Product details
Overview
1.5SMC62 from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 55.8–68.2 V breakdown voltage (VBR), 50.2 V working stand-off voltage (VWM), 89.0 V maximum clamping voltage (VC) at 17 A peak pulse current, and 1500 W peak pulse power rating per 10/1000 µs waveform - deployed in telecom front-ends, industrial I/O modules, and automotive body control units.
For engineers reviewing the 1.5SMC62 datasheet, 1.5SMC62 pinout, 1.5SMC62 application, or 1.5SMC62 equivalent, key selection criteria include clamping performance under ISO 7637-2 Pulse 1/2a/2b/3a/3b, junction-to-ambient thermal resistance (50 °C/W), unidirectional polarity marking, and DO-214AB (SMC) package compatibility with automated SMT placement.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR, it avalanches rapidly (<1.0 ps response) to divert surge current away from downstream ICs. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and long-term reliability under repeated transients.
Thermally, it sustains 150 °C maximum junction temperature with 50 °C/W RθJA and 15 °C/W RθJC, enabling use in compact, convection-cooled PCB layouts. The DO-214AB case meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 55.8 V / 68.2 V - defines minimum and maximum voltage at which avalanche conduction begins reliably at 1 mA test current |
| VWM | 50.2 V - maximum continuous DC or RMS voltage the device blocks without significant leakage |
| VC @ IPPM | 89.0 V at 17 A - clamping voltage during 10/1000 µs surge, limiting stress on protected circuitry |
| PPK | 1500 W - peak pulse power dissipation capability for non-repetitive transients per Fig.5 |
| IR @ VWM | <1 µA - ultra-low reverse leakage ensures minimal standby power loss and signal integrity |
| TJ max | +150 °C - maximum allowable junction temperature supports operation in high-ambient industrial environments |
| Package | DO-214AB (SMC) - industry-standard surface-mount outline with cathode band marking and 0.210 g mass |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band on unidirectional variants. Compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage rail; forms current return path during clamping |
| Cathode | High-side surge input terminal | Connected to protected line; avalanche conduction initiates here when VAK exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and low IR drift across temperature and lifetime |
| Fast response time | <1.0 ps - enables suppression of ESD and fast-rising lightning-induced transients before IC damage occurs |
| ISO 7637-2 compliance | Validated for Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) in automotive and industrial systems |
| Moisture sensitivity level | MSL Level 1 (per J-STD-020) - allows unlimited floor life and standard reflow without baking |
| Halogen-free construction | Complies with IEC 61249-2-21 - supports RoHS-compliant and environmentally regulated end equipment |
Applications
| Telecom Line Interface Protection | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protecting RS-485 transceivers and Ethernet PHYs against induced surges from nearby AC wiring or antenna coupling in base stations and access points. IC Role / Device Role: Unidirectional shunt TVS placed between data line and chassis ground, clamping common-mode transients before they reach the transceiver ESD structure. Use Value: Limits VC to 89.0 V during 17 A 10/1000 µs surge, keeping stress below the 100 V absolute maximum rating of typical RS-485 drivers. | Use Scenario: Safeguarding 24 V DC digital input channels in programmable logic controllers exposed to relay coil flyback and field-wiring faults. IC Role / Device Role: Standoff-rated TVS connected between input terminal and 0 V rail, absorbing repetitive 100–500 V, 100 ns–1 µs transients from inductive switching. Use Value: With VWM = 50.2 V and VC = 89.0 V, it remains inactive during normal 24 V operation while clamping fault voltages well below the 100 V input stage limit of industrial-grade optocouplers. |
| Automotive Body Control Module (BCM) | Consumer Appliance Power Supply Inrush Suppression |
Use Scenario: Protecting LIN bus transceivers and sensor inputs in BCMs subjected to battery disconnect/load dump events per ISO 7637-2 Pulse 2b and Pulse 5a. IC Role / Device Role: Unidirectional TVS on 12 V supply rail and LIN signal line, providing coordinated clamping with upstream fuses and downstream L-C filters. Use Value: 1500 W peak power rating and 50.2 V VWM allow reliable hold-off of nominal 13.5–14.5 V system voltage while clamping 100 V+ pulses to ≤89.0 V within <1 ps. | Use Scenario: Suppressing turn-on surges and MOSFET gate drive spikes in switched-mode power supplies of washing machines and HVAC controllers. IC Role / Device Role: TVS placed across primary-side snubber networks or secondary-side rectifier outputs to clamp voltage overshoot during MOSFET switching transitions. Use Value: Low 1 µA leakage at 50.2 V prevents measurable standby current increase, while 89.0 V clamping protects 100 V-rated output capacitors and synchronous rectifiers. |
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 (Bourns) | 64 V VBR range (57.6–64.0 V), 64 V VWM, 1000 W PPK, DO-214AA (SMB) package | Lower peak power and smaller footprint; suitable where space is constrained but surge energy is moderate | Select SMBJ64A only if board layout uses SMB pads and system-level surge energy does not exceed 1000 W |
| 1.5KE62A (ON Semiconductor) | 62 V VBR (55.8–68.2 V), 50.2 V VWM, 1500 W PPK, axial DO-15 package | Through-hole mounting required; higher thermal resistance (RθJA ≈ 60 °C/W) limits high-density or high-ambient use | Choose 1.5KE62A only for legacy through-hole designs or prototyping where rework flexibility outweighs SMT efficiency |
Compared with SMBJ64A and 1.5KE62A, the 1.5SMC62 delivers identical voltage ratings and superior 1500 W surge handling in a surface-mount DO-214AB package optimized for automated assembly, thermal performance (50 °C/W RθJA), and moisture resilience (MSL Level 1).

FAQ
What is the breakdown voltage range of the 1.5SMC62?
The 1.5SMC62 has a guaranteed breakdown voltage (VBR) range of 55.8 V to 68.2 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range reflects manufacturing tolerance and ensures reliable avalanche initiation across all qualified units of the 1.5SMC62 under standard test conditions.
Is the 1.5SMC62 unidirectional or bidirectional?
1.5SMC62 is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix. It conducts only during reverse-biased overvoltage events - anode grounded, cathode connected to the protected line - and blocks forward voltage up to 3.5 V at 50 A, as specified for this voltage grade.
What is the maximum clamping voltage of the 1.5SMC62 during a surge event?
The 1.5SMC62 exhibits a maximum clamping voltage (VC) of 89.0 V at 17 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per Figure 5 in the datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case transient conditions.
Does the 1.5SMC62 meet automotive surge immunity standards?
Yes, the 1.5SMC62 meets ISO 7637-2 requirements for Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling), making it suitable for automotive body electronics, infotainment interfaces, and sensor signal conditioning where certified transient immunity is mandatory.
