Product details
Overview
1.5SMC13CH from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 1500W peak pulse power, 13V nominal breakdown voltage (11.7–14.3V), and clamping voltage of 19.0V 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 1.5SMC13CH datasheet, 1.5SMC13CH pinout, 1.5SMC13CH application, or 1.5SMC13CH equivalent, this device offers AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, sub-1ps response time, and <1μA leakage above 10V - critical for robust front-end protection in harsh environments.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with breakdown voltage specified at 1mA test current and clamping performance validated per IEC 61000-4-2/4-5 and ISO 7637-2 waveforms. Its glass-passivated junction ensures stable VBR tolerance and low leakage across temperature.
Thermal design is supported by RθJA = 50°C/W and RθJC = 15°C/W, enabling reliable operation up to +150°C junction temperature. The DO-214AB package provides mechanical robustness and automated placement compatibility while meeting UL 94V-0 flammability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.7V / 14.3V - Ensures consistent turn-on threshold across production lots and temperature |
| VWM | 10.5V - Maximum continuous reverse operating voltage before leakage exceeds 1μA |
| VC@IPPM | 19.0V at 82A - Limits downstream voltage stress during 10/1000μs surge events |
| PPK | 1500W - Sustains high-energy transients without failure per Fig.5 waveform |
| IR@VWM | <1μA - Minimizes standby power loss and avoids false triggering in high-impedance circuits |
| TJ max | +150°C - Enables use in under-hood automotive and industrial power supply applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Same DO-214AA (SMB) package; lower 600W PPK, higher VC = 21.5V @ 27.3A | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a (load dump) | Select when space-constrained layouts require smaller footprint and surge energy is ≤600W |
| 1.5KE13CA | Through-hole DO-15 package; same 1500W rating but slower thermal response and no AEC-Q101 qualification | Not suitable for automotive or high-reliability automated assembly; requires wave soldering | Choose only for legacy through-hole designs where rework flexibility outweighs automotive compliance needs |
Compared with SMBJ13CA and 1.5KE13CA, the 1.5SMC13CH delivers superior surge robustness in surface-mount form with automotive-grade reliability, making it the preferred choice for new automotive and industrial designs requiring AEC-Q101 and ISO 7637-2 compliance.

FAQ
What is the breakdown voltage range for 1.5SMC13CH?
The 1.5SMC13CH has a guaranteed breakdown voltage range of 11.7V to 14.3V at 1mA test current, measured per ANSI/IEEE C62.35. This tolerance ensures predictable clamping behavior across temperature and process variation, critical for maintaining system-level surge immunity margins in automotive and industrial applications where the 1.5SMC13CH is deployed.
Is 1.5SMC13CH unidirectional or bidirectional?
The "CH" suffix explicitly denotes bidirectional configuration - the 1.5SMC13CH conducts symmetrically in both polarities, with identical VBR, VC, and IPPM specifications for positive and negative surges. Unlike "H"-suffix unidirectional variants, the 1.5SMC13CH requires no polarity marking and is ideal for AC-coupled or floating-rail protection where voltage reversal is possible.
Does 1.5SMC13CH meet automotive qualification standards?
Yes, the 1.5SMC13CH is AEC-Q101 qualified and meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements - essential for automotive electronic control units, body electronics, and infotainment systems. Its DO-214AB package supports automated placement, and its moisture sensitivity level 1 eliminates pre-reflow baking, aligning with automotive manufacturing best practices for the 1.5SMC13CH.
What is the maximum clamping voltage of 1.5SMC13CH under surge conditions?
The 1.5SMC13CH clamps to a maximum of 19.0V at 82A peak impulse current (10/1000μs waveform), as specified in the Electrical Specifications table. This value defines the upper voltage limit imposed on protected circuitry during worst-case transients, ensuring downstream components such as 24V-rated regulators or CAN transceivers remain within absolute maximum ratings when the 1.5SMC13CH is used.
Can 1.5SMC13CH replace 1.5SMC13H in a design?
No - the 1.5SMC13CH is bidirectional while the 1.5SMC13H is unidirectional. Substituting them without circuit review risks improper clamping during reverse-polarity transients. The 1.5SMC13CH has no cathode band and symmetrical terminals; the 1.5SMC13H requires correct orientation. Layout, schematic symbol, and system-level surge testing must be revalidated if swapping the 1.5SMC13CH for 1.5SMC13H.
