Product details
Overview
P6SMB100AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 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 (PPPM) with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning-induced surges in industrial and automotive electronics.
For engineers reviewing the P6SMB100AHM3/I datasheet, P6SMB100AHM3/I pinout, P6SMB100AHM3/I application, or P6SMB100AHM3/I equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, unidirectional polarity marking, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
The P6SMB100AHM3/I operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to limit transient overvoltage before sensitive circuitry is damaged. Its breakdown voltage (VBR) is specified at 95.0–105 V with 1 mA test current, ensuring precise triggering near system rail limits.
Designed for surface-mount automated assembly on PCBs with 0.2" × 0.2" copper pads per terminal, it meets J-STD-020 MSL Level 1 (peak reflow ≤260 °C) and JESD201 Class 2 whisker resistance. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification for automotive-grade reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/5B | Same VWM (85.5 V), VC = 137 V, but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy transients; less suitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select when board space is constrained and surge energy is ≤400 W; verify thermal derating at elevated ambient. |
| 1.5SMC100A | Same electrical specs (VWM = 85.5 V, VC = 137 V, PPPM = 600 W), but SMC (DO-214AB) package - larger footprint (0.205" × 0.245") and higher mounting pad area. | Better thermal performance (RθJA ≈ 60 °C/W) but incompatible with SMB-reflow profiles and layout. | Choose when thermal management is critical and PCB real estate allows larger SMC footprint; not drop-in compatible. |
Compared with SMAJ100A-E3/5B and 1.5SMC100A, the P6SMB100AHM3/I delivers identical clamping performance in a compact, automotive-qualified SMB package with optimized reflow compatibility and halogen-free compliance - making it the preferred choice for space-constrained, high-reliability industrial and automotive designs.

FAQ
What is the maximum clamping voltage of the P6SMB100AHM3/I under a 10/1000 μs surge?
The P6SMB100AHM3/I has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 4.4 A using the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the highest voltage the protected circuit will experience during such a transient event. The P6SMB100AHM3/I maintains this clamping performance across its operational temperature range and after repeated surge exposure.
Is the P6SMB100AHM3/I suitable for automotive applications?
Yes, the P6SMB100AHM3/I is AEC-Q101 qualified, as confirmed by the HM3 suffix and Vishay documentation. It undergoes rigorous stress testing including temperature cycling, high-temperature operating life, and mechanical shock per AEC-Q101 requirements. The P6SMB100AHM3/I is explicitly recommended for automotive body control modules, sensor interfaces, and infotainment power rails where reliability under vibration and thermal extremes is critical.
What does the "HM3" suffix indicate in P6SMB100AHM3/I?
The "HM3" suffix in P6SMB100AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. "H" specifies the halogen-free material set, "M3" indicates RoHS compliance and JESD201 Class 2 whisker resistance, and the "I" denotes 13-inch tape-and-reel packaging (3200 units per reel). This suffix differentiates it from commercial-grade E3/M3 variants and confirms suitability for automotive and environmentally regulated industrial designs.
How does the P6SMB100AHM3/I compare to bidirectional TVS diodes like P6SMB100CA?
The P6SMB100AHM3/I is unidirectional and features a cathode band for polarity identification, allowing it to conduct only during positive overvoltage events - ideal for DC power rails and single-polarity signal lines. In contrast, P6SMB100CA is bidirectional with no polarity marking and clamps both positive and negative transients, making it suitable for AC lines or differential buses. The P6SMB100AHM3/I offers tighter leakage control in DC applications and avoids false triggering on negative excursions.
What is the thermal resistance and maximum power dissipation of the P6SMB100AHM3/I?
The P6SMB100AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads. Its steady-state power dissipation (PD) is rated at 5.0 W at TA = 50 °C. This means under continuous DC stress, the device can safely dissipate up to 5 W with appropriate board-level thermal design; the P6SMB100AHM3/I relies on its 600 W peak pulse rating for transient handling, not sustained power.
