Product details
Overview
P6SMB8.2AH from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 7.79–8.61 V, stand-off voltage of 7.02 V, and clamping voltage of 12.1 V at 52 A peak pulse current. It features AEC-Q101 qualification, glass passivated junction, and low leakage (<1 µA at 7.02 V), designed for automotive ESD and load-dump protection in power supply rails and signal lines.
For engineers reviewing the P6SMB8.2AH datasheet, P6SMB8.2AH pinout, P6SMB8.2AH application, or P6SMB8.2AH equivalent, key selection criteria include its DO-214AA (SMB) package compatibility, 150°C junction rating, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and verified clamping performance under 10/1000 µs transients.
Technical Context
The P6SMB8.2AH operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its minimum breakdown threshold (7.79 V). Its glass-passivated junction ensures stable VBR tolerance (±5.5%) and low leakage, while fast response (<1.0 ps) enables effective suppression of EFT and ISO 7637-2 pulses before downstream IC damage occurs.
Thermal design is supported by RθJC = 10°C/W and RθJA = 55°C/W, allowing reliable operation up to TJ = 150°C. The device uses a single-die DO-214AA (SMB) construction with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V - defines guaranteed conduction onset window under 10 mA test current |
| VWM | 7.02 V - maximum continuous reverse operating voltage without significant leakage |
| VC @ IPPM | 12.1 V at 52 A - clamped voltage during 10/1000 µs surge, limiting stress on protected circuitry |
| PPPSM | 600 W - non-repetitive peak pulse power handling per standard waveform |
| IR @ VWM | <1 µA - ultra-low leakage preserves battery life and signal integrity in standby |
| TJ max | 150°C - enables use in under-hood automotive environments and high-power industrial PCBs |
| Temp. Coeff. VBR | 0.065 %/°C - predictable VBR drift over temperature for robust system-level margining |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, single-ended unidirectional configuration with cathode band marking. Case meets UL 94V-0 flammability rating; terminals are matte tin-plated for reliable reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration |
| Cathode | Avalanche conduction terminal | Connected to protected line (e.g., 12 V rail or CAN bus); marked with band; conducts when line voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|

| Glass passivated junction | Ensures stable electrical parameters and long-term stability under humidity and thermal stress |
| ISO 7637-2 compliance | Meets Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (EFT) immunity requirements |
| Low-profile SMB package | Enables automated placement and fits space-constrained layouts typical in ADAS and body control modules |
| J-STD-020 Level 1 moisture sensitivity | Allows unlimited floor life and eliminates bake requirements prior to reflow assembly |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12 V battery-supplied ECUs exposed to load dump and jump-start surges. IC Role / Device Role: Unidirectional TVS placed between power rail and ground to clamp transients before they reach LDOs and microcontrollers. Use Value: Limits rail voltage to ≤12.1 V during 52 A 10/1000 µs pulses, preventing latch-up or burnout of downstream 16 V-rated regulators. | Use Scenario: Analog sensor outputs (e.g., pressure, temperature) routed across noisy motor drive zones. IC Role / Device Role: TVS on signal line to shunt ESD and coupled transients before reaching ADC input or op-amp buffer. Use Value: Clamps fast transients with <1 ps response, preserving signal fidelity and avoiding ADC saturation or reset events. |
| LED Lighting Driver Protection | USB/Serial Communication Line Protection |
Use Scenario: Constant-current LED drivers in automotive lighting subjected to PWM switching noise and cable discharge events. IC Role / Device Role: TVS across driver output to absorb inductive kickback and ESD from housing contact. Use Value: Withstands 600 W pulses and maintains VC ≤12.1 V, protecting MOSFET switches and current-sense resistors from overvoltage failure. | Use Scenario: RS-232 or UART lines connecting MCU to external diagnostics port exposed to user-handling ESD. IC Role / Device Role: Unidirectional TVS on TX/RX lines referenced to local ground to divert ±8 kV contact ESD per IEC 61000-4-2. Use Value: Sub-µA leakage avoids signal attenuation; 12.1 V clamping prevents damage to 3.3 V or 5 V level-shifters and transceivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | VBR = 8.89–9.82 V, VC = 12.7 V @ 47.2 A, same DO-214AA package | Higher VBR and VC reduce margin for 7–8 V systems but improve noise immunity | Select SMBJ8.0A if system nominal voltage is ≥8.5 V and higher clamping threshold is acceptable |
| 1.5SMC8.2A | VBR = 7.79–8.61 V, VC = 12.3 V @ 49 A, DO-214AB (SMC) package (larger footprint) | Larger SMC package increases board area but offers better thermal dissipation for repetitive surges | Choose 1.5SMC8.2A only when layout allows larger footprint and higher thermal mass is required |
Compared with P6SMB8.2AH, SMBJ8.0A provides tighter VBR tolerance but higher clamping, while 1.5SMC8.2A matches VBR closely but requires PCB redesign due to DO-214AB size-making P6SMB8.2AH optimal for space-constrained AEC-Q101 designs needing precise 7–8 V rail protection.

FAQ
What is the polarity configuration of the P6SMB8.2AH?
The P6SMB8.2AH is a unidirectional TVS diode, with cathode marked by a band on the DO-214AA (SMB) package. It conducts only when reverse voltage exceeds its breakdown range (7.79–8.61 V), making it suitable for DC rail protection where polarity is fixed. Bidirectional variants use "CAH" suffix (e.g., P6SMB8.2CAH).
Does the P6SMB8.2AH meet automotive qualification standards?
Yes, the P6SMB8.2AH is AEC-Q101 qualified and tested for temperature cycling, high-temperature reverse bias (HTRB), and ESD per JEDEC standards. It also complies with ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b, confirming suitability for automotive power net and signal line protection per OEM requirements.
What is the maximum clamping voltage of the P6SMB8.2AH under surge conditions?
The P6SMB8.2AH has a maximum clamping voltage (VC) of 12.1 V at 52 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected circuitry sees no more than 12.1 V during worst-case transient events.
Can the P6SMB8.2AH be used in bidirectional applications?
No-the P6SMB8.2AH is unidirectional only. For bidirectional transient suppression (e.g., AC lines or differential buses), the designated variant is P6SMB8.2CAH, which features symmetrical breakdown in both directions and uses the same DO-214AA package with different marking (KVK).
What is the leakage current specification for the P6SMB8.2AH at its stand-off voltage?
At its rated stand-off voltage (VWM) of 7.02 V, the P6SMB8.2AH exhibits a maximum reverse leakage current (IR) of less than 1 µA at 25°C. This ultra-low leakage supports energy-sensitive applications such as always-on automotive modules and battery-backed sensor nodes.
