Product details
Overview
SMBJ10CAHE3_A/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 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs waveform), used in industrial sensor interface protection.
For engineers reviewing the SMBJ10CAHE3_A/H datasheet, SMBJ10CAHE3_A/H pinout, SMBJ10CAHE3_A/H application, or SMBJ10CAHE3_A/H equivalent, this device is selected for robust ESD and surge immunity in bidirectional AC-coupled or floating signal paths where polarity-agnostic clamping is required - especially in automotive-grade sensor units, telecom line interfaces, and industrial I/O modules meeting AEC-Q101 reliability requirements.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max (11.1–12.3 V), VC (17.0 V), and IPPM (35.3 A) in either direction. Its glass-passivated junction ensures stable leakage (<5.0 µA at VWM) and low incremental surge resistance, enabling fast response to sub-nanosecond transients without degradation under repetitive stress.
Thermally rated for TJ = –55 °C to +150 °C, it delivers 5.0 W steady-state power dissipation at TA = 50 °C and maintains clamping performance up to 150 °C junction temperature. The SMB package supports automated placement and meets MSL Level 1 (260 °C peak reflow), with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.

Applications
| Automotive Sensor Protection | Industrial Analog Input Protection |
|---|---|
|
Use Scenario: Protecting LIN bus-connected temperature and pressure sensors in engine compartments exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS placed across sensor supply and ground to clamp ±100 V transients within 1 ns. Use Value: Prevents sensor IC latch-up and output corruption while maintaining <5 µA leakage to avoid DC offset errors in ratiometric measurements. |
Use Scenario: Shielding 4–20 mA current loop receivers from induced surges in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Clamps common-mode transients between loop supply and return, referenced to local ground plane. Use Value: Ensures uninterrupted analog signal acquisition during 2 kV EFT bursts (IEC 61000-4-4) without resetting ADC or isolator ICs. |
| Telecom Line Interface | USB 2.0 Data Line Protection |
|
Use Scenario: Safeguarding RS-485 transceivers in outdoor telecom cabinets subjected to lightning-induced surges on twisted-pair lines. IC Role / Device Role / Timing Role: Placed differentially across A/B lines to suppress common-mode and differential-mode transients simultaneously. Use Value: Maintains signal integrity below 17 V clamping level - well below RS-485 receiver absolute max rating (±12 V) and avoids false triggering. |
Use Scenario: Protecting USB 2.0 D+/D− lines in portable medical devices against ESD events per IEC 61000-4-2 ±15 kV contact discharge. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS shunting each data line to ground to divert ESD current away from PHY. Use Value: Limits clamping voltage to 17.0 V during 30 A ESD pulse - prevents PHY damage while preserving signal rise/fall times (<1 ns response). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA-E3/52 | Commercial-grade (non-AEC-Q101), same VWM/VBR/VC/PPPM, RoHS-compliant but not automotive qualified. | Limited to non-automotive industrial or consumer use; lacks extended temperature validation and lifetime reliability testing. | Select when cost-sensitive and operating environment stays ≤125 °C with no automotive qualification mandate. |
| SAC10CA | Same VWM (10 V) and bidirectional function, but lower PPPM (400 W), higher VC (24 V), and DO-214AC (SMA) package. | Less robust for high-energy surges; larger package footprint may conflict with dense PCB layouts. | Acceptable only for low-risk environments like office equipment where IEC 61000-4-5 Level 2 (1 kV) suffices. |
Compared with SMBJ10CAHE3_A/H, the E3/52 variant offers identical electrical specs but omits AEC-Q101 validation and high-temp operational assurance, while SAC10CA trades surge capacity and compactness for cost - making SMBJ10CAHE3_A/H the optimal choice for automotive and mission-critical industrial designs demanding validated 150 °C operation and 600 W immunity.

This value is measured across both terminals under bidirectional surge conditions and ensures downstream components such as microcontrollers or transceivers remain within safe voltage limits during transient events.
Is SMBJ10CAHE3_A/H suitable for automotive applications?
Yes, SMBJ10CAHE3_A/H is AEC-Q101 qualified, as indicated by the "HE3" suffix, and rated for operation from –55 °C to +150 °C. It is specifically designed for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces where sustained reliability under thermal and electrical stress is mandatory - confirmed by Vishay's qualification test reports.
How does the bidirectional nature of SMBJ10CAHE3_A/H affect its placement in circuit design?
The SMBJ10CAHE3_A/H has no polarity marking and functions identically in both directions, allowing direct placement across any two nodes requiring symmetrical overvoltage protection - such as differential signal pairs, transformer secondaries, or floating sensor bridges. This eliminates orientation errors during assembly and simplifies layout versus unidirectional alternatives that require cathode alignment.
What is the maximum leakage current of SMBJ10CAHE3_A/H at its stand-off voltage?
At its 10 V stand-off voltage (VWM), the SMBJ10CAHE3_A/H exhibits a maximum reverse leakage current (ID) of 5.0 µA at 25 °C. This low leakage preserves signal fidelity in high-impedance analog paths and minimizes power loss in battery-powered sensor nodes - verified per the Vishay SMBJ5.0A–SMBJ188A datasheet revision 09-Jan-2024.
Does SMBJ10CAHE3_A/H meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, SMBJ10CAHE3_A/H meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C.
