Product details
Overview
1.5SMC62CAHE3/57T 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 62 V standoff voltage (VWM), 68.9–75.1 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 μs), clamping voltage of 102 V at 17.6 A, and operates across –65 °C to +150 °C. It is used in automotive sensor interfaces and industrial I/O protection where fast response and high surge immunity are critical.
For engineers reviewing the 1.5SMC62CAHE3/57T datasheet, 1.5SMC62CAHE3/57T pinout, 1.5SMC62CAHE3/57T application, or 1.5SMC62CAHE3/57T equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SMC (DO-214AB) package details, clamping performance under standardized surge waveforms, and direct alternative part comparisons for ESD and lightning transient mitigation.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its symmetrical clamping behavior ensures identical protection in both polarities, eliminating polarity concerns in AC-coupled or floating signal paths.
Rated for 1500 W peak pulse power per 10/1000 μs waveform with 0.01% duty cycle, it sustains repetitive transients when mounted on 8.0 mm × 8.0 mm copper pads. Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads), supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 62 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 68.9–75.1 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 102 V at 17.6 A - Peak voltage seen by protected circuit during 1500 W surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 1500 W - Surge energy handling capability per 10/1000 μs waveform; meets IEC 61000-4-5 Level 4 requirements. |
| ID (Reverse Leakage) | 1 μA max at 62 V - Minimal DC leakage at rated standoff, preserving signal integrity and power efficiency. |
| TJ Range | –65 °C to +150 °C - Full automotive-grade operating and storage temperature range; qualified per AEC-Q101. |
| Package | SMC (DO-214AB) - Surface-mount package with 7.75 mm × 6.22 mm footprint; supports automated placement and reflow. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; common node in bidirectional configuration | Not marked on device; symmetric terminals enable polarity-agnostic placement on PCB. |
| Cathode | Current exit terminal in forward bias; common node in bidirectional configuration | No band marking - bidirectional operation eliminates cathode/anode distinction in layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions - simplifies design for AC, differential, or floating bus protection without polarity constraints. |
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
| 1500 W surge rating | Withstands IEC 61000-4-5 10/1000 μs surges up to 17.6 A - protects against lightning-induced transients and inductive switching spikes. |
| Low clamping ratio (VC/VBR ≈ 1.42) | High clamping efficiency minimizes voltage overshoot during fast transients - reduces risk of latch-up or gate oxide damage in MOSFETs/ICs. |
| MSL Level 1 moisture sensitivity | Zero bake requirement before reflow - enables direct placement into high-volume SMT lines without dry-pack handling. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower PPPM (600 W), same 64 V VWM, SMB package (smaller footprint, higher thermal resistance) | Best suited for space-constrained consumer electronics with lower surge exposure (IEC 61000-4-2 only) | Select when board area is limited and peak surge current ≤10 A is sufficient. |
| 1.5KE62CA | Higher leakage (5 μA), axial leaded DO-201 package, same VWM/VC but slower response due to parasitic inductance | Used in legacy through-hole designs or prototyping; not suitable for high-frequency or automated SMT lines | Choose only for manual assembly or cost-sensitive non-automated production where reflow compatibility is not required. |
Compared with 1.5SMC62CAHE3/57T, SMBJ64CA offers smaller size but reduced surge capacity, while 1.5KE62CA provides identical clamping performance in through-hole form but lacks AEC-Q101 qualification and SMT process support - making 1.5SMC62CAHE3/57T the optimal choice for automotive and industrial SMT applications requiring 1500 W robustness and automotive reliability.

FAQ
What is the clamping voltage of the 1.5SMC62CAHE3/57T under a 1500 W surge?
The 1.5SMC62CAHE3/57T clamps to a maximum of 102 V at 17.6 A, corresponding to the standardized 10/1000 μs waveform delivering 1500 W peak pulse power. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per JEDEC standards and represents the worst-case voltage imposed on protected circuitry during full-rated surge conditions.
Is the 1.5SMC62CAHE3/57T suitable for automotive applications?
Yes, the 1.5SMC62CAHE3/57T carries AEC-Q101 qualification (indicated by the "HE3" suffix) and is explicitly rated for automotive use in engine control units, body electronics, and ADAS sensor interfaces. Its –65 °C to +150 °C operating range, MSL Level 1 reflow compatibility, and validated surge performance meet stringent automotive reliability requirements.
How does the bidirectional design of the 1.5SMC62CAHE3/57T affect PCB layout?
The 1.5SMC62CAHE3/57T has no polarity marking and identical electrical behavior in both directions, so PCB layout requires no orientation alignment. This eliminates risk of misplacement during automated assembly and simplifies routing for AC-coupled, differential, or floating signal lines - unlike unidirectional TVS diodes that require strict anode/cathode placement.
What is the maximum reverse leakage current for the 1.5SMC62CAHE3/57T at its rated standoff voltage?
The 1.5SMC62CAHE3/57T exhibits a maximum reverse leakage current of 1 μA at 62 V (VWM), measured at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor circuits and minimizes standby power loss in battery-powered systems without compromising clamping responsiveness.
Does the 1.5SMC62CAHE3/57T require derating at elevated ambient temperatures?
Yes, the 1.5SMC62CAHE3/57T must be derated above 25 °C ambient per Figure 2 in the Vishay datasheet (Document Number: 88303). At 85 °C ambient, its 1500 W peak pulse power rating drops to approximately 750 W - a 50% reduction - due to thermal limitations. Designers must verify clamping performance under worst-case thermal conditions using the published derating curve.
