Product details
Overview
P6SMB82CH from Taiwan Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in DO-214AA (SMB) package, rated for 600W peak pulse power, 82V breakdown voltage (min 73.8V, max 90.2V), and clamps transients to ≤118V at 5.3A. It protects automotive and industrial control circuits against ISO 7637-2 Pulse 1/2a/2b/3a/3b surges.
For engineers reviewing the P6SMB82CH datasheet, P6SMB82CH pinout, P6SMB82CH application, or P6SMB82CH equivalent, key selection criteria include bidirectional clamping capability, 1.0mA test current, 66.4V stand-off voltage, <1μA leakage at VWM, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P6SMB82CH is a glass-passivated, unidirectional/bidirectional TVS diode with symmetrical clamping behavior in both polarities due to its CH suffix designation. Its junction exhibits low thermal resistance (RθJC = 10°C/W) and operates across –55°C to +150°C ambient range.
It delivers fast transient response (<1.0ps rise time from 0V to VBR min), meets JESD201 Class 2 whisker resistance, and complies with RoHS and halogen-free (IEC 61249-2-21) requirements. Moisture sensitivity level is J-STD-020 Level 1.
Key Specifications

|---|---|
| VBR (min/max) | 73.8V / 90.2V - Ensures reliable triggering above system operating voltage while accommodating manufacturing tolerance |
| VWM | 66.4V - Maximum continuous reverse working voltage before significant leakage begins |
| IPPM | 5.3A - Peak pulse current it can safely shunt during a 10/1000μs transient event |

| PPPSM | 600W - Non-repetitive peak pulse power handling per standard 10/1000μs waveform |
| ID@VWM | <1μA - Ultra-low leakage preserves signal integrity and battery life in always-on systems |
| TJ max | +150°C - Enables operation in under-hood automotive environments and high-power industrial enclosures |
Pinout & Package
DO-214AA (SMB) surface-mount package: compact 4.57mm × 3.94mm footprint with matte tin-plated leads, UL 94V-0 molding compound, and cathode band marking for polarity identification. Bidirectional configuration eliminates need for orientation-specific placement.

Applications
| Automotive Power Distribution | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12V/24V power rails in vehicle ECUs from alternator load dump and relay coil flyback. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly across input terminals of power management ICs or microcontrollers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ82CA | Same DO-214AA package, identical VBR (73.8–90.2V), but rated for 600W with slightly higher VC (119V vs. 118V); not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 is not required and cost optimization is prioritized |
| 1.5SMC82CA | Higher 1500W rating, same VBR range, but larger DO-214AB (SMC) package (7.11mm × 6.22mm) | Requires PCB layout change; better suited for high-energy surge zones like main power entry | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space allows larger footprint |
Compared with SMBJ82CA and 1.5SMC82CA, the P6SMB82CH provides AEC-Q101 validation and optimal size-to-power ratio for space-constrained automotive modules, while maintaining identical electrical clamping performance to SMBJ82CA and offering smaller footprint than 1.5SMC82CA.

FAQ
What does the 'CH' suffix indicate in P6SMB82CH?
The 'CH' suffix in P6SMB82CH denotes a bidirectional configuration with symmetrical clamping characteristics in both forward and reverse directions. Unlike unidirectional variants (e.g., P6SMB82H), the P6SMB82CH has no defined anode/cathode polarity and functions identically regardless of voltage polarity applied-making it ideal for protecting AC-coupled or differential signal lines and eliminating orientation concerns during automated assembly.
Is P6SMB82CH qualified for automotive applications?
Yes, P6SMB82CH is AEC-Q101 qualified, meaning it has passed stress tests for high-temperature operating life, temperature cycling, humidity bias HAST, and mechanical shock specific to automotive electronics. This qualification confirms its suitability for under-hood and cabin applications such as body control modules, lighting controllers, and infotainment power supplies where reliability under thermal and vibration stress is critical.
What is the maximum clamping voltage of P6SMB82CH and how is it measured?
The maximum clamping voltage (VC) of P6SMB82CH is 118V, measured at IPPM = 5.3A using the standardized 10/1000μs double-exponential surge waveform. This value represents the peak voltage that appears across the device terminals during worst-case transient conduction and defines the upper voltage limit imposed on protected circuitry-ensuring downstream components rated for ≤120V operation remain within safe operating area.
How does P6SMB82CH compare to P6SMB82AH in terms of electrical parameters?
P6SMB82CH and P6SMB82AH share identical breakdown voltage range (73.8–90.2V), stand-off voltage (66.4V), and clamping voltage (118V), but differ in configuration: P6SMB82CH is bidirectional while P6SMB82AH is unidirectional. The 'AH' variant requires correct polarity placement and offers slightly lower leakage (<1μA) at VWM, whereas the 'CH' version provides polarity-agnostic protection essential for differential or AC-linked circuits.
Can P6SMB82CH be used in parallel for higher surge current handling?
No, P6SMB82CH should not be paralleled for increased current capacity due to mismatch in dynamic impedance and VBR tolerances, which causes uneven current sharing and potential thermal runaway. For higher surge ratings, select a single-device alternative like 1.5SMC82CA (1500W) or verify derating curves in the datasheet for multi-pulse duty cycles rather than parallel placement.
