Product details
Overview
P6SMB100AHM3_A/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 (PPPM) with 10/1000 μs waveform. 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_A/H datasheet, P6SMB100AHM3_A/H pinout, P6SMB100AHM3_A/H application, or P6SMB100AHM3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, MSL Level 1 rating, and 150 °C max junction temperature - all critical for automotive-grade board-level surge protection design.
Technical Context
The P6SMB100AHM3_A/H uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective clamping of transient overvoltages before downstream components are damaged. Its unidirectional configuration provides forward conduction capability with VF = 3.5 V at IF = 50 A, supporting bidirectional surge suppression when paired with complementary devices.
Thermally, it features RθJA = 100 °C/W and RθJL = 20 °C/W, requiring minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated 600 W pulse handling. The device operates across -65 °C to +150 °C junction temperature range and meets JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 85.5 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin. |
| VBR (Breakdown) | 95.0–105 V at IT = 1.0 mA - Voltage at which device enters avalanche breakdown; ensures precise trigger threshold. |
| VC (Clamping) | 137 V at IPPM = 4.4 A - Maximum voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; enables robust protection against IEC 61000-4-5 Level 4 surges. |
| ID (Leakage) | 1.0 μA at VWM - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss. |
| TJ max | +150 °C - Enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures. |
| Package | SMB (DO-214AA) - Low-profile SMT package compatible with automated placement; footprint matches industry-standard layout. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, MSL Level 1 (260 °C peak reflow), 0.106 g unit weight. Cathode indicated by band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground during overvoltage events. |
| Anode (unbanded end) | Reference node | Typically tied to system ground or low-impedance return path; completes clamping loop. |

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), and PPPM (600 W); SMA package (DO-214AC), slightly larger footprint and higher RθJA (140 °C/W). | Lacks AEC-Q101 qualification and halogen-free certification; suitable for commercial-grade designs only. | Select when cost sensitivity outweighs automotive qualification or when existing SMA land pattern is fixed. |
| 1.5SMC100A | Same electrical specs but SMC (DO-214AB) package; 1.5 kW PPPM rating (derated to 600 W at 0.01% duty cycle); higher thermal mass. | Higher power headroom supports longer surge durations; not AEC-Q101 qualified; RoHS-compliant only (not halogen-free). | Choose for industrial systems requiring extended surge endurance beyond standard 10/1000 μs test conditions. |
Compared with SMAJ100A-E3/5B and 1.5SMC100A, the P6SMB100AHM3_A/H uniquely combines AEC-Q101 qualification, halogen-free construction, and SMB footprint - making it the preferred choice for space-constrained, thermally demanding automotive and industrial designs where regulatory compliance and long-term supply continuity are mandatory.

FAQ
What is the clamping voltage of the P6SMB100AHM3_A/H under maximum rated surge current?
The P6SMB100AHM3_A/H has a maximum clamping voltage (VC) of 137 V at 4.4 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuits during transient events. The P6SMB100AHM3_A/H maintains this clamping performance across its specified operating temperature range and duty cycle limits.
Is the P6SMB100AHM3_A/H qualified for automotive applications?
Yes, the P6SMB100AHM3_A/H is AEC-Q101 qualified, as confirmed by the HM3 suffix and documentation in Vishay's P6SMB series datasheet (Document Number: 88370, Revision: 09-Jan-2024). This qualification validates its reliability for use in automotive powertrain, chassis, and body electronics where temperature cycling, humidity, and mechanical shock resistance are required. The P6SMB100AHM3_A/H meets all applicable stress tests including HTGB, TST, and AC-H3TRB.
What does the "HM3" suffix indicate in P6SMB100AHM3_A/H?
The "HM3" suffix in P6SMB100AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering nomenclature, "H" indicates 7" tape-and-reel packaging, "M3" specifies halogen-free and RoHS-compliant materials, and the underscore "_A/H" reflects revision code "A" and packaging format "H". This distinguishes it from commercial-grade E3/M3 variants and non-automotive HE3/HM3 versions without revision coding.
How does the P6SMB100AHM3_A/H compare to bidirectional TVS diodes in the same series?
The P6SMB100AHM3_A/H is unidirectional, meaning it blocks reverse voltage up to 85.5 V and clamps positive transients only - unlike bidirectional variants (e.g., P6SMB100CA) that suppress surges of either polarity. Its forward voltage drop (VF = 3.5 V at 50 A) allows integration into DC power paths where polarity is fixed. The P6SMB100AHM3_A/H is not interchangeable with bidirectional types without circuit redesign due to polarity dependency and different leakage behavior.
What PCB layout guidelines apply to the P6SMB100AHM3_A/H for optimal thermal and electrical performance?
Vishay specifies mounting the P6SMB100AHM3_A/H on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and thermal resistance (RθJA = 100 °C/W). Trace width should minimize inductance between TVS and protected node; ground connections must be low-impedance and short. The P6SMB100AHM3_A/H requires no additional heatsinking under standard derating curves, but ambient temperature rise must be accounted for above TA = 25 °C.
