Product details
Overview
P6SMB100CAHM3/H 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 100 V standoff voltage (VWM), 137 V maximum clamping voltage (VC) at 4.4 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P6SMB100CAHM3/H datasheet, P6SMB100CAHM3/H pinout, P6SMB100CAHM3/H application, or P6SMB100CAHM3/H equivalent, this device serves as a halogen-free, AEC-Q101-qualified transient protector for bidirectional signal lines where low clamping voltage, fast response (<1 ns), and robust surge immunity are required in space-constrained SMB packages.
Technical Context
The P6SMB100CAHM3/H operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 μA at 85.5 V), while the 100 °C/W junction-to-ambient thermal resistance supports operation up to +150 °C junction temperature under defined PCB pad conditions.
It delivers 600 W peak pulse power per the 10/1000 μs standard waveform at TA = 25 °C, with derating above 25 °C per Figure 2. The device meets JESD201 Class 2 whisker resistance and MSL Level 1 reflow compatibility (260 °C peak), making it suitable for automated SMT assembly in high-reliability automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 95.0–105 V at 1 mA - Confirmed voltage range where device enters avalanche breakdown; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 137 V at IPPM = 4.4 A - Peak voltage seen across protected circuit during 10/1000 μs surge; critical for IC-level overvoltage margining. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capacity per JEDEC standard; enables protection against IEC 61000-4-5 Level 4 surges. |
| ID (Reverse Leakage) | <1 μA at 85.5 V - Minimal standby current draw; preserves signal integrity and battery life in always-on circuits. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and high-ambient industrial settings. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100CA | Same VWM (85.5 V) and VC (137 V), but lower PPPM (400 W); SMB package identical; not AEC-Q101 qualified. | Acceptable for commercial-grade industrial controls but unsuitable for automotive under-hood use. | Select SMAJ100CA only when AEC-Q101 qualification and 600 W surge margin are not required. |
| 1.5SMC100CA | Higher power rating (1500 W), larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); same VWM/VC specs; AEC-Q101 available in HM3 variant. | Requires PCB layout change; better suited for high-energy AC mains or DC bus protection where space allows. | Choose 1.5SMC100CA when surge threat level exceeds 600 W or when thermal dissipation demands larger case size. |
Compared with SMAJ100CA and 1.5SMC100CA, the P6SMB100CAHM3/H uniquely balances AEC-Q101 qualification, 600 W surge capability, and compact SMB footprint - making it optimal for automotive and space-constrained industrial designs requiring certified reliability without board redesign.

FAQ
What does the "CA" suffix indicate in P6SMB100CAHM3/H?
The "CA" suffix in P6SMB100CAHM3/H denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB100AHM3/H), it has no cathode band marking and functions identically in either orientation - essential for protecting AC-coupled or differential signal lines without polarity constraints.
Is P6SMB100CAHM3/H suitable for automotive applications?
Yes, P6SMB100CAHM3/H is AEC-Q101 qualified (indicated by the "HM3" suffix and "_B" revision code per ordering table), making it approved for automotive use including engine control units, body electronics, and ADAS sensor interfaces. Its halogen-free, RoHS-compliant construction and MSL Level 1 reflow rating further support automotive manufacturing requirements.
What is the maximum clamping voltage of P6SMB100CAHM3/H under surge conditions?
The maximum clamping voltage (VC) of P6SMB100CAHM3/H is 137 V at a peak pulse current (IPPM) of 4.4 A, measured using the standardized 10/1000 μs waveform. This value represents the highest voltage that will appear across protected circuitry during a worst-case transient event - a key parameter for ensuring downstream ICs remain within absolute maximum ratings.
How does the thermal resistance of P6SMB100CAHM3/H affect its power handling?
P6SMB100CAHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. This means each watt of sustained power dissipation raises the junction temperature by ~100 °C above ambient - limiting continuous power (PD) to 5.0 W at TA = 50 °C. For transient events, the 600 W rating applies only for short durations (≤50 ms), leveraging thermal mass rather than steady-state dissipation.
Can P6SMB100CAHM3/H replace P6SMB100A in a design?
No - P6SMB100CAHM3/H is bidirectional, while P6SMB100A is unidirectional and features a cathode band marking. Substituting them requires verifying circuit topology: P6SMB100A conducts only in reverse bias, whereas P6SMB100CAHM3/H clamps in both directions. Using P6SMB100CAHM3/H in place of P6SMB100A may cause unintended conduction in DC-biased lines, risking malfunction or damage.
