Product details
Overview
P6SMB100CAHM3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the 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 sensitive signal lines and power rails in automotive, industrial, and telecom systems against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the P6SMB100CAHM3_B/H datasheet, P6SMB100CAHM3_B/H pinout, P6SMB100CAHM3_B/H application, or P6SMB100CAHM3_B/H equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown characteristics in both directions due to its bidirectional construction. It exhibits a typical breakdown voltage (VBR) of 105 V at 1 mA test current, with ±5% tolerance (95–105 V), and achieves full clamping response within <1 ns.
Thermally, it features a junction-to-ambient thermal resistance (RθJA) of 100 °C/W and a junction-to-lead resistance (RθJL) of 20 °C/W, enabling reliable operation up to TJ = +150 °C. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and long-term reliability under repetitive surge stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 100 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 95–105 V at IT = 1 mA - Confirmed symmetric breakdown threshold in both directions; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 137 V at IPPM = 4.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines residual stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability per IEC 61000-4-5 waveform; enables robust protection against lightning-induced surges. |
| ID (Reverse Leakage) | <1.0 μA at VWM - Minimal standby current draw; critical for low-power sensor interfaces and battery-backed circuits. |

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 (100 V), VC = 149 V at 4.0 A; lower PPPM (600 W same), but higher RθJA (120 °C/W); non-AEC-Q101. | Lacks automotive qualification; suitable for commercial/industrial use only where AEC compliance is not mandated. | Select when cost sensitivity outweighs automotive qualification needs and thermal margin allows higher RθJA. |
| 1.5SMC100CA | Same VWM/VC specs, but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); higher IPPM (4.7 A); identical AEC-Q101 option available (HM3 suffix). | Requires larger PCB footprint and different pad layout; better thermal dissipation for sustained surge duty cycles. | Choose when board space permits and higher thermal mass improves reliability in high-repetition surge environments. |

FAQ
What does the "CA" suffix indicate in P6SMB100CAHM3_B/H?
The "CA" suffix denotes a bidirectional configuration - meaning P6SMB100CAHM3_B/H provides symmetrical clamping in both polarities, with no cathode marking and identical VBR and VC characteristics regardless of voltage polarity. This makes it ideal for protecting AC-coupled lines, differential buses, or any application where transient direction is unpredictable.
Is P6SMB100CAHM3_B/H suitable for automotive applications?
Yes - P6SMB100CAHM3_B/H carries the HM3 suffix, confirming halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. It has passed rigorous automotive stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD per ISO 10605, making it approved for use in engine control, body electronics, and ADAS subsystems.
What is the maximum clamping voltage of P6SMB100CAHM3_B/H under surge conditions?
The maximum clamping voltage (VC) of P6SMB100CAHM3_B/H is 137 V, measured at a peak pulse current (IPPM) of 4.4 A using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage imposed on the protected circuit during worst-case surge events.
