB62CA from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor diode designed for robust overvoltage protection in DC power rails and signal lines. It features a standoff voltage of 53.0 V, breakdown voltage range of 58.9–65.1 V at 1 mA, clamping voltage of 85.0 V at 7.4 A peak pulse current, and operates within -55°C to +150°C junction temperature range - deployed in switching mode power supplies and industrial adapters.
For engineers reviewing the P6SMB62CA datasheet, P6SMB62CA pinout, P6SMB62CA application, or P6SMB62CA equivalent, key selection criteria include bidirectional clamping performance under ISO 7637-2 Pulse 1/2a/2b/3a/3b, low leakage (<1 µA @ 53.0 V), fast sub-1 ps response, and DO-214AA (SMB) surface-mount compatibility with automated placement.
Technical Context
The P6SMB62CA implements a glass-passivated silicon avalanche junction optimized for unidirectional or bidirectional transient suppression without external polarity constraints. Its symmetrical I-V characteristics enable identical clamping behavior in both directions, validated per ANSI/IEEE C62.35 and compliant with ISO 7637-2 test pulses.
Thermal design relies on RθJC = 10°C/W and RθJA = 55°C/W, supporting continuous operation up to 150°C junction temperature. The device sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits <1 µA reverse leakage above its 53.0 V standoff voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 53.0 V - Maximum continuous reverse operating voltage before significant leakage begins |
| VBR (min/max) | 58.9 V / 65.1 V at 1 mA - Ensures reliable avalanche initiation across process variation |
| VC @ IPPM | 85.0 V at 7.4 A - Clamped voltage during 10/1000 µs surge defines protected circuit stress level |
| PPPSM | 600 W - Peak pulse power handling capacity per single 10/1000 µs waveform |
| IR @ VWM | <1 µA - Ultra-low leakage preserves efficiency in high-impedance bias networks |
| TJ Range | -55°C to +150°C - Enables deployment in automotive under-hood and industrial ambient environments |
| Package | DO-214AA (SMB) - Standardized surface-mount outline compatible with IPC-7351B land patterns |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band; weight ≈ 0.090 g; UL 94V-0 rated compound; JESD201 Class 2 whisker resistant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Cathode Band Side) | Reference terminal for bidirectional conduction | Marked end serves as common reference; symmetric structure enables equal clamping in either direction |
| Cathode (Opposite Cathode Band) | Reference terminal for bidirectional conduction | Unmarked end completes symmetrical terminal pair; no functional distinction between terminals |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM performance in both polarities - eliminates orientation sensitivity during placement |
| ISO 7637-2 compliance | Validated against Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) - meets automotive EMC requirements |
| Sub-1 ps response time | Typically <1.0 ps from 0 V to VBR(min) - intercepts fast ESD and lightning-induced transients before downstream IC damage |
| Glass passivated junction | Enhanced reliability and stable VBR tolerance over temperature and lifetime - reduces parameter drift in harsh environments |
| Moisture sensitivity Level 1 | No floor life limitation or bake requirement prior to reflow - simplifies SMT line integration and inventory management |

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 (Bourns) | 64 V VWM, 70.1 V VC @ 7.1 A, same DO-214AA package | Slightly higher clamping voltage and lower peak pulse current (600 W maintained); tighter VBR tolerance (±5% vs ±6.5% for P6SMB62CA) | Select when tighter VBR consistency or legacy Bourns qualification is required; verify layout compatibility with identical SMB footprint. |
| 1.5SMC68CA (ON Semiconductor) | 68 V VWM, 104 V VC @ 5.8 A, DO-214AB (SMC) package - larger than SMB | Higher clamping voltage and physically larger package increases board area and thermal mass; not drop-in compatible | Choose only if higher working voltage margin is needed and PCB space allows SMC footprint; requires layout revision. |
Compared with SMBJ64CA and 1.5SMC68CA, the P6SMB62CA offers optimal balance of low clamping (85.0 V), precise 53.0 V standoff, and minimal SMB footprint - making it preferred for space-constrained, high-density power supply layouts requiring ISO 7637-2 compliance.

FAQ
What does the "CA" suffix indicate in P6SMB62CA?
The "CA" suffix denotes a bidirectional configuration: the P6SMB62CA provides symmetrical clamping in both forward and reverse directions, unlike unidirectional "A" variants. This eliminates polarity concerns during PCB placement and supports differential-line protection without additional routing complexity. The P6SMB62CA achieves identical VBR, VC, and IPPM specifications regardless of voltage polarity applied across its terminals.
Is P6SMB62CA compliant with automotive EMC standards?
Yes, the P6SMB62CA is explicitly tested and compliant with ISO 7637-2 for automotive transient immunity, covering Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling). Its 600 W peak pulse rating, 85.0 V clamping voltage, and sub-1 ps response ensure robust protection of ECUs and power modules in 12 V and 24 V vehicle electrical systems - confirmed in Taiwan Semiconductor's Q2209 specification document.
What is the maximum clamping voltage of P6SMB62CA under surge conditions?
The maximum clamping voltage of P6SMB62CA is 85.0 V, measured at 7.4 A peak pulse current using the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuits during worst-case transients and is guaranteed across the full operating temperature range (-55°C to +150°C). The P6SMB62CA maintains this clamping performance bidirectionally, ensuring consistent protection regardless of surge polarity.
Can P6SMB62CA replace P6SMB62A in an existing design?
No - P6SMB62CA and P6SMB62A are functionally distinct: P6SMB62A is unidirectional (cathode-marked), while P6SMB62CA is bidirectional (no polarity marking). Substituting P6SMB62CA for P6SMB62A may cause unintended conduction in reverse-biased circuits. The P6SMB62CA must be used only where symmetrical clamping is required and board layout accommodates non-polarized placement. Always verify schematic and layout alignment before replacement.
What is the junction-to-ambient thermal resistance (RθJA) of P6SMB62CA?
The junction-to-ambient thermal resistance of P6SMB62CA is 55°C/W under standard JEDEC test conditions (single device on FR-4 board with 1-inch² copper pad). This value governs temperature rise during sustained power dissipation and informs derating curves for elevated ambient temperatures. When used in high-density layouts or enclosed enclosures, actual RθJA may increase; thermal simulation or empirical testing with the P6SMB62CA is recommended for critical thermal margins.
