Product details
Overview
SMBJ110CAHE3_A/I 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 power and signal lines. It features a 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤177 V at 3.4 A peak surge current - deployed in industrial sensor interfaces and telecom line protection.
For engineers reviewing the SMBJ110CAHE3_A/I datasheet, SMBJ110CAHE3_A/I pinout, SMBJ110CAHE3_A/I application, or SMBJ110CAHE3_A/I equivalent, this device serves as a robust, AEC-Q101-qualified transient suppressor for bidirectional DC bus and AC-coupled signal line protection where low clamping ratio, fast response (<1 ns), and MSL Level 1 reflow compatibility are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max (122 V / 135 V), ID ≤1.0 µA at VWM, and VC = 177 V at IPPM = 3.4 A under 10/1000 µs waveform. Its glass-passivated junction ensures stable leakage and low incremental surge resistance.
The device is rated for TJ = –55 °C to +150 °C, features RθJA = 100 °C/W, and meets J-STD-020 MSL Level 1 (260 °C peak reflow). The HE3 suffix confirms RoHS-compliance and AEC-Q101 qualification - critical for automotive infotainment and body control modules requiring long-term reliability under thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - maximum continuous reverse operating voltage before clamping begins; defines safe working margin for 120 VAC-derived rails or 100 VDC systems. |
| VBR (min/max) | 122 V / 135 V at IT = 1 mA - tight breakdown window ensures predictable turn-on and avoids premature conduction during normal operation. |
| VC @ IPPM | 177 V at 3.4 A (10/1000 µs) - clamping voltage directly limits downstream IC stress; 1.6× VWM ratio indicates high efficiency for its power class. |
| PPPM | 600 W - peak transient energy handling capability under standardized surge waveform; sufficient for IEC 61000-4-5 Level 3 (1 kV/2 Ω) events. |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves battery life and prevents false triggering in high-impedance sensor bias networks. |
| TJ max. | +150 °C - enables deployment in under-hood automotive environments and industrial enclosures without derating below full power. |
| Package | SMB (DO-214AA) - 0.205" × 0.130" footprint with 0.086" cathode band; compatible with automated SMT placement and IPC-7351B land patterns. |
Pinout & Package
Two-terminal bidirectional device in SMB (DO-214AA) package; no polarity marking - symmetrical terminals function identically in either orientation. Mounting uses standard 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per Vishay recommended layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional surge path | Either terminal accepts positive or negative transients; no DC bias dependency - ideal for AC-coupled data lines and floating power rails. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Handles repetitive surges up to 0.01% duty cycle without degradation - suitable for motor drive feedback loops with frequent switching noise. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade temperature cycling, humidity, and mechanical shock - supports use in ADAS camera power supplies and gateway ECUs. |
| MSL Level 1, 260 °C peak reflow | Eliminates pre-baking requirement and supports single-pass lead-free assembly - reduces manufacturing cost and process complexity. |
| Low clamping ratio (VC/VWM ≈ 1.61) | Minimizes overvoltage exposure to protected ICs - extends lifetime of RS-485 transceivers and CAN FD controllers in noisy industrial networks. |
| Glass-passivated junction | Ensures stable VBR and ID over time and temperature - critical for field-deployed equipment requiring >10-year operational integrity. |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |

FAQ
What is the clamping voltage of SMBJ110CAHE3_A/I at its rated peak pulse current?
The SMBJ110CAHE3_A/I clamps to a maximum of 177 V at its specified peak pulse current (IPPM) of 3.4 A under the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and reflects worst-case device behavior at TA = 25 °C with recommended PCB pad layout - ensuring downstream circuitry remains within safe overvoltage limits during surge events.
Is SMBJ110CAHE3_A/I suitable for automotive applications?
Yes, SMBJ110CAHE3_A/I is AEC-Q101 qualified (confirmed by the HE3 suffix), making it suitable for automotive applications including body control modules, infotainment power rails, and sensor interfaces. It undergoes stress testing for temperature cycling, humidity, and mechanical shock per AEC-Q101 requirements - supporting deployment in under-hood and cabin environments up to +150 °C junction temperature.
How does the bidirectional design of SMBJ110CAHE3_A/I affect its circuit implementation?
The bidirectional design of SMBJ110CAHE3_A/I means it functions identically regardless of voltage polarity - eliminating need for orientation during placement and enabling protection of AC-coupled signals or floating DC buses. Unlike unidirectional TVS diodes, it requires no cathode/anode alignment, simplifying layout and reducing assembly errors in differential interfaces like RS-485 or LIN bus stubs.
What is the maximum leakage current of SMBJ110CAHE3_A/I at its stand-off voltage?
The SMBJ110CAHE3_A/I exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 110 V stand-off voltage (VWM), measured at TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor circuits and minimizes quiescent power loss in battery-powered systems - critical for always-on automotive modules and portable industrial instruments.
Does SMBJ110CAHE3_A/I require special PCB layout considerations?
Yes - Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and thermal performance. Smaller pads increase thermal resistance and reduce surge capability. The SMB (DO-214AA) footprint also requires adherence to IPC-7351B land pattern guidelines to ensure solder joint reliability during reflow and thermal cycling.
