Product details
Overview
SMBJ10CAHM3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 10 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the SMBJ10CAHM3_B/H datasheet, SMBJ10CAHM3_B/H pinout, SMBJ10CAHM3_B/H application, or SMBJ10CAHM3_B/H equivalent, this device is selected for robust ESD and surge protection where bidirectional clamping, low clamping ratio (VC/VBR ≈ 1.53), and AEC-Q101 qualification (via HM3 suffix) are required in space-constrained PCB layouts.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 µA at VWM), while the low incremental surge resistance enables rapid energy absorption during transient events.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads. Its MSL Level 1 rating (per J-STD-020) and matte tin-plated leads support lead-free reflow assembly without whisker risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 11.1 V / 12.3 V at 10 mA - guaranteed breakdown range defining turn-on threshold |
| VC @ IPPM | 17.0 V at 35.3 A - clamped voltage during 600 W transient, limiting stress on downstream components |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform, enabling IEC 61000-4-5 Level 4 compliance |
| ID @ VWM | ≤1.0 µA - ultra-low reverse leakage preserves signal integrity in high-impedance circuits |

|---|---|
Use Scenario: Protection of gate drivers and feedback signal lines against inductive kickback from relay coils and solenoids. IC Role / Device Role / Timing Role: Bidirectional TVS clamps transient spikes before they reach microcontroller GPIO or op-amp inputs.

Use Scenario: Shielding LIN bus or analog sensor outputs (e.g., pressure, temperature) from load-dump and jump-start transients. IC Role / Device Role / Timing Role: Fast-response voltage clamp placed directly at connector entry point. Use Value: Maintains signal fidelity under ISO 7637-2 Pulse 5a (load dump) with <1 ns response time and no degradation after repeated surges. |
| Telecom Power Supply Input | Consumer USB-C Port Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CAHE3_B/H | Same electrical specs; RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification | Suitable for commercial-grade industrial designs where automotive qualification is unnecessary | Select when cost sensitivity outweighs halogen-free or automotive reliability requirements |
| SMAJ10CAHM3 | Lower PPPM (400 W); same VWM/VBR/VC but reduced IPPM (24.7 A); SMA package (smaller footprint, higher RθJA) | Acceptable for lower-energy transients or space-constrained layouts where 600 W margin is not required | Choose only if board area is critical and surge threat level is limited to IEC 61000-4-5 Level 2 |
Compared with SMBJ10CAHM3_B/H, the HE3 variant trades halogen-free construction and AEC-Q101 validation for lower cost, while the SMAJ10CAHM3 reduces surge capacity and thermal performance to fit tighter footprints - neither offers drop-in replacement without verifying layout clearance and system-level surge margin.

FAQ
What does the "HM3" suffix indicate in SMBJ10CAHM3_B/H?
The HM3 suffix denotes halogen-free, RoHS-compliant construction with full AEC-Q101 qualification - verified through temperature cycling, highly accelerated life testing (HALT), and ESD robustness validation. SMBJ10CAHM3_B/H meets automotive-grade reliability standards while maintaining identical electrical specs to non-qualified variants.
Is SMBJ10CAHM3_B/H unidirectional or bidirectional?
SMBJ10CAHM3_B/H is a bidirectional TVS diode, as confirmed by the "CA" designation in its part number and explicit documentation stating "Electrical characteristics apply in both directions." It has no polarity marking and clamps symmetrically for positive and negative transients.
What is the maximum clamping voltage of SMBJ10CAHM3_B/H at rated surge current?
The maximum clamping voltage (VC) of SMBJ10CAHM3_B/H is 17.0 V at 35.3 A peak pulse current (IPPM), measured with a 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can SMBJ10CAHM3_B/H replace SMBJ10A in a design?
No - SMBJ10A is unidirectional (cathode-banded), while SMBJ10CAHM3_B/H is bidirectional with symmetrical conduction. Substituting SMBJ10CAHM3_B/H for SMBJ10A would eliminate polarity dependency but may alter circuit behavior in DC-biased applications; layout and functional validation are required.
What PCB pad layout is recommended for optimal thermal performance of SMBJ10CAHM3_B/H?
Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve the rated 600 W pulse power and 100 °C/W thermal resistance. Reducing pad size degrades surge capability and increases junction temperature - refer to Figure 6 in Document 88392 for exact copper area guidelines.
