Product details
Overview
1.5SMC62CAH from Taiwan Semiconductor is a bidirectional 1500W surface-mount transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 62V, clamping voltage of 85.0V at 18A peak pulse current, and working stand-off voltage of 53.0V. It features glass-passivated junction, AEC-Q101 qualification, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and ESD protection in power supply rails.
For engineers reviewing the 1.5SMC62CAH datasheet, 1.5SMC62CAH pinout, 1.5SMC62CAH application, or 1.5SMC62CAH equivalent, this device is selected for robust overvoltage immunity in DC power interfaces where fast response (<1.0 ps), low leakage (<1 µA @ 53.0V), and DO-214AB package compatibility are critical design requirements.
Technical Context
The 1.5SMC62CAH operates as a bidirectional avalanche-clamping TVS diode, designed to shunt transient energy away from sensitive downstream circuitry by entering breakdown symmetrically in both polarities. Its glass-passivated chip junction ensures stable VBR tolerance (58.9–65.1 V) and low temperature coefficient (0.104 %/°C).
It delivers 1500W peak pulse power (10/1000 µs waveform), with thermal resistance RθJA = 50 °C/W and RθJC = 15 °C/W, enabling reliable operation up to TJ = +150 °C in compact SMC layouts. The device complies with JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V - Ensures consistent avalanche initiation across production lots and temperature range |
| VWM | 53.0 V - Maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 85.0 V @ 18 A - Clamping voltage during 10/1000 µs surge; limits stress on protected ICs |
| IR @ VWM | <1 µA - Negligible standby power loss and signal integrity impact in high-impedance circuits |
| PPK | 1500 W - Handles automotive load dump (ISO 7637-2 Pulse 5a) and lightning-induced surges |
| TJ max | +150 °C - Supports under-hood and industrial ambient conditions without derating |
| Package | DO-214AB (SMC) - Standardized 7.11 × 6.22 mm surface-mount footprint with matte tin leads |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with two coplanar terminals; polarity indicated by cathode band (bidirectional symmetry means no functional anode/cathode marking required for 1.5SMC62CAH).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode (for unidirectional reference) | Common connection point; bidirectional operation renders polarity irrelevant in system-level placement |
| Terminal 2 | Cathode (for unidirectional reference) | Same electrical node as Terminal 1 under reverse bias; symmetrical clamping in both directions |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| ISO 7637-2 compliance | Withstands Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (capacitive coupling) waveforms |
| Glass-passivated junction | Stable VBR drift <±5% over lifetime; immune to humidity-induced parameter shift |
| Fast response time | <1.0 ps - Clamps transients before propagation into protected ICs (e.g., CAN transceivers, MCU I/O) |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU Directive 2011/65/EU; suitable for green manufacturing |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: 12 V battery-fed ECUs exposed to load dump (up to 35 V sustained, 60+ V spikes) and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converters and microcontroller power inputs. Use Value: Limits rail voltage to ≤85.0 V during 1500 W transients, preventing damage to 3.3 V/5 V logic and analog front-ends. |
Use Scenario: 24 V digital input modules receiving signals from field sensors subject to inductive kickback and ESD. IC Role / Device Role / Timing Role: Bidirectional transient suppressor on dry-contact or 2-wire sensor lines interfacing to optocouplers or Schmitt triggers. Use Value: Blocks ±85.0 V clamped surges while maintaining <1 µA leakage at 24 V nominal, preserving input threshold accuracy. |
| Telecom DC Feeder Protection | Consumer USB-C Power Delivery Line |
Use Scenario: -48 V telecom power feeds vulnerable to lightning-induced common-mode surges on long outdoor cable runs. IC Role / Device Role / Timing Role: Paired differential-mode TVS on positive/negative rails relative to ground, referenced to chassis earth. Use Value: Absorbs 10/1000 µs surges up to 18 A without degradation, meeting GR-1089-CORE Level 3 immunity requirements. |
Use Scenario: VBUS line in USB-C PD 3.0 designs supporting 20 V / 5 A, requiring robust ESD (IEC 61000-4-2 ±15 kV) and surge resilience. IC Role / Device Role / Timing Role: Secondary protection stage after integrated ESD array, handling higher-energy events beyond silicon-limited clamping. Use Value: Clamps 8 kV contact ESD to <85.0 V within <1 ps, protecting USB PD controller and port power switches from latch-up or gate oxide rupture. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower PPK = 600 W; VC = 103 V @ 5.8 A; SMB package (smaller footprint, higher RθJA) | Suitable for lower-energy transients (e.g., IEC 61000-4-5 Level 3); not rated for ISO 7637-2 Pulse 5a | Select when space-constrained layout prioritizes 4.5 × 3.9 mm SMB over SMC and peak surge energy is ≤600 W. |
| 1.5KE62CA | Through-hole TO-204AA (DO-41); same VBR/VC specs but slower thermal response and no AEC-Q101 qualification | Used in legacy industrial power supplies where automated SMT is not required and automotive qualification is unnecessary | Choose only for through-hole prototyping or cost-sensitive non-automotive applications where reflow compatibility is not needed. |
Compared with SMBJ64CA and 1.5KE62CA, the 1.5SMC62CAH provides superior surge handling (1500 W vs. 600 W or unspecified), AEC-Q101 validation for automotive use, and optimized thermal performance in SMT production-making it the preferred choice for high-reliability 12/24 V DC systems requiring full ISO 7637-2 immunity.

FAQ
What is the clamping voltage of the 1.5SMC62CAH under standard 10/1000 µs surge conditions?
The 1.5SMC62CAH has a maximum clamping voltage (VC) of 85.0 V at 18 A peak pulse current (IPPM) under the standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed across temperature and process variation, ensuring predictable protection margin for downstream 5 V or 3.3 V ICs when used with appropriate series impedance.
Is the 1.5SMC62CAH suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the 1.5SMC62CAH is explicitly AEC-Q101 qualified per the manufacturer's documentation and undergoes stress testing including HTGB, H3TRB, and temperature cycling. It also meets ISO 7637-2 Pulse 1/2a/2b/3a/3b, making it certified for use in engine control units, body electronics, and ADAS power domains.
How does the bidirectional configuration of the 1.5SMC62CAH affect its PCB layout compared to unidirectional TVS diodes?
The 1.5SMC62CAH has symmetrical electrical behavior in both polarities, eliminating orientation constraints during placement. Unlike unidirectional TVS diodes that require strict cathode alignment, the 1.5SMC62CAH can be mounted in either direction on the PCB-reducing assembly errors and simplifying automated pick-and-place programming for DO-214AB footprints.
What is the maximum steady-state power dissipation rating for the 1.5SMC62CAH at 25°C ambient?
The 1.5SMC62CAH has a steady-state power dissipation (PD) rating of 6.5 W at TA = 25°C. This value reflects continuous DC or low-frequency power handling capability-not surge capability-and must be derated linearly above 25°C using the specified RθJA = 50 °C/W thermal resistance.
Does the 1.5SMC62CAH meet halogen-free and RoHS requirements for environmentally regulated markets?
Yes, the 1.5SMC62CAH is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and the matte tin-plated leads satisfy J-STD-002 solderability standards without lead or cadmium content.
