Product details
Overview
1.5SMC62A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, designed for high-energy surge protection. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at IT = 1.0 mA), 85.0 V maximum clamping voltage (VC) at 17.6 A peak pulse current (IPPM), and 1500 W peak pulse power rating with 10/1000 µs waveform - ideal for safeguarding automotive sensor signal lines against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5SMC62A-E3/57T datasheet, 1.5SMC62A-E3/57T pinout, 1.5SMC62A-E3/57T application, or 1.5SMC62A-E3/57T equivalent, key selection criteria include unidirectional polarity, 53.0 V stand-off voltage (VWM), <1.0 µA reverse leakage at VWM, ±0.104 %/°C temperature coefficient of VBR, and AEC-Q101 qualification eligibility via HE3/HM3 variants.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ) below VWM = 53.0 V, then rapidly avalanches to limit transient overvoltages above VBR. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance (<1 Ω typical), enabling fast response (<1 ns) to ESD and surge events.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Fig. 2; thermal resistance is RθJA = 75 °C/W (on 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W. Polarity is marked by a cathode band, and it complies with J-STD-020 MSL Level 1 (260 °C peak reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at IT = 1.0 mA - defines precise avalanche onset range for reliable clamping threshold |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 85.0 V at 17.6 A - clamped voltage during 10/1000 µs surge, limiting stress on downstream ICs |

Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) in engine control modules from load dump and ISO 7637-2 pulses. IC Role / Device Role: Unidirectional shunt clamp placed between signal line and ground, absorbing transients before they reach the transceiver input. Use Value: Clamps 10/1000 µs surges to ≤85.0 V while maintaining <1 µA leakage at 53.0 V operating voltage - preserving signal integrity and preventing latch-up. |
Use Scenario: Safeguarding 24 V DC digital input channels in programmable logic controllers against field-wiring induced surges and relay contact bounce. IC Role / Device Role: Primary overvoltage clamp on each input channel, coordinated with series current-limiting resistor and optocoupler isolation. Use Value: Withstands repetitive 1500 W pulses at 0.01% duty cycle and maintains stable VBR across -65 °C to +150 °C - ensuring uptime in factory-floor environments. |
| Telecom Line Interface | Consumer Power Adapter Input |
|
Use Scenario: Secondary-side transient suppression on Ethernet PHY power rails (3.3 V/5 V) and RS-485 data lines exposed to ESD and nearby lightning coupling. IC Role / Device Role: Fast-response shunt element placed adjacent to connector, diverting energy before reaching PHY IC or level-shifter. Use Value: Sub-1 ns response time and 85.0 V clamping enable compliance with IEC 61000-4-2 (±15 kV air) and IEC 61000-4-4 (±2 kV EFT) standards. |
Use Scenario: Input-stage surge protection on AC-DC adapter secondary side (12 V output rail) against capacitor discharge and hot-plug transients. IC Role / Device Role: Standoff-rated clamp between regulated output and ground, sized to handle 17.6 A peak without thermal runaway. Use Value: 53.0 V VWM provides 10% margin above 12 V nominal rail; 1500 W rating absorbs multiple 100 ms surges without degradation. |
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 (Digi-Key: SMBJ64AHRCT-ND) | Same SMC package, but lower PPPM = 600 W; VBR = 71.1–78.6 V; VC = 103 V @ 5.8 A | Lower power rating limits use to sub-IEC Level 3 surges; higher clamping voltage increases stress on protected ICs | Select when cost sensitivity outweighs surge robustness, and system-level testing confirms 600 W sufficiency |
| 1.5KE62A (Vishay, DO-201AE) | Through-hole package (DO-201AE); same VBR/VC specs but larger footprint and manual assembly requirement | Not suitable for automated SMT lines; used where board space is unconstrained and legacy through-hole design persists | Choose only for repair/refurbishment of existing through-hole designs or prototyping with breadboard compatibility |
Compared with SMBJ64A and 1.5KE62A, the 1.5SMC62A-E3/57T delivers superior surge immunity (1500 W vs. 600 W or 1500 W with larger footprint), tighter VBR tolerance, and SMT-ready packaging - making it optimal for high-reliability automotive and industrial PCBs requiring automated assembly and AEC-Q101 traceability paths.

FAQ
What is the maximum clamping voltage of the 1.5SMC62A-E3/57T under a 10/1000 µs surge?
The 1.5SMC62A-E3/57T has a maximum clamping voltage (VC) of 85.0 V when subjected to its rated peak pulse current of 17.6 A using the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and reflects worst-case performance under repetitive surge conditions with 0.01% duty cycle. The 1.5SMC62A-E3/57T achieves this with low incremental resistance, minimizing voltage overshoot beyond the clamping plateau.
Is the 1.5SMC62A-E3/57T RoHS-compliant and halogen-free?
Yes, the 1.5SMC62A-E3/57T carries the "E3" suffix, indicating it is RoHS-compliant and meets commercial-grade environmental specifications per Vishay's material categorization (www.vishay.com/doc?99912). It is not halogen-free; for halogen-free and RoHS-compliant versions, specify the "M3" suffix (e.g., 1.5SMC62A-M3/57T). Both E3 and M3 variants use matte tin-plated leads and comply with JESD 201 Class 2 whisker resistance.
Does the 1.5SMC62A-E3/57T have AEC-Q101 qualification?
The base 1.5SMC62A-E3/57T is not AEC-Q101 qualified; however, Vishay offers AEC-Q101-qualified variants under the HE3 (RoHS-compliant + AEC-Q101) and HM3 (halogen-free + RoHS + AEC-Q101) suffixes - for example, 1.5SMC62AHE3_A/H. These require explicit ordering with the HE3 or HM3 designation and revision code (e.g., "A"). The 1.5SMC62A-E3/57T itself is rated for automotive-adjacent use but lacks formal qualification documentation.
What is the thermal resistance and derating behavior of the 1.5SMC62A-E3/57T?
The 1.5SMC62A-E3/57T 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 JEDEC standards. Power derating begins linearly above 25 °C ambient, dropping to zero at +150 °C junction temperature. Derating curves are provided in Figure 2 of the datasheet (Doc. #88303), and junction-to-lead resistance (RθJL) is 15 °C/W - critical for layout decisions involving thermal vias and pad copper thickness.
How does the 1.5SMC62A-E3/57T compare to bidirectional TVS diodes like 1.5SMC62CA?
The 1.5SMC62A-E3/57T is unidirectional and intended for DC-biased lines (e.g., power rails, sensor supplies), whereas 1.5SMC62CA is bidirectional for AC-coupled or floating signal lines (e.g., RS-485, USB D+/D−). The 1.5SMC62A-E3/57T has asymmetric conduction: low forward drop (~3.5 V at 100 A) and high reverse standoff (53.0 V); the CA version exhibits symmetrical clamping in both directions. Using the wrong type risks forward conduction failure or inadequate AC transient suppression.
