Product details
Overview
P6SMB100CAHM3_B/I from Vishay General Semiconductor is a bidirectional 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 (PPPM) with 10/1000 μs waveform. It protects signal lines and power rails in automotive sensor units, industrial I/O interfaces, and telecom front-end circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB100CAHM3_B/I datasheet, P6SMB100CAHM3_B/I pinout, P6SMB100CAHM3_B/I application, or P6SMB100CAHM3_B/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient overvoltage events exceeding its 100 V standoff threshold, it avalanches symmetrically in both directions to clamp the line at ≤137 V while diverting up to 4.4 A (10/1000 μs). Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 μA at VWM).
Designed for high-reliability environments, P6SMB100CAHM3_B/I features halogen-free RoHS compliance, JESD201 Class 2 whisker resistance, and thermal resistance of 100 °C/W (junction-to-ambient) when mounted per recommended pad layout. It supports repetitive surge duty cycles up to 0.01 % at TA = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 100 V - Maximum continuous reverse voltage before clamping initiates; defines operating margin below breakdown. |
| VBR (Breakdown) | 105 V min / 116 V max at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on under transient stress. |
| VC (Clamping) | 137 V at IPPM = 4.4 A - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge; determines system overvoltage margin. |
| PPPM | 600 W - Surge energy handling capacity with standard 10/1000 μs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| Package | SMB (DO-214AA) - Surface-mount outline with 0.220" × 0.130" footprint; compatible with standard reflow profiles and J-STD-020 MSL Level 1. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
| Leakage (ID) | ≤1.0 μA at 100 V - Minimal DC loading on signal/power lines during normal operation; preserves low-power system integrity. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Case dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated for solderability per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | One terminal of symmetrical PN junction; accepts surge current regardless of polarity relative to cathode. |
| Cathode | Transient current exit (bidirectional) | Second terminal of symmetrical PN junction; completes low-impedance path during clamping in either direction. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints. |
| 600 W peak pulse power | Supports IEC 61000-4-5 surge immunity up to 4 kV (line-earth) in properly designed PCB layouts. |
| AEC-Q101 qualified (HM3_B suffix) | Validated for automotive powertrain, body control, and ADAS sensor modules requiring extended lifetime and thermal stability. |
| MSL Level 1, 260 °C peak reflow | Permits use in standard lead-free reflow processes without baking or special handling. |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for EU, China RoHS, and JEITA standards in industrial and consumer end equipment. |
Applications
| Automotive Sensor Interface | Industrial Digital I/O Protection |
|---|---|
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine control modules from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Shunt TVS diode placed between signal line and ground, responding within <1 ns to clamp transients above 100 V.

Use Scenario: Safeguarding PLC digital input channels connected to 24 V DC field wiring exposed to relay coil flyback and EMI coupling. IC Role / Device Role / Timing Role: Bidirectional voltage clamp across input terminals, limiting voltage excursion to ≤137 V during 600 W surges. Use Value: Eliminates need for separate unidirectional devices per line; reduces BOM count and PCB area in DIN-rail mounted controllers. |
| Telecom Line Interface | Consumer Power Supply Input |
Use Scenario: Secondary-side transient suppression on Ethernet PHY power rails (3.3 V, 5 V) and MDI differential pairs in PoE-powered switches. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed adjacent to connector, clamping ESD (IEC 61000-4-2) and lightning-induced surges. Use Value: Maintains signal integrity with <10 pF junction capacitance while meeting GR-1089-CORE Level 3 surge requirements. |
Use Scenario: Input-stage surge protection for USB-C PD adapters and AC-DC wall adapters handling 100–240 VAC inputs. IC Role / Device Role / Timing Role: Primary clamping element across bridge rectifier output or bulk capacitor, absorbing 10/1000 μs line surges. Use Value: Enables compact design with 600 W rating in SMB package-replaces larger DO-15 or SMA devices without sacrificing robustness. |
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 (100 V), lower PPPM (400 W), SMA package (larger footprint, higher RθJA = 140 °C/W) | Limited to lower-energy surges; less suitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select when cost sensitivity outweighs surge margin and board space permits larger SMA outline. |
| 1.5SMC100CA | Same VWM and PPPM (600 W), but SMC package (7.11 mm × 6.22 mm); higher thermal mass but incompatible with SMB land pattern. | Preferred for high-temperature ambient designs (>105 °C) due to lower RθJA (~50 °C/W), but requires PCB redesign. | Choose only if thermal derating dominates layout constraints and AEC-Q101 is not required. |
Compared with SMAJ100CA and 1.5SMC100CA, P6SMB100CAHM3_B/I delivers identical 100 V bidirectional clamping with full 600 W surge rating in the smallest qualified SMB footprint, plus AEC-Q101 validation and MSL Level 1 process compatibility-making it optimal for space-constrained automotive and industrial SMT production.

FAQ
What is the clamping voltage of P6SMB100CAHM3_B/I at its rated peak pulse current?
The P6SMB100CAHM3_B/I has a maximum clamping voltage (VC) of 137 V when subjected to its specified peak pulse current (IPPM) of 4.4 A using the 10/1000 μs waveform. This value is measured per Figure 1 in Vishay Document 88370 and defines the upper voltage limit imposed on protected circuitry during surge events.
Is P6SMB100CAHM3_B/I suitable for automotive applications?
Yes, P6SMB100CAHM3_B/I is AEC-Q101 qualified (indicated by the HM3_B suffix), meaning it has passed stress tests for temperature cycling, high-temperature reverse bias, and ESD required for automotive electronic modules. It is commonly used in engine control units, body electronics, and ADAS sensor interfaces.
What does the "CA" suffix mean in P6SMB100CAHM3_B/I?
The "CA" suffix in P6SMB100CAHM3_B/I denotes a bidirectional configuration: the device provides symmetrical transient suppression in both forward and reverse directions, making it ideal for AC signal lines, differential buses, or floating power domains where polarity is undefined or alternating.
How does the SMB package of P6SMB100CAHM3_B/I compare to SMA or SMC alternatives?
The SMB (DO-214AA) package of P6SMB100CAHM3_B/I measures 4.57 mm × 3.94 mm, offering ~30 % smaller footprint than SMA and ~50 % smaller than SMC. While thermal resistance is higher (RθJA = 100 °C/W vs. ~50 °C/W for SMC), its MSL Level 1 rating and compatibility with standard reflow make it preferred for high-density, high-volume SMT assembly.
What is the maximum leakage current of P6SMB100CAHM3_B/I at its standoff voltage?
At its 100 V standoff voltage (VWM), the P6SMB100CAHM3_B/I exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C. This low leakage ensures minimal power loss and signal distortion in battery-powered or precision analog circuits where standby current is critical.
