Product details
Overview
SMBG10CAHE3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of signal and power lines. It features a 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, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBG10CAHE3/52 datasheet, SMBG10CAHE3/52 pinout, SMBG10CAHE3/52 application, or SMBG10CAHE3/52 equivalent, this AEC-Q101 qualified, RoHS-compliant TVS offers verified bidirectional surge suppression for automotive sensor interfaces, industrial I/O protection, and telecom line conditioning where low-leakage (<5.0 µA at VWM) and fast response are critical.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical electrical characteristics in forward and reverse directions - confirmed by VBR min/max and VC values matching for both directions. Its glass-passivated junction ensures stable leakage and clamping performance over temperature (-55 °C to +150 °C).
The device uses a low-inductance SMBG (DO-215AA) surface-mount package with matte tin-plated leads, rated MSL Level 1 (260 °C reflow peak), and achieves 100 °C/W junction-to-ambient thermal resistance on standard 5.0 mm × 5.0 mm copper pads - enabling reliable energy dissipation during repetitive 0.01% duty cycle transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse/forward voltage before clamping begins; defines safe operating window for protected circuitry. |

Applications
| Automotive Sensor Protection | Industrial I/O Protection |
|---|---|
Use Scenario: Protecting ABS wheel speed sensors and engine crankshaft position sensors from load dump and inductive switching transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bidirectional TVS placed across sensor supply and ground, clamping transients before they reach the analog front-end of the MCU or dedicated sensor signal conditioner. Use Value: Maintains signal fidelity during ISO 7637-2 Pulse 5b (load dump up to 60 V) while limiting clamped voltage to ≤17.0 V - preventing latch-up or damage to 5 V tolerant sensor interface ICs. | Use Scenario: Safeguarding PLC digital input modules connected to 24 V DC field wiring exposed to relay coil flyback and EMI coupling. IC Role / Device Role / Timing Role: Placed between field input terminal and controller-side optocoupler or Schmitt trigger input, absorbing repetitive 600 W surges without degradation. Use Value: Enables >100,000 surge cycles at 0.01% duty factor due to low incremental surge resistance and 150 °C TJ rating - extending field unit service life in factory automation. |
| Telecom Line Conditioning | Consumer USB Port Protection |
Use Scenario: Shielding RS-485 transceivers in building management systems from lightning-induced surges on long outdoor data runs. IC Role / Device Role / Timing Role: Connected differentially across A/B bus lines and common-mode to ground, providing symmetrical clamping for common- and differential-mode transients. Use Value: Delivers matched VC = 17.0 V in both directions - prevents data corruption by holding bus differential voltage within transceiver common-mode range during 10/1000 µs surges. | Use Scenario: Adding secondary overvoltage protection on VBUS line of USB 2.0 ports in smart home hubs exposed to hot-plug and adapter fault conditions. IC Role / Device Role / Timing Role: Positioned upstream of USB power switch IC, clamping VBUS to ≤17.0 V during 100 V/1 µs ESD events per IEC 61000-4-2. Use Value: Achieves <5.0 µA leakage at 5 V nominal - avoids standby current drain while meeting USB-IF ESD immunity requirements without compromising efficiency. |
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 | Same VWM (10 V), but lower PPPM = 600 W (same), higher VC = 17.0 V (identical), but non-AEC-Q101 rated and MSL Level 2. | Lacks automotive qualification and tighter thermal reflow margin - suitable for commercial/industrial only. | Select SMBJ10CA when AEC-Q101 compliance and MSL Level 1 are not required; verify PCB pad thermal relief for 260 °C reflow. |
| SMCJ10CA | Same VWM/VBR/VC, but larger SMC (DO-214AB) package, higher IFSM = 100 A (vs. N/A for bidirectional), PPPM = 1500 W. | Higher power handling and thermal mass - suited for higher-energy surge environments but requires larger board area. | Choose SMCJ10CA where system-level surge tests exceed 600 W or where board space allows larger footprint and enhanced thermal dissipation. |
Compared with SMBG10CAHE3/52, SMBJ10CA offers identical electrical protection but lacks automotive qualification and stricter reflow compatibility, while SMCJ10CA provides higher surge capacity in a larger package - making SMBG10CAHE3/52 optimal for space-constrained, AEC-Q101–mandated automotive and industrial edge nodes.

FAQ
What is the clamping voltage of SMBG10CAHE3/52 at its rated peak pulse current?
The SMBG10CAHE3/52 has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 35.3 A, measured using the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and confirms effective overvoltage limiting for downstream 5 V or 3.3 V logic circuits. The SMBG10CAHE3/52 maintains this clamping performance bidirectionally, supporting robust protection in AC-coupled or floating signal paths.
Is SMBG10CAHE3/52 suitable for automotive applications?
Yes, SMBG10CAHE3/52 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and chassis-mounted electronics. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and operation from –55 °C to +150 °C junction temperature - all validated per JESD22 test standards. The SMBG10CAHE3/52 is commonly deployed in engine control units, ADAS sensor interfaces, and body electronics where ISO 7637-2 and ISO 16750-2 compliance is required.
Does SMBG10CAHE3/52 have polarity markings on the package?
No, SMBG10CAHE3/52 does not feature a cathode band or other polarity marking because it is a bidirectional TVS diode. Both terminals are functionally identical and interchangeable - the device clamps symmetrically in either direction. This eliminates orientation errors during automated placement and simplifies PCB layout for differential or AC signal lines. The SMBG10CAHE3/52 datasheet explicitly states "no marking on bidirectional types" in the mechanical notes section.
What is the maximum leakage current of SMBG10CAHE3/52 at its stand-off voltage?
The SMBG10CAHE3/52 exhibits a maximum reverse leakage current (ID) of 5.0 µA at its 10 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage remains stable across temperature and ensures minimal impact on battery-powered or high-impedance sensor circuits. The SMBG10CAHE3/52 achieves this performance via its glass-passivated chip junction, which also contributes to long-term parameter stability in harsh environments.
How does the SMBG10CAHE3/52 package compare to SMBJ and SMCJ equivalents in size and thermal performance?
The SMBG10CAHE3/52 uses the compact SMBG (DO-215AA) package - smaller than SMBJ (DO-214AA) and significantly smaller than SMCJ (DO-214AB). Its RθJA is 100 °C/W on 5.0 mm × 5.0 mm copper pads, balancing miniaturization with adequate thermal dissipation for 600 W pulses. Unlike SMBJ, SMBG10CAHE3/52 is AEC-Q101 qualified and MSL Level 1 rated; unlike SMCJ, it saves board space while maintaining identical VWM/VC specs - making SMBG10CAHE3/52 ideal for space-constrained automotive modules.
