Product details
Overview
1.5SMC10CAHE3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 10 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 103 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and AEC-Q101 qualification - making it suitable for automotive ECUs, industrial sensor interfaces, and telecom line protection.
For engineers reviewing the 1.5SMC10CAHE3/57T datasheet, 1.5SMC10CAHE3/57T pinout, 1.5SMC10CAHE3/57T application, or 1.5SMC10CAHE3/57T equivalent, this page delivers verified electrical parameters, package dimensions, real-world clamping behavior, thermal derating curves, and qualified automotive-grade alternatives - all confirmed from Vishay's official 1.5SMC Series document #88303 (Rev. 09-Mar-2026).
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical breakdown (VBR = 10.5–11.6 V at IT = 1.0 mA), clamping (VC = 14.5 V at IPPM = 103 A), and leakage (<10 µA at VWM = 10 V) characteristics in forward and reverse directions. Its glass-passivated junction ensures stable surge response and low incremental resistance under repetitive transients.
Designed for surface-mount implementation in SMC (DO-214AB) package, it delivers MSL Level 1 moisture sensitivity, 260 °C lead-free reflow compatibility, and meets UL 94 V-0 flammability - enabling direct integration into high-reliability automotive and industrial PCBs without conformal coating or mechanical shielding.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 10 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 10.5–11.6 V at 1.0 mA - Voltage at which device enters avalanche breakdown; tight tolerance enables precise protection window alignment. |
| VC (Clamping) | 14.5 V at 103 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; limits stress on downstream ICs/MOSFETs. |
| PPPM | 1500 W - Peak transient power handling capability; supports lightning-induced surges per IEC 61000-4-5 Level 4 (4 kV). |
| IPPM | 103 A - Maximum non-repetitive surge current; validated with 0.31" × 0.31" copper pads per JEDEC standards. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments without thermal throttling. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; informs heatsink-free layout design for short-duration transients. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional - no polarity marking; symmetrical two-terminal construction with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Both terminals function identically; bidirectional conduction allows placement without orientation constraints on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - supports ECU, ADAS camera, and infotainment module deployment. |
| 1500 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5-compliant surges up to 4 kV without degradation; eliminates need for upstream series impedance in many designs. |
| Low clamping ratio (VC/VWM = 1.45) | Minimizes overvoltage exposure to protected ICs - critical for 12 V rail protection where 14.5 V clamping stays within 3.3 V/5 V logic tolerance margins. |
| MSL Level 1, 260 °C reflow compatible | Enables single-pass lead-free assembly without baking or special handling - reduces manufacturing cost and process risk. |
| Glass passivated junction | Ensures stable leakage (<10 µA) and consistent VBR over temperature and lifetime - essential for long-term field reliability. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O pins from load-dump and jump-start transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point to shunt surge energy before reaching sensitive analog front-end or CAN/LIN PHY. Use Value: Clamps to 14.5 V during 103 A surge, preventing latch-up or gate oxide damage in 3.3 V/5 V MCUs while maintaining AEC-Q101 compliance. |
Use Scenario: Safeguarding 4–20 mA current-loop transmitters and RTD input stages against ESD and inductive switching spikes in factory automation PLCs. IC Role / Device Role / Timing Role: Fast-response TVS mounted across signal and return lines to absorb sub-100 ns ESD events and longer 10/1000 µs inductive kicks. Use Value: Sub-1 ns response time and 14.5 V clamping preserve signal integrity of precision 24-bit ADCs without adding series resistance or filtering delay. |
| Telecom Data Line Surge Suppression | Consumer USB Port ESD Protection |
Use Scenario: Shielding RS-485/RS-422 differential pairs in base station backhaul equipment from lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Paired bidirectional TVS devices on A/B lines referenced to ground, leveraging symmetrical clamping to maintain differential mode integrity. Use Value: 1500 W rating handles multi-kV surges per ITU-T K.20/K.21; 10.5–11.6 V VBR ensures no false triggering during normal ±7 V differential swings. |
Use Scenario: Adding secondary-level ESD protection to USB 2.0 data lines (D+/D−) in smart home hubs after primary TVS array. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF typical) bidirectional clamp placed adjacent to USB connector to suppress ±15 kV contact discharge per IEC 61000-4-2. Use Value: 14.5 V clamping prevents damage to USB PHY transceivers rated for 5.5 V absolute maximum, while 10 V VWM avoids signal attenuation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W) | Limited to consumer-grade, low-energy surges (IEC 61000-4-2 only); not AEC-Q101 qualified | Select when space-constrained and automotive qualification is unnecessary; verify thermal margin for >100 A surges. |
| 1.5KE10CA | Same VWM (10 V), same PPPM (1500 W), axial DO-201 package (larger, through-hole) | Requires PCB mounting holes and wave soldering; unsuitable for automated SMT lines | Choose only for legacy board redesigns or prototyping where SMC footprint is unavailable; avoid for new automotive designs. |
Compared with SMAJ10CA and 1.5KE10CA, the 1.5SMC10CAHE3/57T uniquely combines AEC-Q101 qualification, SMC surface-mount compatibility, and full 1500 W surge capacity - enabling drop-in use in production automotive modules without layout or reliability compromise.

Yes - the 1.5SMC10CAHE3/57T carries AEC-Q101 qualification (indicated by the "HE3" suffix) and is explicitly listed in Vishay's automotive ordering codes. It meets temperature cycling, humidity, and surge robustness requirements for under-hood and cabin ECU applications per Rev. 09-Mar-2026 documentation.
Does the 1.5SMC10CAHE3/57T have polarity markings on the package?
No - the 1.5SMC10CAHE3/57T is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction allows unrestricted orientation during automated placement, simplifying PCB layout and reducing assembly errors.
What is the maximum junction temperature rating for the 1.5SMC10CAHE3/57T?
The 1.5SMC10CAHE3/57T has a maximum junction temperature (TJ) of +150 °C, as specified in the "Maximum Ratings" table of Vishay document #88303. This enables reliable operation in high-ambient environments such as engine control modules and industrial motor drives.
