Product details
Overview
SMBJ16CAHE3_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 or power lines. It features a 16 V standoff voltage (VWM), 17.8–19.7 V breakdown range (VBR), 26.0 V maximum clamping voltage (VC) at 23.1 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 SMBJ16CAHE3_A/H datasheet, SMBJ16CAHE3_A/H pinout, SMBJ16CAHE3_A/H application, or SMBJ16CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–55 to +150 °C), and compliance with UL 497B surge protector classification.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the low incremental surge resistance supports fast, repeatable clamping under repetitive transients.
The device meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and is qualified to AEC-Q101 for automotive-grade reliability - confirmed by the "HE3" suffix and ordering code structure in Vishay's documentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 17.8 V / 19.7 V at 1.0 mA test current - defines guaranteed breakdown threshold window |
| VC @ IPPM | 26.0 V at 23.1 A - clamping voltage during 10/1000 µs surge, limiting stress on downstream components |
| PPPM | 600 W - peak transient energy absorption capacity under standardized waveform |
| ID @ VWM | <1.0 µA - ultra-low reverse leakage preserves signal integrity in high-impedance circuits |
| TJ max | +150 °C - enables operation in under-hood or enclosed industrial environments |
| RθJA | 100 °C/W - thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads |

| UL 497B recognition | Qualified as a listed surge protector (QVGQ2, E136766), simplifying safety certification for end equipment |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |
|---|---|
Use Scenario: Protection of gate driver signal lines against inductive kickback from relay or solenoid switching. IC Role / Device Role / Timing Role: Transient voltage suppressor placed directly at MOSFET gate input to clamp spikes before they reach driver IC. Use Value: Limits gate-source voltage to ≤26.0 V during 600 W surges, preventing oxide breakdown and ensuring long-term reliability of 40 V-rated logic-level MOSFETs. |
Use Scenario: Safeguarding LIN bus transceiver inputs from load dump and jump-start induced transients in door module ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS connected across LIN data pair to absorb ±100 V/500 ms transients per ISO 7637-2 Pulse 5a. Use Value: Maintains signal integrity below 26.0 V clamping level while supporting <1.0 µA leakage to avoid LIN bias current errors. |
| Telecom Power Supply Inputs | Consumer Sensor Interface Boards |
Use Scenario: Input-stage surge suppression on 24 V DC power rails feeding PoE-powered network switches. IC Role / Device Role / Timing Role: Primary TVS on bulk input rail, coordinated with upstream fuse and downstream DC-DC converter overvoltage protection. Use Value: Absorbs 600 W transients with 23.1 A peak current handling, reducing need for oversized input capacitors or secondary crowbar circuits. |
Use Scenario: ESD and lightning-induced transient protection on analog output lines of MEMS pressure sensors in smart home hubs. IC Role / Device Role / Timing Role: Low-capacitance TVS placed at sensor PCB edge connector to shunt transients before reaching ADC front-end. Use Value: Clamps 8 kV contact ESD events (IEC 61000-4-2) within nanoseconds while adding negligible capacitance to 0–10 V analog outputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA-M3 | Halogen-free, RoHS-compliant, commercial grade - lacks AEC-Q101 qualification | Not approved for automotive under-hood use; suitable for industrial control panels with lower reliability requirements | Select when halogen-free compliance is mandatory and automotive qualification is unnecessary |
| SMBJ16AHE3_A/H | Unidirectional version - cathode-marked, asymmetric clamping (forward VF ≈ 3.5 V) | Requires correct polarity placement; unsuitable for AC or differential signals without external rectification | Choose only for DC supply rail protection where polarity is fixed and forward conduction must be blocked |
Compared with SMBJ16CAHE3_A/H, the M3 variant trades automotive qualification for halogen-free materials, while the unidirectional SMBJ16AHE3_A/H requires strict polarity alignment and cannot protect bidirectional interfaces - making SMBJ16CAHE3_A/H the sole choice for polarity-agnostic surge suppression in LIN, RS-485, or sensor bridge applications.

FAQ
What does the "CA" suffix indicate in SMBJ16CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration, meaning SMBJ16CAHE3_A/H provides symmetrical clamping in both polarities - essential for protecting AC-coupled signals, differential buses like LIN or CAN, or floating sensor outputs where voltage polarity may reverse during transients.
Is SMBJ16CAHE3_A/H suitable for automotive applications?
Yes - SMBJ16CAHE3_A/H carries the "HE3" suffix confirming AEC-Q101 qualification, validated for automotive use including body electronics, infotainment systems, and ADAS sensor interfaces. Its –55 to +150 °C operating range and MSL Level 1 reflow compatibility meet stringent automotive manufacturing requirements.
How does SMBJ16CAHE3_A/H differ from unidirectional SMBJ16AHE3_A/H?
SMBJ16CAHE3_A/H is bidirectional with no polarity marking and identical clamping in both directions, whereas SMBJ16AHE3_A/H is unidirectional with a cathode band and conducts forward current below 3.5 V. The bidirectional version avoids incorrect orientation risk and supports AC/differential protection - critical for SMBJ16CAHE3_A/H deployment in LIN or RS-485 interfaces.
What is the maximum clamping voltage of SMBJ16CAHE3_A/H under surge conditions?
The maximum clamping voltage (VC) of SMBJ16CAHE3_A/H is 26.0 V at 23.1 A peak pulse current (IPPM) with a 10/1000 µs waveform - measured per IEC 61000-4-5 standards. This value ensures downstream 3.3 V or 5 V logic ICs remain within absolute maximum ratings during surge events.
Does SMBJ16CAHE3_A/H require special PCB layout considerations?
Yes - Vishay specifies mounting on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and thermal resistance of 100 °C/W. Reduced pad area degrades surge handling and increases junction temperature, risking premature failure during repetitive transients.
