Product details
Overview
1.5SMC62AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in power rails and signal lines. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at IT = 1.0 mA), 53.0 V stand-off voltage (VWM), 85.0 V maximum clamping voltage (VC) at 17.6 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial sensor interfaces, and DC power input stages.
For engineers reviewing the 1.5SMC62AHE3_A/H datasheet, 1.5SMC62AHE3_A/H pinout, 1.5SMC62AHE3_A/H application, or 1.5SMC62AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, thermal resistance (RθJA = 75 °C/W), and clamping performance under repetitive surge conditions.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (53.0 V), it transitions from high-impedance blocking to low-impedance conduction, diverting transient energy to ground while limiting downstream voltage to ≤85.0 V. Its glass-passivated junction ensures stable breakdown and fast response (<1 ns).
The device is rated for 200 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports operation from −65 °C to +150 °C, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for automated SMT assembly without moisture sensitivity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - defines precise breakdown onset tolerance for reliable triggering above normal operating voltage |
| VWM | 53.0 V - maximum continuous reverse voltage before leakage exceeds 1.0 µA; sets safe operating margin below VBR |
| VC @ IPPM | 85.0 V at 17.6 A - clamping voltage during 1500 W transient; determines maximum stress on protected IC or MOSFET |
| PPPM | 1500 W (10/1000 µs) - peak surge handling capacity; validates robustness against lightning-induced or inductive-switching transients |
| IFSM | 200 A (8.3 ms half-sine) - surge current endurance in unidirectional mode; supports protection of high-current power inputs |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance; informs PCB copper pad sizing (0.31" × 0.31") for thermal derating |
| AEC-Q101 | Qualified - confirms reliability for automotive applications including engine control, body electronics, and ADAS sensor power rails |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic case with matte tin-plated leads; polarity indicated by cathode band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to protected circuit's lower-potential node (e.g., GND or return path) | Provides low-VF path during surge conduction; must be routed with minimal inductance to avoid voltage overshoot |
| Cathode | Current exit terminal in forward bias; connected to protected circuit's higher-potential node (e.g., VIN or signal line) | Defines unidirectional clamping direction; band marking enables automated optical inspection and correct placement |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables single-device protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 12 V/24 V automotive power nets |
| Glass-passivated junction | Ensures long-term stability of VBR and low leakage (<1 µA at VWM) across temperature and lifetime |
| MSL Level 1, 260 °C peak | Eliminates pre-bake requirement for standard lead-free reflow, reducing manufacturing cost and cycle time |
| AEC-Q101 qualification | Validates performance under automotive-grade temperature cycling, humidity, and mechanical shock per JESD47 |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving system-level immunity |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamping |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A-E3/52T (Vishay) | Lower PPPM (600 W), same VWM/VBR range, SMB package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for ISO 16750-2 load dump but adequate for IEC 61000-4-2/4-4 | Select when board space is constrained and surge energy does not exceed 600 W; verify thermal margin with smaller pad layout |
| 1.5KE62A (ON Semiconductor) | Through-hole DO-201 package, identical VBR/VC specs, same 1500 W rating, no AEC-Q101 qualification | Requires wave soldering or hand assembly; lacks automotive reliability validation and MSL Level 1 compliance | Choose for legacy through-hole designs or cost-sensitive non-automotive applications where reflow compatibility is not required |
Compared with SMBJ64A-E3/52T and 1.5KE62A, the 1.5SMC62AHE3_A/H uniquely combines AEC-Q101 qualification, SMC surface-mount compatibility, and full 1500 W surge capability - making it the only option qualified for new automotive SMT designs requiring both high energy handling and production reliability.

FAQ
What is the clamping voltage of the 1.5SMC62AHE3_A/H under maximum surge conditions?
The 1.5SMC62AHE3_A/H exhibits a maximum clamping voltage (VC) of 85.0 V at its rated peak pulse current of 17.6 A (10/1000 µs waveform). This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The 1.5SMC62AHE3_A/H maintains this clamping performance consistently across its qualified temperature range (−65 °C to +150 °C) and after multiple surge cycles.
Is the 1.5SMC62AHE3_A/H suitable for automotive applications?
Yes, the 1.5SMC62AHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix and revision-coded "_A/H" ordering format. It meets requirements for temperature cycling, humidity testing, and mechanical shock per JESD47, and is deployed in engine control units, body control modules, and ADAS sensor power supplies. The 1.5SMC62AHE3_A/H also complies with MSL Level 1 for lead-free reflow, supporting modern automotive manufacturing processes.
What is the standoff voltage (VWM) of the 1.5SMC62AHE3_A/H, and why does it matter?
The 1.5SMC62AHE3_A/H has a maximum reverse standoff voltage (VWM) of 53.0 V, which is the highest DC or continuous AC voltage the device can block without exceeding 1.0 µA leakage current. This parameter ensures the 1.5SMC62AHE3_A/H remains non-conductive during normal operation - for example, on a nominal 48 V telecom line or 36 V automotive system - while still triggering reliably above 58.9 V during transients. Maintaining sufficient margin between VWM and system operating voltage prevents false triggering and power loss.
How does the 1.5SMC62AHE3_A/H differ from bidirectional TVS diodes like 1.5SMC62CA?
The 1.5SMC62AHE3_A/H is unidirectional and features polarity marking (cathode band); it conducts only when cathode is positive relative to anode, making it ideal for DC power rail protection. In contrast, 1.5SMC62CA is bidirectional with symmetrical clamping in both directions and no polarity marking - suited for AC lines or differential signal pairs. The 1.5SMC62AHE3_A/H offers lower leakage at VWM and higher IFSM (200 A vs. none specified for bidirectional), but cannot protect AC-coupled signals without external biasing.
What package type does the 1.5SMC62AHE3_A/H use, and what are its mounting requirements?
The 1.5SMC62AHE3_A/H uses the SMC (DO-214AB) surface-mount package - measuring 7.75 mm × 6.22 mm × 2.62 mm - with matte tin-plated leads compliant with J-STD-002 and JESD22-B102. Recommended mounting uses 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal to achieve the specified thermal resistance (RθJA = 75 °C/W) and 1500 W pulse rating. The 1.5SMC62AHE3_A/H is MSL Level 1, allowing direct placement into standard lead-free reflow profiles peaking at 260 °C.
