Product details
Overview
SMBJ10CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection on signal and power lines. It features a 10 V standoff voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), clamping voltage of 17.0 V at 35.3 A, and operates across –55 °C to +150 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor signal lines in industrial motor drives and telecom interfaces.
For engineers reviewing the SMBJ10CAHE3_B/H datasheet, SMBJ10CAHE3_B/H pinout, SMBJ10CAHE3_B/H application, or SMBJ10CAHE3_B/H equivalent, this device delivers verified bidirectional clamping performance, AEC-Q101 qualification for automotive-grade reliability, UL 497B recognition, and SMB (DO-214AA) package compatibility with automated SMT assembly.
Technical Context
This bidirectional TVS diode functions as a voltage-clamped shunt protector: during transient events exceeding VWM, it avalanches symmetrically in both directions to limit voltage across protected circuit nodes. Its glass-passivated junction ensures stable leakage (<1 µA at 10 V) and fast response (<1 ns), while low incremental surge resistance enables effective energy diversion without thermal runaway.
The SMBJ10CAHE3_B/H is rated for 600 W peak pulse power under standard 10/1000 µs waveform, derated linearly above 25 °C ambient per Fig. 2, and supports repetitive surges at 0.01% duty cycle. Its MSL Level 1 rating (JEDEC J-STD-020) and matte tin-plated leads ensure compatibility with lead-free reflow profiles up to 260 °C peak.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA-E3/52 | Commercial-grade (non-AEC-Q101), same electrical specs and SMB package; RoHS-compliant but not automotive qualified. | Lacks automotive qualification and UL 497B recognition; suitable for consumer/industrial equipment without safety certification mandates. | Select when cost sensitivity outweighs automotive reliability requirements and no end-equipment safety listing is needed. |
| SAC10CA | Same VWM/VBR/VC ratings but in SOD-123FL package; lower PPPM (400 W), higher RθJA (150 °C/W). | Reduced surge handling and thermal performance; limited to low-energy transients in space-constrained portable designs. | Choose only for compact layouts where 600 W capability is unnecessary and board area is prioritized over robustness. |

FAQ
What is the clamping voltage of SMBJ10CAHE3_B/H at its rated peak pulse current?
The SMBJ10CAHE3_B/H has a maximum clamping voltage (VC) of 17.0 V at 35.3 A peak pulse current (IPPM), measured under the standardized 10/1000 µs waveform. This value is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88392 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ10CAHE3_B/H maintains this clamping performance across its full operating temperature range.
Is SMBJ10CAHE3_B/H suitable for automotive applications?
Yes, SMBJ10CAHE3_B/H is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix, indicating RoHS-compliant and automotive-grade construction. It meets stress test requirements for temperature cycling, humidity, mechanical shock, and surge immunity relevant to body electronics and infotainment systems. The SMBJ10CAHE3_B/H is listed in Vishay's automotive ordering matrix and carries UL 497B recognition for telecom/data line protection in vehicle networks.
How does the bidirectional configuration of SMBJ10CAHE3_B/H affect its circuit placement?
The SMBJ10CAHE3_B/H has no polarity marking and conducts symmetrically in both directions, allowing direct placement across any two-node interface without orientation concerns-ideal for AC-coupled lines like RS-485, CAN, or audio signals. Unlike unidirectional TVS diodes, it eliminates the need for series DC blocking capacitors or dual-diode arrangements. Its bidirectional behavior is verified in the datasheet's "DEVICES FOR BIDIRECTION APPLICATIONS" section and applies across the full VBR range.
What is the thermal resistance of SMBJ10CAHE3_B/H, and how does it impact layout design?
The SMBJ10CAHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Figure 6 of the datasheet. This value directly governs allowable power dissipation: at 50 °C ambient, the 5.0 W steady-state power rating requires careful copper area allocation. Layouts must replicate the datasheet-recommended pad dimensions to achieve rated surge performance and avoid thermal derating penalties.
Does SMBJ10CAHE3_B/H meet industry safety standards for end-equipment certification?
Yes, SMBJ10CAHE3_B/H is Underwriters Laboratories (UL) recognized under standard UL 497B (file E136766) for protectors used in telecommunications and data line applications. This recognition covers both unidirectional and bidirectional variants and validates its suitability for inclusion in safety-certified end equipment such as industrial gateways and automotive ECUs. The UL listing is explicitly cited in the "Notes" section of the Vishay SMBJ5.0A–SMBJ188A datasheet (document 88392).
