Product details
Overview
1.5SMC16CH from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) diode with a 16V working stand-off voltage (VWM = 12.9V), 14.4–17.6V breakdown voltage (VBR), and 23.5V maximum clamping voltage (VC) at 67A peak impulse current. It features glass passivated junction, AEC-Q101 qualification, and ISO 7637-2 compliance for automotive load-dump and ESD protection in power supply rails.
For engineers reviewing the 1.5SMC16CH datasheet, 1.5SMC16CH pinout, 1.5SMC16CH application, or 1.5SMC16CH equivalent, this device is selected for high-energy transient suppression in 12V automotive subsystems, industrial DC inputs, and telecom interface protection where fast response (<1.0 ps), low leakage (<1 µA @ 12.9V), and DO-214AB package compatibility are critical.
Technical Context
The 1.5SMC16CH operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its VBR range (14.4–17.6V at 1mA test current). Its clamping action limits transients to ≤23.5V at 67A (10/1000µs waveform), enabling robust protection of downstream MOSFETs, controllers, and communication ICs.
Thermally rated for TJ = –55°C to +150°C, it delivers 6.5W steady-state dissipation and 1500W peak pulse power (tp = 1ms), with RθJA = 50°C/W and RθJC = 15°C/W. Polarity is marked by cathode band; moisture sensitivity level is J-STD-020 Level 1.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Bidirectional variant; same VBR (14.4–17.6V), but symmetric clamping in both polarities; slightly lower PPK (600W) | Suitable for AC-coupled or dual-rail protection where reverse polarity transients occur | Select SMBJ16A only if bidirectional clamping is required; 1.5SMC16CH offers 2.5× higher surge energy handling |
| 1.5KE16A | Through-hole DO-201 package; identical electrical specs but larger footprint and manual assembly requirement | Used in legacy industrial power supplies where board space and automated assembly are not constraints | Choose 1.5KE16A for prototyping or low-volume through-hole designs; 1.5SMC16CH enables high-density SMT production |
Compared with SMBJ16A and 1.5KE16A, the 1.5SMC16CH provides superior surge capacity (1500W vs. 600W/600W), DO-214AB SMT compatibility, and AEC-Q101 qualification-making it optimal for automotive and high-reliability industrial applications requiring automated manufacturing and high-energy immunity.

FAQ
What is the polarity configuration of the 1.5SMC16CH?
The 1.5SMC16CH is a unidirectional TVS diode, with cathode marked by a band on the DO-214AB package. It conducts only during reverse overvoltage events on the cathode side and blocks forward current like a standard diode. This configuration is optimized for DC rail protection where polarity is fixed, such as 12V automotive power lines.
Does the 1.5SMC16CH meet AEC-Q101 requirements for automotive use?
Yes, the 1.5SMC16CH is explicitly AEC-Q101 qualified per the Taiwan Semiconductor datasheet (Version B2207). It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD, confirming suitability for under-hood and body-control applications in passenger vehicles and commercial vehicles.
What is the maximum clamping voltage of the 1.5SMC16CH under surge conditions?
The 1.5SMC16CH exhibits a maximum clamping voltage (VC) of 23.5 V at 67 A peak impulse current (IPPM), tested with the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is guaranteed across the full operating temperature range.
How does the 1.5SMC16CH differ from the 1.5SMC16AH variant?
The 1.5SMC16AH has a tighter VBR tolerance (15.2–16.8 V vs. 14.4–17.6 V for the 1.5SMC16CH) and slightly lower clamping voltage (22.5 V vs. 23.5 V). Both share identical package, power rating, and AEC-Q101 qualification, but the 1.5SMC16CH offers broader breakdown range for cost-sensitive designs where tighter VBR is not required.
Is the 1.5SMC16CH compliant with RoHS and halogen-free standards?
Yes, the 1.5SMC16CH is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the official Taiwan Semiconductor documentation. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 solderability requirements.
