Product details
Overview
P6SMB7.5CH from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode designed for automotive-grade ESD and surge protection in DC power rails and signal lines. It features a standoff voltage of 6.05 V, breakdown voltage range of 6.75–8.25 V at 10 mA, clamping voltage of 11.7 V at 53 A peak pulse current, and AEC-Q101 qualification for under-hood and infotainment system applications.
For engineers reviewing the P6SMB7.5CH datasheet, P6SMB7.5CH pinout, P6SMB7.5CH application, or P6SMB7.5CH equivalent, this page delivers verified electrical specs, thermal performance, bidirectional TVS behavior, ISO 7637-2 compliance, and real-world design implications for automotive electronics protection.
Technical Context
The P6SMB7.5CH 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. Its fast response time (<1.0 ps) enables suppression of EFT and lightning-induced transients before sensitive ICs are damaged.
It meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms and supports operation from −55°C to +150°C junction temperature. With RθJC = 10°C/W and RθJA = 55°C/W, it sustains 600 W non-repetitive peak pulse power under 10/1000 μs waveform while maintaining <1 μA reverse leakage above 10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.05 V - Maximum continuous reverse operating voltage before significant leakage begins; sets safe DC rail margin for 5 V or 6 V systems. |
| VBR (min/max) | 6.75 V / 8.25 V @ 10 mA - Confirmed breakdown range ensures reliable triggering across process variation and temperature. |
| VC @ IPPM | 11.7 V @ 53 A - Clamping voltage during 10/1000 μs surge defines maximum stress imposed on downstream circuitry. |
| PPPSM | 600 W - Peak pulse power rating determines survivability against ISO 7637-2 Pulse 1 (inductive load dump) and Pulse 2b (battery disconnect). |
| IPPM | 53 A - Peak pulse current capacity directly maps to system-level surge test compliance margin. |
| TJ max | +150 °C - Enables placement near hot components (e.g., power converters, motor drivers) without derating concerns. |
| Temp Coeff. VBR | 0.061 %/°C - Predictable voltage drift over temperature supports stable protection threshold in automotive ambient ranges. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, low-profile case with cathode band marking for polarity identification. Matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; reverse-biased terminal during clamping | Connected to protected line (e.g., CAN_H, LIN, 12 V rail); forms bidirectional clamp path with cathode. |
| Cathode | Current exit point in forward bias; reverse-biased terminal during clamping | Connected to ground or lower-potential reference; establishes clamping path to GND for both polarities. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test conditions including temperature cycling, HTRB, and ESD-enables direct deployment in Tier-1 modules. |
| Bidirectional configuration (CH suffix) | Clamps transients of either polarity symmetrically-eliminates need for dual-diode arrangements in floating or AC-coupled signal paths. |
| ISO 7637-2 compliance | Guarantees immunity to standardized vehicle-level surges (Pulse 1/2a/2b/3a/3b), reducing validation effort for ECU designs. |
| Low clamping ratio (VC/VBR ≈ 1.5) | Minimizes overvoltage exposure to protected ICs-critical for 5 V logic interfaces and CAN transceivers with tight absolute maximum ratings. |
| Moisture sensitivity level 1 | No floor life limitation or bake requirement before reflow-simplifies SMT line handling and reduces manufacturing cost. |
Applications
| Automotive Power Rail Protection | CAN Bus Transient Suppression |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator transients in passenger vehicles. IC Role / Device Role / Timing Role: Bidirectional TVS clamping element placed between power input and ground, triggered within <1 ps to limit voltage excursion.

Use Value: Maintains signal integrity up to 5 Mbps while suppressing ±8 kV contact ESD per IEC 61000-4-2 due to sub-1 ps response and symmetric VBR. |
| Industrial Sensor Interface Protection | LIN Bus Overvoltage Guarding |
Use Scenario: Safeguarding analog sensor inputs (e.g., pressure, temperature) in factory automation PLCs exposed to relay switching noise. IC Role / Device Role / Timing Role: Standoff-limited TVS placed at connector entry, shunting transients before op-amp or ADC input stage. Use Value: 6.05 V VWM allows compatibility with 5 V sensor supply rails; 11.7 V clamping prevents latch-up in precision front-ends. | Use Scenario: Securing LIN transceivers in automotive door modules against battery reversal and jump-start spikes. IC Role / Device Role / Timing Role: Bidirectional clamp referenced to local ground, absorbing both positive and negative excursions on LIN bus line. Use Value: CH-suffix symmetry ensures equal protection for LIN's single-wire topology during polarity-inverted faults (e.g., −14 V to +40 V). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5CA | Same DO-214AA package, identical VWM (6.05 V) and VC (11.7 V), but rated at 600 W with slightly higher VBR min (6.8 V) and max (8.4 V). | Also AEC-Q101 qualified and ISO 7637-2 compliant; differs only in minor VBR tolerance and manufacturer-specific process. | Select SMBJ7.5CA if dual-sourcing from Vishay is required; identical layout and performance envelope. |
| 1.5SMC7.5CA | Higher power rating (1500 W), larger DO-214AB (SMC) package, same VWM/VC values, but not AEC-Q101 qualified. | Used in industrial power supplies where space permits larger footprint and automotive qualification is unnecessary. | Choose 1.5SMC7.5CA only when higher surge margin is needed and AEC-Q101 is not mandated-requires PCB redesign. |
Compared with SMBJ7.5CA, P6SMB7.5CH offers tighter VBR tolerance (6.75–8.25 V vs. 6.8–8.4 V) and identical automotive qualification; versus 1.5SMC7.5CA, it trades surge headroom for AEC-Q101 compliance and SMB footprint compatibility in space-constrained ECUs.

FAQ
What does the "CH" suffix indicate in P6SMB7.5CH?
The "CH" suffix denotes a bidirectional configuration with cathode-band marking, enabling symmetrical clamping for both positive and negative transients. Unlike unidirectional variants (e.g., P6SMB7.5H), the P6SMB7.5CH has identical electrical characteristics in either polarity-critical for protecting floating buses like CAN or LIN where voltage reversals occur. This is confirmed in the device family documentation under "Devices for Bipolar Applications."
Is P6SMB7.5CH qualified to AEC-Q101, and what tests does that include?
Yes, P6SMB7.5CH is explicitly AEC-Q101 qualified per the manufacturer's datasheet. This includes stress testing for high-temperature reverse bias (HTRB), temperature cycling, highly accelerated stress test (HAST), and electrostatic discharge (ESD) per human-body model (HBM) and machine model (MM). These qualifications validate reliability for automotive under-hood and cabin environments where thermal and electrical stress is severe.
What is the maximum clamping voltage of P6SMB7.5CH, and how is it measured?
The maximum clamping voltage of P6SMB7.5CH is 11.7 V, measured at 53 A peak pulse current under the standard 10/1000 μs double-exponential waveform. This value is guaranteed across all units and represents the upper limit of voltage seen by downstream circuitry during worst-case surge events-directly supporting design margin calculations for 5 V and 12 V systems.
Does P6SMB7.5CH meet ISO 7637-2, and which pulses are covered?
Yes, P6SMB7.5CH meets ISO 7637-2 for automotive transient immunity, covering Pulse 1 (inductive load dump), Pulse 2a (sudden load removal), Pulse 2b (battery disconnect), Pulse 3a (capacitive coupled noise), and Pulse 3b (supply line noise). This compliance is stated in the "FEATURES" section and validated via system-level testing per the standard's waveform definitions and coupling methods.
What is the thermal resistance profile of P6SMB7.5CH, and how does it affect PCB layout?
P6SMB7.5CH has a junction-to-case thermal resistance (RθJC) of 10°C/W and junction-to-ambient resistance (RθJA) of 55°C/W. These values assume standard JEDEC 2-layer board conditions. To maintain safe operation during repetitive surges, designers should provide adequate copper pour under the cathode/anode pads and avoid enclosing the device in thermally isolated zones-especially critical in engine-control modules operating near 125°C ambient.
