Product details
Overview
SMCJ16CAHE3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 16 V standoff voltage (VWM), 26.0 V maximum clamping voltage (VC) at 57.7 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed across automotive sensor signal lines, industrial I/O ports, and DC power rails.
For engineers reviewing the SMCJ16CAHE3_A/H datasheet, SMCJ16CAHE3_A/H pinout, SMCJ16CAHE3_A/H application, or SMCJ16CAHE3_A/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, low incremental surge resistance, and compatibility with automated SMT placement on 8 mm × 8 mm copper pads.
Technical Context
This device operates as a voltage-clamped crowbar during transients: when reverse voltage exceeds its breakdown range (17.8–19.7 V at 1 mA test current), it enters avalanche conduction to limit downstream voltage to ≤26.0 V. Its bidirectional structure enables symmetrical clamping on AC-coupled or floating lines without polarity concerns.
Thermally, it sustains 150 °C junction temperature with RθJA = 75 °C/W and RθJL = 15 °C/W, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. The glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ps).
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 mA - Ensures reliable turn-on margin above VWM for noise immunity |
| VC @ IPPM | 26.0 V at 57.7 A - Clamped voltage seen by protected circuit during 10/1000 μs surge |
| PPPM | 1500 W - Peak transient energy absorption capability under standardized waveform |
| ID @ VWM | ≤1.0 μA - Low leakage preserves signal integrity and battery life in always-on systems |
| TJ max | +150 °C - Enables operation in under-hood automotive and high-temperature industrial environments |
| Package | SMC (DO-214AB) - Surface-mount footprint compatible with IPC-7351B standard pad layout |
Pinout & Package
SMCJ16CAHE3_A/H uses the SMC (DO-214AB) package: a low-profile, molded plastic case with matte tin-plated leads solderable per J-STD-002. Bidirectional construction means no polarity marking; both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (reverse bias) | One side of symmetrical avalanche junction; conducts during positive or negative overvoltage |
| Cathode | Transient current entry (reverse bias) | Other side of symmetrical avalanche junction; identical function to Anode in bidirectional mode |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| 1500 W peak pulse power | Withstands ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 surge events without degradation |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes voltage overshoot during fast transients, protecting 3.3 V/5 V logic interfaces |
| MSL Level 1 moisture sensitivity | Enables standard reflow without baking, reducing manufacturing cost and handling risk |
| Glass-passivated junction | Ensures long-term parameter stability and low leakage drift over 10+ year service life |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and inductive switching spikes in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector interface to clamp ±200 V transients before reaching signal conditioning ICs. Use Value: Prevents latch-up or permanent damage to 5 V rail and microcontroller GPIOs while maintaining <1.0 μA leakage at 16 V standby. | Use Scenario: Shielding digital input modules in programmable logic controllers from field-wiring induced surges (e.g., motor contactor bounce, relay coil kickback). IC Role / Device Role / Timing Role: Standoff-rated TVS on 24 V DC input lines, absorbing up to 1500 W pulses without derating at 85 °C ambient. Use Value: Eliminates need for external series impedance or RC filters, preserving signal edge integrity for 10 kHz digital inputs. |
| DC Power Rail Protection | Telecom Line Interface |
Use Scenario: Safeguarding 12–24 V intermediate distribution rails in base station power supplies against lightning-induced surges and hot-swap transients. IC Role / Device Role / Timing Role: Primary clamping device mounted adjacent to DC-DC converter input, coordinated with upstream fuses for selective coordination. Use Value: Limits rail collapse to ≤26.0 V during 57.7 A surge, preventing brownout resets in downstream FPGAs and PMICs. | Use Scenario: Protecting Ethernet PHY magnetics and PoE controller interfaces from induced surges on outdoor telecom line cards. IC Role / Device Role / Timing Role: Bidirectional TVS across differential pairs (e.g., MDI-X) to suppress common-mode transients without distorting 100BASE-TX eye diagrams. Use Value: Maintains <10 pF junction capacitance at zero bias, avoiding signal attenuation above 100 MHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC16CA | Lower PPPM (600 W), same VWM (16 V), DO-214AA package (smaller thermal mass) | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when cost sensitivity outweighs automotive qualification and surge margin requirements |
| SMCJ16CAHM3_A/H | Identical electrical specs; halogen-free molding compound and lead finish | Same AEC-Q101 qualification but meets stricter environmental compliance (IEC 61249-2-21) | Choose for RoHS + halogen-free mandates in EU automotive Tier 1 supply chains |
Compared with SMCJ16CAHE3_A/H, SAC16CA offers lower surge capacity and no automotive qualification, while SMCJ16CAHM3_A/H delivers identical protection performance with enhanced material compliance - enabling direct substitution where halogen-free content is contractually required.

FAQ
What is the breakdown voltage range of SMCJ16CAHE3_A/H?
The SMCJ16CAHE3_A/H has a minimum breakdown voltage (VBR) of 17.8 V and a maximum of 19.7 V at 1 mA test current, measured per ANSI/IEEE C62.35. This verified range ensures consistent turn-on behavior across production lots and supports reliable coordination with downstream overvoltage thresholds in circuits protected by SMCJ16CAHE3_A/H.
Is SMCJ16CAHE3_A/H suitable for automotive applications?
Yes, SMCJ16CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use via its HE3 suffix. It undergoes stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC standards - making SMCJ16CAHE3_A/H appropriate for engine control units, ADAS sensor interfaces, and body electronics where reliability under thermal and electrical stress is mandatory.
What does the "CA" suffix indicate in SMCJ16CAHE3_A/H?
The "CA" suffix in SMCJ16CAHE3_A/H denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both polarities without requiring orientation during PCB placement. Unlike unidirectional variants (e.g., SMCJ16A), SMCJ16CAHE3_A/H has no cathode band marking and clamps equally on positive and negative voltage excursions - critical for AC-coupled or floating signal lines.
How is thermal performance characterized for SMCJ16CAHE3_A/H?
SMCJ16CAHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W, measured on 8.0 mm × 8.0 mm copper pads per JEDEC standards. These values enable accurate thermal modeling in high-power surge scenarios and confirm that SMCJ16CAHE3_A/H remains within its 150 °C maximum junction temperature limit even under repeated 1500 W pulses with proper board layout.
What packaging and reel options are available for SMCJ16CAHE3_A/H?
