Product details
Overview
P6SMB75C from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a breakdown voltage range of 67.5–82.5 V at 1 mA, clamps to ≤108 V at 5.8 A peak pulse current, and operates within –55°C to +150°C junction temperature range - ideal for automotive infotainment power inputs and industrial SMPS front-end protection.
For engineers reviewing the P6SMB75C datasheet, P6SMB75C pinout, P6SMB75C application, or P6SMB75C equivalent, key selection criteria include its DO-214AA (SMB) package compatibility, bidirectional clamping symmetry, 1.0 μA max reverse leakage at 60.7 V standoff, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and thermal resistance (RθJA = 55°C/W) for board-level thermal design.
Technical Context
The P6SMB75C implements a glass-passivated silicon avalanche junction optimized for fast transient suppression with sub-nanosecond response (<1.0 ps rise time from 0 V to VBR min). Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating systems without polarity constraints.
It delivers 600 W non-repetitive peak pulse power (10/1000 μs waveform), supports 100 A surge current (8.3 ms half-sine), and maintains stable VBR temperature coefficient of 0.105 %/°C - critical for consistent protection across wide ambient ranges in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 67.5 V / 82.5 V at IT = 1 mA - defines reliable avalanche initiation window under transient stress |
| VWM | 60.7 V - maximum continuous DC or RMS operating voltage before leakage exceeds 1 μA |
| VC @ IPPM | ≤108 V at 5.8 A - clamping voltage limiting downstream component stress during 10/1000 μs transients |
| PPPSM | 600 W - peak pulse power handling per single transient event per JEDEC/IEC standards |
| IR @ VWM | ≤1 μA - ensures negligible standby power loss and signal integrity in high-impedance circuits |
| TJ Range | –55°C to +150°C - validated operation across automotive under-hood and industrial control cabinet temperatures |
| RθJA | 55°C/W - enables thermal design margin estimation on standard FR-4 PCBs with minimal copper area |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, bi-directional, cathode band not applicable (symmetrical terminals).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient current path | Either terminal accepts surge current in either polarity - no orientation dependency during placement |
| Case (exposed metal) | Thermal conduction path | DO-214AA body provides primary heat dissipation route to PCB copper; no electrical isolation |
Key Features
| Feature | Design Value |
|---|---|
| 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 |
| Moisture sensitivity level | MSL Level 1 (per J-STD-020) - allows unlimited floor life and standard reflow without baking |
| RoHS & halogen-free | Compliant with EU RoHS Directive 2011/65/EU and IEC 61249-2-21 - suitable for green manufacturing and export |
| Fast response time | <1.0 ps from 0 V to VBR min - limits voltage overshoot before protection engages |
| Low leakage | <1 μA at VWM = 60.7 V - preserves battery life and avoids false triggering in low-power sensor nodes |
Applications
| Automotive Infotainment Power Input | Industrial SMPS Front-End |
|---|---|
Use Scenario: Protecting USB-C PD and LVDS video power rails in head units against load-dump transients and ESD events. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point to shunt surges before LDOs and PMICs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA (Bourns) | Identical DO-214AA package, same 67.5–82.5 V VBR, but rated at 600 W with 10/1000 μs waveform and 5.8 A IPPM; RθJA = 55°C/W | No functional difference in clamping behavior or thermal performance; identical ISO 7637-2 compliance | Select when dual-sourcing required or Bourns supply chain preference applies |
| 1.5SMC75CA (ON Semiconductor) | Same VBR, VC, and PPPSM, but in larger DO-214AB (SMC) package (7.11 × 6.22 mm vs. SMB's 4.57 × 3.94 mm); RθJA = 40°C/W | Higher thermal mass allows higher sustained surge duty cycles; requires PCB layout change due to larger footprint | Prefer for high-reliability industrial designs needing enhanced thermal margin, accepting larger board area |
Compared with SMBJ75CA and 1.5SMC75CA, the P6SMB75C offers identical electrical protection performance in the space-constrained DO-214AA (SMB) form factor - making it optimal for compact consumer and automotive modules where board real estate and automated placement efficiency are prioritized.

FAQ
What is the polarity configuration of the P6SMB75C?
The P6SMB75C is a bidirectional TVS diode, meaning it functions identically in both forward and reverse bias directions. Its marking code "MQJ" and "C" suffix confirm symmetrical clamping behavior - no anode/cathode orientation is required during PCB placement, unlike unidirectional variants such as P6SMB75A.
Does the P6SMB75C meet automotive EMC standards?
Yes, the P6SMB75C meets ISO 7637-2 requirements for automotive transient immunity, including Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling). This validation is explicitly stated in the official Taiwan Semiconductor datasheet (Version Q2209) and supports use in automotive infotainment and body control modules.
What is the maximum clamping voltage of the P6SMB75C under surge conditions?
The P6SMB75C has a maximum clamping voltage (VC) of 108 V at 5.8 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures downstream components rated for ≤120 V are protected during transient events.
Can the P6SMB75C be used in place of a unidirectional TVS like P6SMB75A?
No - the P6SMB75C and P6SMB75A are not interchangeable without circuit review. The P6SMB75C is bidirectional and lacks polarity marking; the P6SMB75A is unidirectional with defined anode/cathode and lower forward voltage (VF = 5.0 V). Substituting one for the other may cause improper clamping or forward conduction in DC-biased rails.
What is the moisture sensitivity level (MSL) rating for the P6SMB75C?
The P6SMB75C is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and can undergo standard lead-free reflow profiles without pre-baking. This simplifies manufacturing logistics and eliminates moisture-related popcorning risk during SMT assembly.
