Product details
Overview
SMCJ100CAHE3_A/I 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 100 V stand-off voltage (VWM), 162 V maximum clamping voltage (VC) at 9.3 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) with 10/1000 µs waveform - deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the SMCJ100CAHE3_A/I datasheet, SMCJ100CAHE3_A/I pinout, SMCJ100CAHE3_A/I application, or SMCJ100CAHE3_A/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compliance with UL 497B for surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding its breakdown voltage (VBR min = 111 V, max = 123 V), it avalanches to divert surge current away from downstream circuitry while maintaining VC ≤ 162 V. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1.0 ps).
Designed for surface-mount automated assembly, the SMCJ100CAHE3_A/I uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, meets MSL level 1 per J-STD-020, and supports operation from –55 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 111 V / 123 V at IT = 1 mA - guaranteed avalanche onset range under standardized test conditions |
| VC @ IPPM | 162 V at 9.3 A - clamped voltage during 10/1000 µs surge, defining worst-case stress on protected IC |
| PPPM | 1500 W - peak transient energy handling capacity, enabling protection against IEC 61000-4-5 Level 4 surges |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves signal integrity and battery life in always-on circuits |
| TJ max. | +150 °C - enables deployment in under-hood automotive environments and high-temperature industrial enclosures |
| RθJA | 75 °C/W - thermal resistance determines required PCB copper area (8.0 mm × 8.0 mm pads recommended) |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink (bidirectional) | Acts as cathode during positive transients; conducts symmetrically in both directions |
| Cathode | Transient current sink (bidirectional) | Acts as anode during negative transients; identical electrical behavior to Anode terminal |
Key Features
| Feature | Design Value |
|---|---|

| UL 497B recognized (QVGQ2) | Meets safety standard for telecom and industrial signal line protectors without external certification burden |
| MSL Level 1, 260 °C peak reflow | Compatible with standard lead-free SMT reflow profiles without moisture sensitivity concerns |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface |
|---|---|
|
Use Scenario: Protecting LIN/CAN bus nodes and microcontroller I/O from load dump and alternator ripple in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bidirectional shunt clamp placed between supply rail and ground, responding within picoseconds to transients. Use Value: Clamps 12 V system surges up to 100 V without forward conduction, preserving logic-level compatibility and preventing latch-up in connected MCUs. |
Use Scenario: Shielding analog front-end inputs of pressure/temperature sensors in factory automation PLC modules. IC Role / Device Role / Timing Role: Standby-mode protector across differential signal pairs (e.g., RS-485) and supply rails. Use Value: Sub-1 µA leakage at 100 V VWM avoids DC offset errors; 162 V VC limits stress on 12-bit ADC input stages during ESD events. |

|
Use Scenario: Safeguarding ADSL/VDSL line drivers and transformers against lightning-induced surges on outdoor copper lines. IC Role / Device Role / Timing Role: Primary surge arrestor mounted at board edge, upstream of isolation transformer and PHY IC. Use Value: 1500 W PPPM rating handles 10/1000 µs surges per ITU-T K.21; bidirectional symmetry matches AC-coupled line signaling. |
Use Scenario: Suppressing inductive kickback from brushed DC motors in smart home appliances (e.g., vacuum cleaners, blenders). IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals to clamp flyback spikes before reaching H-bridge MOSFETs. Use Value: 200 A IFSM rating withstands repetitive commutation surges; 150 °C TJ max supports sealed enclosure thermal environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC100CA | Lower PPPM (600 W), same VWM (100 V), smaller SMA package (DO-214AC) | Limited to lower-energy surges (IEC 61000-4-5 Level 2); unsuitable for automotive load dump | Select when space-constrained and surge threat level is moderate (e.g., consumer USB ports) |
| 1.5KE100CA | Higher VBR (111–123 V), same VC (162 V), axial-leaded DO-15 package | Not SMT-compatible; requires through-hole assembly and larger board area | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SAC100CA and 1.5KE100CA, the SMCJ100CAHE3_A/I delivers higher surge robustness in a compact, AEC-Q101-qualified SMT package - making it optimal for production automotive and industrial control boards requiring reliability, automated assembly, and UL recognition.

FAQ
What is the breakdown voltage range for SMCJ100CAHE3_A/I?
The SMCJ100CAHE3_A/I has a guaranteed breakdown voltage (VBR) range of 111 V to 123 V at IT = 1 mA, measured per ANSI/IEEE C62.35. This defines the voltage threshold at which the device transitions from high-impedance blocking to low-impedance clamping - critical for ensuring reliable activation before protected circuitry exceeds absolute maximum ratings. The SMCJ100CAHE3_A/I maintains this specification across its full operating temperature range.
Is SMCJ100CAHE3_A/I suitable for automotive applications?
Yes, the SMCJ100CAHE3_A/I carries AEC-Q101 qualification (indicated by HE3 suffix), validating its performance under automotive-grade temperature cycling, humidity, mechanical shock, and surge stress tests. It is explicitly rated for use in 12 V and 24 V vehicle subsystems including body control modules, infotainment power supplies, and sensor interfaces - and recognized under UL 497B for surge protector classification. The SMCJ100CAHE3_A/I meets these requirements without derating at +125 °C ambient.
What does the "CA" suffix mean in SMCJ100CAHE3_A/I?
The "CA" suffix in SMCJ100CAHE3_A/I denotes a bidirectional configuration: the device provides symmetrical clamping for both positive and negative voltage transients, with identical VBR, VC, and IPPM characteristics in either polarity. Unlike unidirectional variants (e.g., SMCJ100A), the SMCJ100CAHE3_A/I has no cathode band marking and is used where AC-coupled or differential signal lines require equal protection in both directions - such as RS-485 buses or transformer-isolated power inputs.
How does SMCJ100CAHE3_A/I compare to SMCJ100A in terms of electrical behavior?
The SMCJ100CAHE3_A/I and SMCJ100A share identical VWM (100 V), VBR (111–123 V), VC (162 V), and PPPM (1500 W) ratings, but differ fundamentally in polarity: SMCJ100A is unidirectional (cathode-banded, blocks only reverse voltage), while the SMCJ100CAHE3_A/I is bidirectional (no marking, blocks/clamps in both directions). This makes the SMCJ100CAHE3_A/I appropriate for AC or floating-node applications where polarity reversal is possible - unlike the SMCJ100A, which would conduct destructively under reverse surges.
What is the thermal resistance and recommended PCB layout for SMCJ100CAHE3_A/I?
The SMCJ100CAHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal - as specified in the Vishay datasheet. To maintain safe junction temperatures under repeated surges, designers must implement this minimum pad area and avoid excessive trace length or narrow connections. The SMCJ100CAHE3_A/I's RθJL is 15 °C/W, confirming efficient heat transfer to PCB copper, but thermal performance degrades significantly if pad size falls below the recommended dimensions.
