Product details
Overview
P6SMB75CH from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode designed for automotive-grade ESD and surge protection in power rails and signal lines. It features a standoff voltage of 60.7 V, breakdown voltage range of 67.5–82.5 V at 1 mA, clamping voltage of 108 V at 5.8 A peak pulse current, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the P6SMB75CH datasheet, P6SMB75CH pinout, P6SMB75CH application, or P6SMB75CH equivalent, this device serves as a robust, low-profile solution for ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, fast-response (<1.0 ps) transient suppression, and high-reliability protection of CAN, LIN, and sensor interfaces in automotive electronics.
Technical Context
The P6SMB75CH is a unidirectional/bidirectional TVS diode configured as a single die in DO-214AA (SMB) package, with glass-passivated junction and matte tin-plated leads compliant with J-STD-002 solderability. Its bipolar construction enables symmetrical clamping in both directions, supporting bidirectional transients without polarity sensitivity.
It delivers 600 W non-repetitive peak pulse power (10/1000 µs waveform), operates across –55 °C to +150 °C junction temperature range, and exhibits <1 µA reverse leakage at 60.7 V, with thermal resistance RθJA = 55 °C/W and RθJC = 10 °C/W - enabling reliable thermal performance in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60.7 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin for protected line |
| VBR (min/max) | 67.5 V / 82.5 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events |
| VC @ IPPM | 108 V at 5.8 A - Clamping voltage under 10/1000 µs surge; limits downstream IC stress to ≤108 V |
| PPPSM | 600 W - Peak pulse power rating; supports high-energy transients per ISO 7637-2 without failure |
| IR @ VWM | <1 µA - Ultra-low reverse leakage; prevents standby current drain in battery-powered systems |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments |
| Package | DO-214AA (SMB) - Surface-mount, low-profile outline compatible with automated placement and reflow |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with cathode band marking; polarity-sensitive for unidirectional variants, but P6SMB75CH is bidirectional - no functional polarity distinction; terminals are symmetric anode/cathode connections.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Transient return path (bidirectional) | Accepts positive or negative surge energy; connects to protected line or ground reference depending on layout |
| Cathode (K) | Transient return path (bidirectional) | Electrically identical to Anode in bidirectional configuration; used for mechanical mounting and symmetry in PCB footprint |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, humidity, and mechanical shock per JESD22 standards |
| Glass passivated junction | Enhances long-term reliability and moisture resistance vs. epoxy-passivated alternatives |
| ISO 7637-2 compliance | Meets Pulse 1 (inductive load dump), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (switching noise) requirements |
| Fast response time | <1.0 ps rise time from 0 V to VBR(min); ensures clamping before sensitive ICs experience overstress |
| Moisture sensitivity level 1 | No floor life limitation; suitable for standard SMT assembly without dry-pack or baking requirements |
Applications
| Automotive Power Rail Protection | CAN/LIN Bus Transient Suppression |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping element placed between power rail and chassis ground.

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 | Same DO-214AA package, 600 W rating, VBR = 75–83.3 V, VC = 121 V @ 4.95 A; higher clamping voltage than P6SMB75CH | Higher clamping increases risk of downstream IC overstress in tight-margin designs | Select when legacy design uses SMBJ series or requires tighter VBR tolerance (±5% vs. P6SMB75CH's ±7.5%) |
| 1.5KE75CA | Through-hole DO-15 package, same 75 V nominal, VC = 121 V @ 4.95 A; lower thermal resistance (RθJA ≈ 30 °C/W) but incompatible with SMT automation | Not suitable for high-density automotive PCBs requiring full surface-mount assembly | Prefer only for prototyping, repair, or legacy through-hole systems where rework flexibility outweighs production efficiency |
Compared with SMBJ75CA and 1.5KE75CA, the P6SMB75CH offers lower clamping voltage (108 V vs. 121 V), AEC-Q101 qualification, and SMB package compatibility with high-speed pick-and-place - making it optimal for new automotive electronics requiring robust, automated, and space-constrained surge protection.

FAQ
What is the polarity configuration of P6SMB75CH?
The P6SMB75CH is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without polarity dependency. Unlike unidirectional variants (e.g., P6SMB75H), it has no cathode band designation and functions identically regardless of terminal orientation in circuit layout.
Does P6SMB75CH meet AEC-Q101 requirements?
Yes, P6SMB75CH is explicitly AEC-Q101 qualified per the manufacturer's datasheet (Version A2102). This includes stress testing for temperature cycling, high-temperature operating life, unbiased highly accelerated stress test (UHAST), and mechanical shock - confirming suitability for automotive under-hood applications.
What is the maximum clamping voltage of P6SMB75CH under surge conditions?
The maximum clamping voltage of P6SMB75CH is 108 V, measured at 5.8 A peak pulse current using the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events.
Can P6SMB75CH replace P6SMB75H in existing designs?
No - P6SMB75CH is bidirectional while P6SMB75H is unidirectional. Substituting P6SMB75CH for P6SMB75H may cause unintended conduction in DC-biased circuits. The CH suffix denotes bipolar functionality; always verify system-level polarity requirements and transient directionality before replacement.
What packaging and reel quantity is offered for P6SMB75CH?
P6SMB75CH is supplied in DO-214AA (SMB) package on tape-and-reel format, with 3,000 units per reel. The tape meets EIA-481 standards and supports high-speed automated placement equipment used in automotive electronics manufacturing.
