Product details
Overview
P6SMB100CAHM3_A/H 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 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 signal lines and power rails in automotive sensor interfaces, industrial I/O modules, and telecom surge-prone circuits.
For engineers reviewing the P6SMB100CAHM3_A/H datasheet, P6SMB100CAHM3_A/H pinout, P6SMB100CAHM3_A/H application, or P6SMB100CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, and verified 137 V clamping performance under standardized surge conditions.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both polarities, enabling robust protection of AC-coupled or floating signal paths without polarity sensitivity. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), critical for safeguarding high-speed analog and digital inputs.
The P6SMB100CAHM3_A/H delivers 600 W peak pulse power handling per JEDEC-standard 10/1000 μs waveform, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, supporting reliable operation up to TJ = +150 °C when mounted on 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 95.0–105 V at 1.0 mA test current - Confirmed symmetric conduction threshold in both directions. |
| VC (Clamping Voltage) | 137 V at IPPM = 4.4 A - Measured peak voltage across device during 10/1000 μs surge; determines protected circuit's maximum stress level. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized transient waveform; enables single-event surge survival. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports under-hood automotive and industrial ambient environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102. No polarity marking - bidirectional configuration confirmed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Both terminals function identically; no cathode band marking required for bidirectional operation. |
Key Features
| Feature | Design Value |

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 (85.5 V) and VC (137 V), but lower PPPM (400 W); SMA package (DO-214AC), larger footprint than SMB. | Limited to lower-energy surge environments; not AEC-Q101 qualified. | Select when cost sensitivity outweighs automotive qualification or higher-power surge margin. |
| SMCJ100CA | Higher PPPM (1500 W), same VWM/VC specs; SMC package (DO-214AB), 2.5× larger footprint and higher thermal mass. | Suitable for high-reliability industrial power supplies and motor drives requiring >1 kV surge immunity. | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space permits larger package. |
Compared with SMAJ100CA and SMCJ100CA, the P6SMB100CAHM3_A/H delivers optimal balance of AEC-Q101 qualification, compact SMB footprint, and full 600 W surge capability-making it the preferred choice for space-constrained automotive and industrial edge nodes where reliability and size are co-prioritized.

FAQ
What does the "CA" suffix indicate in P6SMB100CAHM3_A/H?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB100CAHM3_A/H provides symmetrical transient voltage suppression in both polarities-ideal for protecting AC-coupled signals, differential buses, or floating reference points without polarity concerns. This differs from unidirectional variants (e.g., P6SMB100AHM3_A/H) that require correct anode/cathode orientation.
Is P6SMB100CAHM3_A/H qualified for automotive use?
Yes, the HM3 suffix confirms P6SMB100CAHM3_A/H is AEC-Q101 qualified, having passed rigorous stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JESD22-A114. It is approved for under-hood and cabin applications such as engine control sensors, ADAS camera modules, and body control units.
What is the maximum clamping voltage of P6SMB100CAHM3_A/H under surge conditions?
The P6SMB100CAHM3_A/H has a maximum clamping voltage (VC) of 137 V at 4.4 A peak pulse current (IPPM), measured using the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is validated across the full operating temperature range.
How does the SMB (DO-214AA) package of P6SMB100CAHM3_A/H compare to SMA or SMC packages?
The SMB package of P6SMB100CAHM3_A/H offers a 3.94 mm × 2.20 mm footprint-smaller than SMA (DO-214AC) and significantly smaller than SMC (DO-214AB)-enabling high-density PCB layouts. It maintains 600 W surge capability while supporting automated placement and MSL Level 1 reflow, unlike larger alternatives that trade size for higher power ratings.
Does P6SMB100CAHM3_A/H require external polarity marking on the PCB?
No, P6SMB100CAHM3_A/H does not require polarity marking because it is a bidirectional TVS diode with identical electrical behavior in both directions. The SMB package has no cathode band or other polarity indicator-simplifying layout, reducing assembly errors, and enabling direct replacement of unidirectional parts in symmetric protection schemes.
