Product details
Overview
1.5SMC62A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power 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 capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial DC power rails.
For engineers reviewing the 1.5SMC62A-E3/9AT datasheet, 1.5SMC62A-E3/9AT pinout, 1.5SMC62A-E3/9AT application, or 1.5SMC62A-E3/9AT equivalent, key selection criteria include unidirectional polarity, SMC (DO-214AB) package compatibility, clamping performance under repetitive surge conditions, thermal derating above 25 °C, and AEC-Q101 qualification status of related variants.
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, limiting transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repeated stress.
Designed for automated SMT assembly, the device meets J-STD-020 MSL Level 1 (peak reflow ≤ 260 °C), supports 200 A non-repetitive forward surge (8.3 ms half-sine), and exhibits low incremental surge resistance - critical for minimizing voltage overshoot during fast-rising transients like ESD or inductive switching spikes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA test current - defines precise breakdown onset for accurate overvoltage threshold setting |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage rises significantly; sets safe working margin below VBR |
| VC @ IPPM | 85.0 V at 17.6 A - clamping voltage during 1500 W 10/1000 μs surge; determines protected circuit's maximum transient exposure |
| PPPM | 1500 W - peak pulse power handling per standard waveform; enables protection against lightning-induced surges and load dump events |
| IFSM | 200 A - single half-sine surge rating (8.3 ms); supports robustness against automotive load-dump transients |
| TJ max. | +150 °C - maximum junction temperature; allows operation in under-hood automotive environments and enclosed industrial enclosures |
| RθJA | 75 °C/W - thermal resistance junction-to-ambient on standard 8.0 mm × 8.0 mm copper pads; informs board-level thermal design requirements |
Pinout & Package

| MSL Level 1 moisture sensitivity | Allows direct placement without baking; compatible with standard lead-free reflow profiles up to 260 °C peak |
| RoHS-compliant, halogen-free option available | Meets environmental compliance requirements for consumer, industrial, and automotive electronics manufacturing |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin for sensitive ICs |

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 | Lower PPPM (600 W), same VWM/VBR range, SMB package (smaller footprint, higher RθJA) | Best suited for space-constrained consumer electronics where 1500 W rating is not required | Select when board area is limited and surge threat level is moderate (e.g., IEC 61000-4-2 ESD only) |
| 1.5KE62A | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly and higher thermal resistance | Used in legacy designs or prototyping where manual assembly or socketing is acceptable | Choose only if SMT process is unavailable or thermal management via heatsink is preferred over PCB copper area |
Compared with SMBJ64A and 1.5KE62A, the 1.5SMC62A-E3/9AT delivers superior surge robustness in an SMT-optimized package - enabling automated production, tighter thermal coupling to PCB copper, and compliance with automotive AEC-Q101 requirements via HE3/HM3 variants.

FAQ
What is the clamping voltage of the 1.5SMC62A-E3/9AT under maximum rated surge current?
The 1.5SMC62A-E3/9AT has a maximum clamping voltage (VC) of 85.0 V at its rated peak pulse current (IPPM) of 17.6 A, measured using the standardized 10/1000 μs double-exponential surge waveform. This value defines the upper voltage limit imposed on the protected circuit during worst-case transient events and is confirmed in the Vishay 1.5SMC Series datasheet (Document Number: 88303, page 2).
Is the 1.5SMC62A-E3/9AT RoHS-compliant and halogen-free?
Yes, the 1.5SMC62A-E3/9AT carries the "E3" suffix, indicating full RoHS compliance per EU Directive 2011/65/EU. It is not halogen-free; for halogen-free and RoHS-compliant versions, specify the "M3" suffix (e.g., 1.5SMC62A-M3/9AT). Both E3 and M3 variants meet JESD 201 Class 2 whisker resistance requirements.
Does the 1.5SMC62A-E3/9AT have AEC-Q101 qualification?
No, the 1.5SMC62A-E3/9AT itself is not AEC-Q101 qualified. However, the same device in HE3 or HM3 packaging (e.g., 1.5SMC62AHE3_A/I) is AEC-Q101 qualified for automotive applications. The E3/9AT variant is commercial-grade and intended for industrial and consumer use where automotive qualification is not mandated.
What is the thermal resistance of the 1.5SMC62A-E3/9AT, and how does it affect layout?
The 1.5SMC62A-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperatures under sustained power dissipation, PCB layout must provide adequate copper area and minimize trace length between terminals and thermal planes - especially critical in high-duty-cycle surge environments.
How does the unidirectional configuration of the 1.5SMC62A-E3/9AT impact circuit connection?
The 1.5SMC62A-E3/9AT is unidirectional: its cathode is marked by a band on the SMC package and must be connected to the system ground or lower-potential node, while the anode connects to the line being protected. This configuration blocks forward current during normal operation and conducts only during reverse overvoltage events - essential for protecting DC-powered circuits where polarity is fixed.
