Product details
Overview
1.5SMC7.5CAHE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on signal or power lines. It features a 7.13 V minimum breakdown voltage (VBR), 6.40 V standoff voltage (VWM), 11.3 V maximum clamping voltage (VC) at 133 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the 1.5SMC7.5CAHE3/57T datasheet, 1.5SMC7.5CAHE3/57T pinout, 1.5SMC7.5CAHE3/57T application, or 1.5SMC7.5CAHE3/57T equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), junction temperature limit (TJ = 150 °C), and bidirectional clamping behavior critical for ESD and lightning surge protection design.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance (±5% typical), low incremental surge resistance, and fast response time (<1 ns) to transient events.
Rated for 1500 W peak pulse power under 10/1000 µs waveform with 0.01% duty cycle, it sustains repetitive surges when mounted on 8.0 mm × 8.0 mm copper pads. The device meets MSL Level 1 per J-STD-020 and is AEC-Q101 qualified - confirming suitability for automotive under-hood and infotainment applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.40 V - Maximum continuous reverse operating voltage before leakage exceeds 500 µA; defines safe DC bias margin. |
| VBR (min) | 7.13 V at 10 mA - Minimum voltage at which device enters avalanche conduction; ensures reliable turn-on during overvoltage. |
| VC | 11.3 V at 133 A - Clamped voltage seen by protected circuit during 10/1000 µs surge; limits stress on downstream ICs. |
| PPPM | 1500 W - Peak transient power handling capability; determines survivability against lightning-induced surges. |
| IPPM | 133 A - Corresponding peak pulse current at VC; used to size PCB trace width and layout for surge path. |
| TJ max | +150 °C - Maximum junction temperature; sets thermal derating envelope for high-ambient environments. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; informs heatsinking requirements for sustained power dissipation. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional - no polarity marking; symmetrical terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Either terminal accepts surge current in either direction; no cathode band marking required for bidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock per JESD22 standards. |

| 1500 W peak pulse power | Supports IEC 61000-4-5 Level 4 (4 kV surge) compliance when properly laid out with low-inductance paths. |
| MSL Level 1 | Enables standard reflow soldering without pre-baking; compatible with automated SMT assembly at 260 °C peak. |
| Low clamping ratio (VC/VBR ≈ 1.59) | Minimizes overvoltage exposure to protected ICs - critical for 5 V and 3.3 V logic interface protection. |
Applications
| Automotive Sensor Interface Protection | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and ESD in engine control units. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and ground, absorbing transients before they reach the IC's ESD structure. Use Value: Maintains signal integrity during 10/1000 µs surges up to 133 A while limiting clamped voltage to 11.3 V - within absolute maximum ratings of most automotive-grade microcontrollers. |
Use Scenario: Safeguarding 24 V digital input channels on programmable logic controllers exposed to inductive switching noise from solenoids and relays. IC Role / Device Role / Timing Role: Standoff voltage (6.40 V) blocks normal 24 V DC operation, but triggers instantly during >7.13 V transients to shunt energy to ground. Use Value: Enables robust field-side immunity per IEC 61000-4-4 (electrical fast transients) and IEC 61000-4-5 (surge) without adding series impedance or signal delay. |
| Consumer Appliance Motor Drive Protection | Telecom Power Supply Input Protection |
Use Scenario: Shielding microcontroller GPIOs and gate drivers in smart home appliances (e.g., washing machine motor control boards) from back-EMF spikes. IC Role / Device Role / Timing Role: Fast-response TVS placed across motor driver outputs or MCU input pins to clamp sub-10 ns ESD events and slower inductive spikes. Use Value: Glass-passivated junction ensures consistent clamping performance over 10+ years of thermal cycling - critical for white goods lifetime reliability. |
Use Scenario: Front-end protection for AC/DC power supplies in VoIP phones and base stations subjected to lightning-induced surges on primary-side inputs. IC Role / Device Role / Timing Role: First-line defense parallel to bulk capacitor, diverting surge current away from rectifier bridge and controller IC. Use Value: 1500 W rating supports coordination with upstream fuses or PTCs for selective protection architecture compliant with UL 60950-1 Annex G. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | Lower peak power (600 W), smaller SMB package (DO-214AA), VC = 12.0 V at 50 A. | Limited to lower-energy transients; not suitable for IEC 61000-4-5 Level 4. | Select when board space is constrained and surge threat level is ≤ Level 2. |
| 1.5KE7.5CA | Through-hole TO-204AE (DO-41), same VBR/VC, but higher RθJA (100 °C/W) and no AEC-Q101 qualification. | Not automotive-qualified; requires manual insertion or wave soldering. | Choose only for legacy through-hole designs or non-automotive cost-sensitive applications. |
Compared with SMBJ7.0CA and 1.5KE7.5CA, the 1.5SMC7.5CAHE3/57T delivers higher surge robustness (1500 W vs. 600 W or 1500 W with inferior thermal performance), AEC-Q101 validation, and SMC package compatibility with high-volume SMT lines - making it the preferred choice for new automotive and industrial designs requiring field reliability.

The 1.5SMC7.5CAHE3/57T has a maximum clamping voltage (VC) of 11.3 V at 133 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet (Document Number: 88303, Rev. 09-Mar-2026) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 1.5SMC7.5CAHE3/57T AEC-Q101 qualified?
Yes, the 1.5SMC7.5CAHE3/57T is AEC-Q101 qualified. The "HE3" suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified construction, validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces per the Vishay 1.5SMC Series datasheet.
What does the "CA" suffix mean in 1.5SMC7.5CAHE3/57T?
The "CA" suffix in 1.5SMC7.5CAHE3/57T indicates 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 marking and functions identically in either orientation.
What is the standoff voltage (VWM) of the 1.5SMC7.5CAHE3/57T?
The standoff voltage (VWM) of the 1.5SMC7.5CAHE3/57T is 6.40 V. This is the maximum continuous reverse working voltage the device can block without exceeding 500 µA leakage current, ensuring compatibility with 5 V logic systems while maintaining sufficient margin above nominal rail voltage.
What package type does the 1.5SMC7.5CAHE3/57T use?
The 1.5SMC7.5CAHE3/57T uses the SMC (DO-214AB) surface-mount package - a low-profile, robust outline measuring 7.11 mm × 6.22 mm × 2.62 mm with matte tin-plated leads. It is optimized for automated placement and meets UL 94 V-0 flammability rating per Vishay's mechanical data.
