Overview
P6SMB82CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 70.1 V standoff voltage (VWM), 77.9–86.1 V breakdown voltage (VBR) at 1 mA test current, and 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current (IPPM), with 600 W peak pulse power capability under 10/1000 μs waveform.
For engineers reviewing the P6SMB82CAHM3/I datasheet, P6SMB82CAHM3/I pinout, P6SMB82CAHM3/I application, or P6SMB82CAHM3/I equivalent, key selection criteria include bidirectional clamping performance, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, and suitability for automotive sensor line protection where low-leakage (<1 μA at VWM) and fast response time are critical.
Technical Context
This device operates as a voltage-clamping protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. It exhibits a temperature coefficient of VBR at +0.105 %/°C and maintains stable clamping up to 150 °C junction temperature.
Designed for transient suppression per IEC 61000-4-2/4-4/4-5, it delivers 600 W peak pulse power with 0.01 % duty cycle and meets J-STD-020 MSL Level 1 moisture sensitivity with 260 °C reflow peak.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ82CA | Same VWM (70.1 V), identical SMB package, but rated for 600 W with 8.3 ms surge rating instead of 10/1000 μs; slightly higher VC (115 V) | Optimized for longer-duration surges (e.g., AC line faults); less ideal for fast ESD pulses | Select SMBJ82CA only when primary threat is sustained overvoltage rather than nanosecond-scale transients |
| 1.5KE82CA | Through-hole DO-201 package, same VWM/VC specs, but higher thermal mass and 1.5 kW rating; not surface-mount compatible | Requires PCB redesign; suited for prototyping or legacy through-hole systems where rework tolerance is prioritized | Choose 1.5KE82CA only if board space permits axial leaded mounting and manual assembly is acceptable |
Compared with SMBJ82CA and 1.5KE82CA, P6SMB82CAHM3/I provides optimal balance of SMT manufacturability, AEC-Q101 qualification, and precise 10/1000 μs transient response-making it the preferred choice for volume automotive and industrial PCB designs requiring zero-layout change upgrades.

FAQ
What does the 'CA' suffix indicate in P6SMB82CAHM3/I?
The 'CA' suffix in P6SMB82CAHM3/I denotes a bidirectional configuration, meaning the device provides symmetrical clamping for both positive and negative voltage transients. This eliminates polarity concerns during placement and enables use on AC-coupled or differential signal lines without orientation checks-unlike unidirectional variants (e.g., P6SMB82A) which require cathode alignment.
Is P6SMB82CAHM3/I suitable for automotive applications?
Yes, P6SMB82CAHM3/I is AEC-Q101 qualified, as confirmed by its HM3 suffix (halogen-free, RoHS-compliant, and automotive-grade). It supports operating junction temperatures from –65 °C to +150 °C and passes stress tests including temperature cycling, highly accelerated life testing, and ESD robustness-making it appropriate for engine bay, ADAS sensor, and infotainment system protection.
How does the SMB package of P6SMB82CAHM3/I compare to SMA or SMC in layout design?
The SMB (DO-214AA) package of P6SMB82CAHM3/I measures 4.06 mm × 5.59 mm with 2.20 mm height-smaller than SMC (DO-214AB) but larger than SMA (DO-214AC). Its pad layout requires 5.0 mm × 5.0 mm copper areas per terminal for thermal derating compliance, offering better power dissipation than SMA while maintaining compatibility with standard pick-and-place equipment used for mid-density SMT assemblies.
What is the maximum clamping voltage of P6SMB82CAHM3/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB82CAHM3/I is 113 V at 5.3 A peak pulse current (IPPM), measured under the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is guaranteed across the full operating temperature range (–65 °C to +150 °C).
Does P6SMB82CAHM3/I require derating at elevated ambient temperatures?
Yes, P6SMB82CAHM3/I must be derated above TA = 25 °C per Figure 2 in the datasheet: its peak pulse power capability decreases linearly to ~50 % at 100 °C ambient. For continuous operation, its 5.0 W power dissipation rating applies only at TA = 50 °C on infinite heatsink; real-world PCB layouts with limited copper area require additional thermal modeling to ensure junction temperature remains below 150 °C.
