Product details
Overview
P6SMB100AHM3/H 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 clamping voltage (VC) at 4.4 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P6SMB100AHM3/H datasheet, P6SMB100AHM3/H pinout, P6SMB100AHM3/H application, or P6SMB100AHM3/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, 150 °C max junction temperature, and MSL Level 1 moisture sensitivity rating.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at 85.5 V), but triggers avalanche breakdown when transient voltage exceeds its 95–105 V breakdown range (VBR at 1 mA), clamping downstream circuitry to ≤137 V within nanoseconds. Its low incremental surge resistance ensures minimal voltage overshoot during fast transients.
Designed for automated SMT assembly, the device uses glass-passivated silicon junctions and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101 qualified construction - validated per JESD201 Class 2 whisker testing and JEDEC J-STD-020 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC bias margin. |
| VBR (Breakdown Voltage) | 95.0–105 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 137 V at IPPM = 4.4 A (10/1000 μs) - Actual maximum voltage seen by protected circuit during worst-case surge. |
| PPPM (Peak Pulse Power) | 600 W - Sustains 10/1000 μs transients at 0.01% duty cycle without degradation; enables robust ESD/lightning protection. |
| TJ max | 150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| Package | SMB (DO-214AA) - Standardized 2-pin surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with IPC-7351B land patterns. |
| Polarity | Unidirectional - Cathode marked by band; blocks forward conduction above ~3.5 V (VF = 3.5 V at 50 A), conducts only in reverse avalanche. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; terminals are matte tin-plated copper leads suitable for lead-free reflow soldering per J-STD-020 (260 °C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse surge return path | Connected to system ground or low-side reference; carries full surge current during clamping. |
| Cathode | Avalanche conduction node / Protected line connection | Connected to line being protected (e.g., sensor supply or data line); voltage referenced to anode during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables reliable suppression of IEC 61000-4-5 Level 4 surges (4 kV, 2 Ω source) on 24 V industrial buses without derating. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive powertrain and body electronics per stress test requirements including HTOL, TCT, and ESD HBM ≥ 8 kV. |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and IPC-1752A material declarations; supports green manufacturing and end-of-life recycling. |
| MSL Level 1 (260 °C peak) | Allows unlimited floor life and single-reflow processing without baking; eliminates moisture-related popcorning risk in production. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on downstream ICs - critical for protecting 100 V-rated MOSFETs and precision analog front-ends. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses in vehicle ECUs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A | 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 (IEC 61000-4-5 Level 2); unsuitable for automotive load-dump where 600 W is required. | Select P6SMB100AHM3/H when 600 W rating, AEC-Q101 qualification, or SMB mechanical robustness are mandatory. |
| 1.5SMC100A | Identical electrical specs (VWM, VBR, VC, PPPM), but SMC (DO-214AB) package - 7.11 mm × 6.22 mm, 2× PCB area, higher thermal mass. | Better thermal dissipation in high-repetition-rate environments; less suitable for dense layouts or automated placement with tight pitch. | Choose P6SMB100AHM3/H for space-constrained SMT designs requiring AEC-Q101 and halogen-free compliance in smallest standardized TVS outline. |
Compared with SMAJ100A, P6SMB100AHM3/H delivers 50% higher surge power handling and automotive qualification; versus 1.5SMC100A, it reduces board area by 42% while maintaining full 600 W capability and enabling finer-pitch placement.

FAQ
What is the clamping voltage of P6SMB100AHM3/H at its rated peak pulse current?
The P6SMB100AHM3/H has a maximum clamping voltage (VC) of 137 V when subjected to its specified peak pulse current (IPPM) of 4.4 A under the standard 10/1000 μs waveform. This value is measured at TA = 25 °C with devices mounted on 0.2" x 0.2" copper pads per JEDEC guidelines. The clamping performance remains stable across its -65 °C to +150 °C operating junction temperature range, making P6SMB100AHM3/H suitable for under-hood automotive use.
Is P6SMB100AHM3/H suitable for automotive applications?
Yes, P6SMB100AHM3/H is AEC-Q101 qualified - confirmed by the "HM3" suffix denoting halogen-free, RoHS-compliant, and automotive-grade construction. It passes stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body model (HBM) ESD ≥ 8 kV. The device's 150 °C max junction temperature, MSL Level 1 rating, and JESD201 Class 2 whisker resistance make P6SMB100AHM3/H appropriate for engine control units, body electronics, and ADAS sensor interfaces.
How does the HM3 suffix differ from the M3 or E3 suffix in the P6SMB series?
The HM3 suffix on P6SMB100AHM3/H indicates halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. In contrast, M3 denotes halogen-free and RoHS-compliant but commercial-grade (non-automotive), while E3 is RoHS-compliant commercial grade without halogen-free assurance. Only HM3 and HE3 variants carry AEC-Q101 validation; P6SMB100AHM3/H specifically meets automotive reliability requirements with enhanced process controls and lot traceability not present in M3 or E3 versions.
What is the thermal resistance of P6SMB100AHM3/H, and how does it affect layout design?
P6SMB100AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" x 0.2" (5.0 mm x 5.0 mm) copper pads per terminal. Its junction-to-lead resistance (RθJL) is 20 °C/W. To maintain safe operation under repetitive surges, PCB layout must provide adequate copper area and avoid thermal bottlenecks - undersized traces or insufficient ground planes will raise junction temperature beyond the 150 °C limit and degrade P6SMB100AHM3/H lifetime.
Can P6SMB100AHM3/H be used in bidirectional configurations?
No, P6SMB100AHM3/H is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). Its cathode is marked with a band, and it conducts only in reverse avalanche - forward conduction occurs above ~3.5 V (VF = 3.5 V at 50 A), which is not intended for protection. For bidirectional protection at the same voltage level, the correct variant is P6SMB100CHM3/H ("C" = complementary, bidirectional), which exhibits symmetrical clamping in both polarities and no polarity marking.
