Product details
Overview
SMB8J10CAHM3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on signal and power lines. It features a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 10 A peak pulse current, and 800 W peak pulse power rating with 10/1000 μs waveform. It is AEC-Q101 qualified and halogen-free, targeting automotive sensor interface and power rail protection.
For engineers reviewing the SMB8J10CAHM3_A/H datasheet, SMB8J10CAHM3_A/H pinout, SMB8J10CAHM3_A/H application, or SMB8J10CAHM3_A/H equivalent, key selection criteria include bidirectional clamping performance at 10 V VWM, AEC-Q101 qualification status, SMB package thermal resistance (RθJL = 20 °C/W), and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within <1 ps to transients exceeding its breakdown threshold (VBR min = 11.1 V, max = 12.3 V at 1 mA). Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and robust surge handling under repetitive stress.
The device is rated for 150 °C maximum junction temperature and exhibits low incremental surge resistance, enabling effective energy diversion during 8/20 μs or 10/1000 μs surges. Its bidirectional symmetry supports AC-coupled lines and differential interfaces without polarity constraints.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB8J10CAHE3_A/H | Same electrical specs; RoHS-compliant but not halogen-free; no AEC-Q101 qualification | Suitable for commercial/industrial use only; not approved for automotive production | Select when halogen-free or automotive qualification is not required and cost optimization is prioritized |
| SMAJ10CA | Lower PPPM (400 W), larger SMA package (DO-214AC), higher RθJA (110 °C/W) | Limited to lower-energy transients; less suitable for under-hood automotive or high-density layouts | Choose for space-constrained designs where 800 W rating is unnecessary and legacy footprint compatibility is needed |
Compared with SMB8J10CAHM3_A/H, SMB8J10CAHE3_A/H lacks halogen-free and AEC-Q101 compliance-critical for Tier 1 automotive BOMs-while SMAJ10CA trades power handling and thermal performance for broader legacy availability, making it appropriate only for non-automotive, lower-surge environments.

FAQ
What is the clamping voltage of SMB8J10CAHM3_A/H at its rated peak pulse current?
The SMB8J10CAHM3_A/H has a maximum clamping voltage (VC) of 17.0 V at 10 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMB8J10CAHM3_A/H maintains this clamping performance consistently across its qualified operating temperature range.
Is SMB8J10CAHM3_A/H suitable for automotive applications?
Yes, SMB8J10CAHM3_A/H is AEC-Q101 qualified and halogen-free, meeting automotive reliability and environmental requirements for use in engine control units, ADAS sensors, and body electronics. Its SMB package, 150 °C junction rating, and validated surge performance make SMB8J10CAHM3_A/H appropriate for under-hood and chassis-mounted systems subject to ISO 7637-2 and ISO 16750-2 stress profiles.
How does the bidirectional configuration of SMB8J10CAHM3_A/H affect its placement in circuit design?
The SMB8J10CAHM3_A/H has no polarity marking and functions identically in either orientation, enabling direct placement across differential lines (e.g., CAN_H/CAN_L) or AC-coupled signal paths without layout constraints. Unlike unidirectional TVS devices, SMB8J10CAHM3_A/H eliminates the need for orientation verification during automated assembly and supports symmetric surge suppression critical for noise-immune communication interfaces.
What is the thermal resistance from junction to lead (RθJL) for SMB8J10CAHM3_A/H?
The SMB8J10CAHM3_A/H has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard mounting conditions (0.2" × 0.2" copper pads per terminal). This low value enables efficient heat transfer to the PCB, supporting sustained surge duty cycles and high ambient temperature operation-key for SMB8J10CAHM3_A/H deployment in thermally constrained automotive modules.
Does SMB8J10CAHM3_A/H meet JEDEC moisture sensitivity level requirements?
Yes, SMB8J10CAHM3_A/H meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This classification confirms that the device can be subjected to standard lead-free SMT reflow profiles without preconditioning or baking, simplifying manufacturing flow and ensuring SMB8J10CAHM3_A/H compatibility with high-volume automated assembly processes.
