Product details
Overview
P6SMB7.5AH from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode designed for automotive-grade overvoltage protection in power rails and signal lines. It features a breakdown voltage range of 7.13–7.88 V at 10 mA, clamps transients to ≤11.3 V at 55 A peak pulse current, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b immunity requirements for vehicle electronics.
For engineers reviewing the P6SMB7.5AH datasheet, P6SMB7.5AH pinout, P6SMB7.5AH application, or P6SMB7.5AH equivalent, key selection criteria include its 6.40 V stand-off voltage, <1 μA reverse leakage at VWM, 1.0 ps response time, AEC-Q101 qualification, and DO-214AA (SMB) package compatibility with automated SMT assembly.
Technical Context
The P6SMB7.5AH operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast transient suppression with low capacitance and stable clamping behavior. Its thermal design supports 150°C maximum junction temperature and 10°C/W junction-to-case resistance, enabling reliable operation under repetitive surge stress in automotive ambient conditions.
It is rated for non-repetitive 10/1000 μs waveform pulses up to 600 W, with a 55 A peak pulse current capability and 11.3 V clamping voltage - ensuring robust protection for 5 V–12 V systems against ESD, load dump, and inductive switching transients without compromising signal integrity.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 5 V microcontroller supply rails in body control modules exposed to load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VCC and GND to clamp voltage excursions above 6.4 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 |
|---|---|---|---|
| SMBJ7.5A | Same DO-214AA package, identical VBR (7.13–7.88 V), but rated for 600 W per JEDEC standards; slightly higher VC (12.0 V) | Compatible with same PCB layout; marginally higher clamping may affect sensitive 5 V logic | Select SMBJ7.5A if sourcing from alternate suppliers with tighter inventory on SMBJ series |
| 1.5SMC7.5A | Larger DO-214AB (SMC) package; same electrical specs but higher thermal mass (RθJA = 40°C/W vs. 55°C/W) | Requires board redesign; better suited for high-temperature industrial environments where SMB thermal derating is limiting | Choose 1.5SMC7.5A only when thermal performance outweighs space constraints |
Compared with SMBJ7.5A and 1.5SMC7.5A, the P6SMB7.5AH offers identical electrical protection in a smaller DO-214AA footprint with AEC-Q101 validation - making it optimal for space-constrained, automotive-qualified designs requiring proven reliability under vibration and thermal cycling.

FAQ
What is the maximum clamping voltage of the P6SMB7.5AH under specified test conditions?
The P6SMB7.5AH has a maximum clamping voltage (VC) of 11.3 V when subjected to a 10/1000 μs waveform peak pulse current (IPPM) of 55 A. This value is measured at TA = 25°C and ensures downstream circuitry remains within safe operating limits during standardized surge events defined in ISO 7637-2. The P6SMB7.5AH maintains this clamping performance across its qualified temperature range.
Is the P6SMB7.5AH suitable for bidirectional transient protection?
No, the P6SMB7.5AH is a unidirectional TVS diode intended for protection of DC power rails and single-polarity signal lines. For bidirectional applications such as AC lines or data buses, the P6SMB7.5AH must be replaced with the bipolar variant P6SMB7.5CAH, which provides symmetrical clamping in both directions and uses a different marking code (KDJ → KGJ for unidirectional, KCH → KCG for bidirectional).
Does the P6SMB7.5AH meet automotive qualification standards?
Yes, the P6SMB7.5AH is AEC-Q101 qualified and explicitly tested to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b transient immunity requirements. Its construction includes glass-passivated junctions, moisture sensitivity level 1 handling, and JESD 201 Class 2 whisker resistance - all essential for deployment in automotive control units, infotainment systems, and ADAS modules.
What is the stand-off voltage (VWM) and why does it matter for the P6SMB7.5AH?
The P6SMB7.5AH has a stand-off voltage (VWM) of 6.40 V, meaning it remains in high-impedance blocking mode up to this reverse voltage with leakage <1 μA. This parameter is critical for protecting 5 V systems: it allows normal operation without loading the rail, while ensuring rapid avalanche conduction begins just above nominal voltage - minimizing false triggering and maximizing noise immunity.
Can the P6SMB7.5AH be used in high-humidity or under-hood automotive environments?
Yes, the P6SMB7.5AH is qualified for operation from –55°C to +150°C and features a UL 94V-0 compliant molding compound with moisture sensitivity level 1 - eliminating pre-bake requirements and ensuring reliability in humid, thermally aggressive under-hood locations. Its glass-passivated junction and matte tin-plated leads further enhance resistance to corrosion and intermetallic growth during extended service life.
