Product details
Overview
P6SMB100CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 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 capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the P6SMB100CAHM3/I datasheet, P6SMB100CAHM3/I pinout, P6SMB100CAHM3/I application, or P6SMB100CAHM3/I equivalent, this device is selected for robust ESD and surge protection where bidirectional clamping, AEC-Q101 qualification, halogen-free RoHS compliance, and SMB (DO-214AA) package compatibility are required.
Technical Context
The P6SMB100CAHM3/I operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while its thermal resistance (RθJA = 100 °C/W) supports operation up to +150 °C junction temperature under defined PCB pad conditions.
It delivers repeatable 600 W surge handling per IEC 61000-4-5 (10/1000 μs) at 0.01% duty cycle, with fast response time (<1.0 ns) and low incremental surge resistance - enabling effective suppression of inductive switching spikes and lightning-induced surges on unprotected lines.
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 - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 137 V at IPPM = 4.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Same VWM (85.5 V), VC (137 V), and SMB package; rated for 600 W but uses different internal chip design and not AEC-Q101 qualified. | Lacks automotive qualification; suitable for commercial/industrial use only. | Select SMBJ100CA if AEC-Q101 is not required and cost optimization is prioritized. |
| 1.5KE100CA | Through-hole DO-201 package; same 100 V bidirectional rating and 137 V clamping, but higher RθJA (75 °C/W) and larger footprint. | Requires PCB through-hole assembly; less suitable for high-density automotive PCBs. | Choose 1.5KE100CA only when legacy through-hole design or higher surge repetition rate is needed. |
Compared with SMBJ100CA and 1.5KE100CA, the P6SMB100CAHM3/I uniquely combines AEC-Q101 qualification, halogen-free compliance, and surface-mount SMB packaging - making it the preferred choice for new automotive electronics designs requiring zero-layout rework and full regulatory traceability.

FAQ
What does the "HM3" suffix indicate in P6SMB100CAHM3/I?
The "HM3" suffix in P6SMB100CAHM3/I denotes halogen-free, RoHS-compliant construction with full AEC-Q101 qualification. This means the device has passed rigorous automotive reliability testing including temperature cycling, highly accelerated life testing (HALT), and surge endurance - verified per JESD22-A108 and JESD22-A110. The "I" indicates 13-inch tape-and-reel packaging (3200 units per reel), supporting automated SMT assembly.
Is P6SMB100CAHM3/I unidirectional or bidirectional?
P6SMB100CAHM3/I is a bidirectional TVS diode, confirmed by the "CA" suffix and absence of polarity marking on the SMB (DO-214AA) package. Its electrical characteristics - including symmetrical VBR (95.0–105 V), VWM (85.5 V), and VC (137 V) - apply identically in both directions. This allows placement across floating or AC-coupled lines without orientation constraints, unlike unidirectional variants such as P6SMB100AHM3/I.
What is the maximum clamping voltage of P6SMB100CAHM3/I and under what test condition?
The maximum clamping voltage of P6SMB100CAHM3/I is 137 V, measured at a peak pulse current (IPPM) of 4.4 A using a 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range (−65 °C to +150 °C) when mounted on the specified 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal - critical for achieving rated surge performance.
Does P6SMB100CAHM3/I require special PCB layout considerations?
Yes - P6SMB100CAHM3/I requires minimum 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per terminal to achieve its rated 600 W peak pulse power and thermal performance. Smaller pads increase thermal resistance and reduce surge capability. The SMB (DO-214AA) footprint must follow Vishay's recommended pad layout (Document 88370, page 5), and no soldermask should cover the pad edges to maximize heat dissipation and mechanical reliability during reflow.
How does P6SMB100CAHM3/I compare to P6SMB100A in terms of automotive suitability?
P6SMB100CAHM3/I is AEC-Q101 qualified and halogen-free, whereas P6SMB100A (without HM3 suffix) is commercial-grade only. The HM3 variant undergoes additional stress testing including 1000-hour high-temperature reverse bias (HTRB) and temperature cycling (−40 °C to +125 °C, 1000 cycles), making P6SMB100CAHM3/I suitable for under-hood automotive applications. P6SMB100A lacks this validation and is restricted to non-automotive use cases.
