Product details
Overview
1.5SMC100CAHE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 100 V standoff voltage (VWM), 114 V minimum breakdown voltage (VBR), 137 V maximum clamping voltage (VC) at 10.9 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive, industrial, and telecom systems to protect MOSFETs, ICs, and sensor interfaces from lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5SMC100CAHE3/57T datasheet, 1.5SMC100CAHE3/57T pinout, 1.5SMC100CAHE3/57T application, or 1.5SMC100CAHE3/57T equivalent, this device delivers AEC-Q101 qualification, low incremental surge resistance, fast sub-nanosecond response time, and MSL Level 1 moisture sensitivity - critical for robust design-in of ESD- and surge-hardened front-end circuits in harsh environments.
Technical Context
The 1.5SMC100CAHE3/57T operates as a bidirectional avalanche diode, symmetrically clamping voltage surges above ±114 V (VBR min) while maintaining ≤±137 V (VC) at its rated 10.9 A IPPM. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive transient stress.
Designed for surface-mount assembly on SMC (DO-214AB) footprint, it supports automated placement and meets J-STD-020 MSL Level 1 (260 °C peak reflow). With a thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads), it sustains 6.5 W steady-state power dissipation at 50 °C ambient when mounted on recommended 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 100 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 114–126 V at 1 mA - Ensures predictable, repeatable avalanche initiation across temperature and unit variation. |
| VC (Clamping Voltage) | 137 V at 10.9 A (10/1000 μs) - Limits downstream voltage stress during surge events to safe levels for protected ICs. |

| TJ max | 150 °C - Enables operation in under-hood automotive and industrial enclosures without derating at full power. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Bidirectional TVS placed at connector entry to clamp ±100 V+ surges before reaching LDOs and microcontrollers. Use Value: Clamps to ≤137 V within nanoseconds, preventing latch-up or gate oxide damage in downstream PMICs and CAN transceivers. |

Use Scenario: Safeguarding PoE-powered switches and base stations against lightning-induced surges on 48 V DC input rails. IC Role / Device Role / Timing Role: Primary surge limiter upstream of DC-DC converters and hot-swap controllers. Use Value: 1500 W rating handles multi-kA induced currents; AEC-Q101 qualification ensures field longevity in outdoor deployments. |
Use Scenario: Front-end protection in universal-input SMPS for TVs, monitors, and set-top boxes exposed to mains-borne surges. IC Role / Device Role / Timing Role: Mounted across bulk capacitor input to absorb line-to-line and line-to-ground transients per IEC 61000-4-5. Use Value: Symmetric clamping eliminates need for dual unidirectional devices; DO-214AB footprint enables compact, cost-effective layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPPM (600 W), same VWM/VBR range, SMB package (smaller footprint, higher RθJA = 110 °C/W). | Best suited for space-constrained, lower-energy applications where 1500 W headroom is unnecessary. | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 2. |
| 1.5KE100CA | Through-hole TO-218 package, identical electrical specs but higher mounting thermal resistance and manual assembly requirement. | Used where legacy through-hole manufacturing or higher mechanical robustness is prioritized over SMT scalability. | Choose only if existing production lines lack SMT capability or require higher vibration resistance than SMC allows. |
Compared with SMBJ100CA and 1.5KE100CA, the 1.5SMC100CAHE3/57T uniquely combines AEC-Q101 qualification, 1500 W surge capacity, and SMC's optimized thermal performance (RθJL = 15 °C/W) - making it the preferred choice for automotive and industrial SMT designs requiring validated reliability and high-power transient handling.

FAQ
What is the clamping voltage of the 1.5SMC100CAHE3/57T at its rated peak pulse current?
The 1.5SMC100CAHE3/57T has a maximum clamping voltage (VC) of 137 V at 10.9 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC and ensures predictable voltage limiting during surge events - critical for protecting downstream components like microcontrollers and interface ICs from overvoltage damage.
Is the 1.5SMC100CAHE3/57T suitable for automotive applications?
Yes, the 1.5SMC100CAHE3/57T is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD verification - making it appropriate for engine control units, body electronics, and ADAS modules where reliability under thermal and electrical stress is essential.
What does the "CA" suffix indicate in 1.5SMC100CAHE3/57T?
The "CA" suffix in 1.5SMC100CAHE3/57T denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., "A"), it has no cathode band marking and functions identically in either orientation, simplifying layout for AC-coupled or floating signal lines.
What is the thermal resistance of the 1.5SMC100CAHE3/57T, and how does it affect PCB layout?
The 1.5SMC100CAHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads (RθJL) of 15 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperatures, PCB layout must follow Vishay's recommended pad dimensions and avoid excessive trace length or narrow copper pours that increase thermal impedance.
How does the 1.5SMC100CAHE3/57T compare to unidirectional TVS diodes in circuit protection design?
The 1.5SMC100CAHE3/57T eliminates polarity dependency, enabling single-device protection of differential signals, AC lines, or ungrounded buses - unlike unidirectional types that require correct orientation and often paired placement. Its bidirectional behavior reduces BOM count and layout complexity while delivering identical clamping performance in both directions, verified across the full -65 °C to +150 °C operating range.
