Product details
Overview
P6SMB100AHM3_B/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 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 surges in automotive and industrial power supplies.
For engineers reviewing the P6SMB100AHM3_B/I datasheet, P6SMB100AHM3_B/I pinout, P6SMB100AHM3_B/I application, or P6SMB100AHM3_B/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature limit (150 °C), and bidirectional compatibility context for system-level surge protection design.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1 μA leakage at 85.5 V), then rapidly avalanches below 137 V to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance.
Designed for automated SMT assembly, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C), features matte tin-plated leads compliant with JESD 22-B102, and supports repetitive 0.01% duty-cycle pulses. The cathode band identifies polarity; no marking on bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working range. |
| VBR (Breakdown Voltage) | 95.0–105 V at 1 mA - Voltage at which avalanche conduction initiates; ensures precise overvoltage threshold activation. |
| VC (Clamping Voltage) | 137 V at IPPM = 4.4 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines stress margin for downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Maximum transient energy dissipation capability with standard 10/1000 μs waveform; enables robust surge handling per IEC 61000-4-5. |
| TJ max. | 150 °C - Maximum junction temperature rating; sets thermal derating boundary for sustained operation and surge recovery. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs PCB layout cooling requirements. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC-Q101 Rev D. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, with matte tin-plated leads. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H). Mounting pad layout requires 5.0 mm × 5.0 mm copper area per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode-side connection in unidirectional configuration | Reverse-biased terminal accepting transient energy; connects to protected line (e.g., VBUS or signal); clamps when voltage exceeds VBR. |
| Anode | Reference/ground return path | Connects to system ground or low-impedance return; completes clamping current path during surge events; must maintain low-inductance layout. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity without external series impedance in many 12–48 V systems. |
| Low clamping ratio (VC/VBR ≈ 1.34) | Minimizes overvoltage overshoot during fast transients, preserving margin for 100 V-rated MOSFETs and gate drivers. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive powertrain and body electronics applications requiring extended temperature cycling and long-term reliability. |
| MSL Level 1 moisture sensitivity | Enables direct placement into high-volume SMT lines without baking; compatible with standard 260 °C lead-free reflow profiles. |
| Glass passivated junction | Ensures stable VBR tolerance (±5%), low leakage drift over time, and immunity to humidity-induced parameter shift. |
Applications
| Automotive Power Supply Protection | Industrial Sensor Signal Line Guarding |

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-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 automotive load-dump where 600 W margin is required. | Select when board space is constrained and surge threat level is ≤ IEC 61000-4-5 Level 3. |
| 1.5SMC100AHE3_A/H | Same VWM/VC/PPPM specs, but SMC (DO-214AB) package: larger footprint (7.11 mm × 6.22 mm), lower RθJA (60 °C/W), higher IFSM (200 A). | Better thermal performance and surge endurance; preferred for high-reliability industrial power supplies with frequent transients. | Choose when thermal management is critical or when legacy SMC footprints exist in BOM. |
Compared with P6SMB100AHM3_B/I, SMAJ100A-E3/5B trades power handling for compactness, while 1.5SMC100AHE3_A/H offers superior thermal robustness at the cost of PCB area-making P6SMB100AHM3_B/I the optimal balance of AEC-Q101 compliance, 600 W capability, and SMB footprint for automotive and industrial edge nodes.

FAQ
What is the clamping voltage of the P6SMB100AHM3_B/I under maximum rated surge conditions?
The P6SMB100AHM3_B/I has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current (IPPM) of 4.4 A using the standard 10/1000 μs waveform. This value is measured at TA = 25 °C with devices mounted on 0.2" × 0.2" copper pads per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB100AHM3_B/I maintains this clamping performance across its operational junction temperature range.
Is the P6SMB100AHM3_B/I qualified for automotive applications?
Yes, the P6SMB100AHM3_B/I is AEC-Q101 qualified, as confirmed by the HM3 suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024, Doc. #88370). It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D, making it suitable for automotive powertrain, body electronics, and ADAS subsystems. The P6SMB100AHM3_B/I is explicitly listed in the "AEC-Q101 qualified" ordering table with _B revision code.
What does the "_B/I" suffix in P6SMB100AHM3_B/I indicate?
The "_B" denotes AEC-Q101 qualification for the P6SMB100AHM3_B/I within the 6.8 V to 220 V VWM range, while "/I" specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. The "HM3" portion confirms halogen-free, RoHS-compliant construction with matte tin plating. This full suffix ensures traceability to automotive-grade manufacturing, material compliance, and logistics configuration-critical for Tier 1 automotive procurement. The P6SMB100AHM3_B/I meets JESD 201 Class 2 whisker resistance requirements.
How does the thermal performance of P6SMB100AHM3_B/I compare to similar SMB-packaged TVS diodes?
The P6SMB100AHM3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads-matching industry-standard SMB thermal benchmarks. Its RθJL (junction-to-lead) is 20 °C/W, supporting efficient heat transfer to PCB copper. Unlike non-qualified variants, the HM3 construction maintains this thermal profile across extended temperature cycling, ensuring stable clamping voltage and leakage current over lifetime. The P6SMB100AHM3_B/I's thermal specs are validated per JEDEC test conditions and published in the official Vishay datasheet.
Can the P6SMB100AHM3_B/I be used in bidirectional configurations?
No, the P6SMB100AHM3_B/I is a unidirectional TVS diode, indicated by the "A" suffix (not "CA") and presence of a cathode band. Bidirectional variants in the same series use the "CA" suffix (e.g., P6SMB100CA) and lack polarity marking. Using the P6SMB100AHM3_B/I in AC or floating signal paths would result in forward conduction during negative half-cycles, causing failure. For bidirectional protection at 100 V, select P6SMB100CAHM3_B/I instead-the P6SMB100AHM3_B/I is strictly for DC-line or referenced signal clamping.
