Product details
Overview
1.5SMC13H from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 1500W peak pulse power, 11.7–14.3V breakdown voltage (VBR), and 19.0V maximum clamping voltage (VC) at 82A peak impulse current. It protects automotive and industrial power rails against ESD, lightning-induced surges, and load-switching transients.
For engineers reviewing the 1.5SMC13H datasheet, 1.5SMC13H pinout, 1.5SMC13H application, or 1.5SMC13H equivalent, this device delivers AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, sub-1ps response time, <1µA leakage above 10.5V, and glass-passivated junction reliability in high-volume SMT deployments.
Technical Context
The 1.5SMC13H operates as a unidirectional avalanche diode with a single-die construction optimized for fast clamping of transient overvoltages on DC power lines. Its VWM = 10.5V ensures compatibility with 12V nominal systems while maintaining low leakage (<1µA) at stand-off.
Thermal performance is defined by RθJA = 50°C/W and RθJC = 15°C/W, supporting sustained operation up to TJ = +150°C. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements for robust reflow processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.7V / 14.3V - Ensures reliable avalanche initiation within 10% tolerance band at 1mA test current |
| VWM | 10.5V - Maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 19.0V at 82A - Clamps transients to safe levels for downstream 20V-rated ICs and MOSFETs |
| PPK | 1500W - Handles 10/1000µs surge waveforms per IEC 61000-4-5 without degradation |
| IR @ VWM | <1µA - Minimizes standby power loss in battery-backed or energy-sensitive circuits |
| TJ max | +150°C - Enables use in under-hood automotive environments and enclosed industrial enclosures |
| Package | DO-214AB (SMC) - Standardized 7.11 × 6.22 mm surface-mount footprint compatible with automated placement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | 600W rating, SMB package (smaller footprint), 14.4–15.9V VBR, 21.5V VC @ 28.1A | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 1 or 5A+ surge currents | Select when board space is constrained and peak surge energy remains below 600W |
| 1.5KE13A | Through-hole TO-204AA (DO-41), 1500W, 14.4–15.9V VBR, 21.5V VC @ 70A | Requires manual or wave-solder assembly; lacks AEC-Q101 and ISO 7637-2 validation | Choose only for non-automotive prototyping or legacy through-hole designs where SMT is unavailable |
Compared with SMBJ13A and 1.5KE13A, the 1.5SMC13H uniquely combines AEC-Q101 qualification, ISO 7637-2 compliance, and 1500W SMT capability in DO-214AB - making it the only drop-in solution for production automotive 12V rail protection requiring zero layout change from legacy 1.5SMC-series designs.

FAQ
What is the breakdown voltage range of the 1.5SMC13H?
The 1.5SMC13H has a guaranteed breakdown voltage (VBR) range of 11.7V to 14.3V at 1.0mA test current, measured per ANSI/IEEE C62.35. This ensures consistent avalanche initiation across production lots and supports design margining for 12V nominal systems.
Is the 1.5SMC13H suitable for bidirectional transient protection?
No - the 1.5SMC13H is unidirectional. For bidirectional protection, select the 1.5SMC13AH variant (marked DVJ), which provides symmetrical clamping in both polarities and uses CH/CAH suffixes per TSC's ordering convention.
Does the 1.5SMC13H meet automotive qualification standards?
Yes - the 1.5SMC13H is AEC-Q101 qualified and tested to ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms. Its glass-passivated junction and JESD201 Class 2 whisker resistance further validate suitability for under-hood automotive applications.
What is the maximum clamping voltage of the 1.5SMC13H under surge conditions?
The 1.5SMC13H clamps to a maximum of 19.0V at its rated 82A peak impulse current (IPPM) using the standard 10/1000µs waveform. This value is guaranteed across temperature and lifetime per TSC's characterization data.
Can the 1.5SMC13H be used in high-humidity environments?
Yes - the 1.5SMC13H features a glass-passivated chip junction and meets J-STD-020 Level 1 moisture sensitivity, enabling direct reflow without baking. Its UL 94V-0 molding compound also resists environmental degradation in humid industrial enclosures.
