Product details
Overview
SMCJ60H from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 60V working stand-off voltage (VWM), 66.7–81.5V breakdown voltage (VBR), and 107V maximum clamping voltage (VC) at 14A peak pulse current-designed to protect automotive power rails and industrial I/O interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the SMCJ60H datasheet, SMCJ60H pinout, SMCJ60H application, or SMCJ60H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance values, moisture sensitivity level (MSL 1), and real-world clamping performance under standardized 10/1000μs surge waveforms.
Technical Context
The SMCJ60H uses a glass-passivated silicon junction optimized for fast response (<1.0 ps rise from 0 V to VBR min) and low leakage (<1 μA at 60 V), meeting stringent automotive EMC immunity requirements per ISO 7637-2 across all five defined test pulses. Its unidirectional configuration enables asymmetric protection of DC power lines without reverse-bias conduction during normal operation.
Thermal design is supported by RθJA = 55°C/W and RθJC = 10°C/W, enabling reliable 1500W peak pulse dissipation at TA = 25°C with derating above ambient. The device operates over –55°C to +150°C junction temperature range and complies with JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | 600 W peak power rating, SMB package (smaller footprint, higher RθJA = 85°C/W) | Limited to lower-energy transients; unsuitable for full ISO 7637-2 Pulse 5a compliance | Select when board space is constrained and surge energy remains below 600 W |
| 1.5KE60A | Through-hole DO-201 package, same 60 V VWM but slower response (~1 ns), higher clamping (108 V) | Not AEC-Q101 qualified; lacks ISO 7637-2 validation; requires manual assembly | Choose only for non-automotive, cost-sensitive through-hole designs with relaxed transient standards |
Compared with SMBJ60A and 1.5KE60A, the SMCJ60H delivers 2.5× higher surge power handling, AEC-Q101 qualification, and verified ISO 7637-2 compliance-making it the preferred choice for automotive and industrial surface-mount systems requiring robust, automated, and standards-aligned transient protection.

FAQ
What is the clamping voltage of the SMCJ60H under standard surge conditions?
The SMCJ60H exhibits a maximum clamping voltage (VC) of 107 V when subjected to a 10/1000 μs waveform peak pulse current (IPPM) of 14 A. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events. The SMCJ60H maintains this clamping performance consistently across its operational temperature range and after repeated surge exposures, as verified in TSC's qualification testing.
Is the SMCJ60H suitable for automotive applications?
Yes, the SMCJ60H is AEC-Q101 qualified and explicitly tested to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements-making it suitable for automotive power line and signal line protection. Its DO-214AB package supports automated placement, and its –55°C to +150°C operating range covers under-hood and cabin environments. The SMCJ60H is not intended for safety-critical medical or life-sustaining systems per TSC's notice.
What is the difference between SMCJ60H and SMCJ60AH?
The SMCJ60AH variant has a tighter breakdown voltage tolerance (66.7–73.7 V vs. 66.7–81.5 V for SMCJ60H) and slightly lower clamping voltage (96.8 V vs. 107 V at rated IPPM), achieved via enhanced process control. Both share identical VWM (60 V), package (DO-214AB), and AEC-Q101 qualification. The SMCJ60H offers broader VBR distribution for cost-sensitive applications where tighter tolerances are unnecessary.
Does the SMCJ60H have polarity markings, and how is it oriented on the PCB?
Yes, the SMCJ60H features a cathode band (distinctive marking) on one end of the DO-214AB body, indicating the cathode terminal. During PCB layout, the banded end must connect to the line being protected (e.g., +12 V rail), while the anode connects to ground. Incorrect orientation renders the device ineffective for unidirectional surge suppression. The SMCJ60H's polarity is confirmed in TSC's marking diagram and mechanical drawings.
What is the moisture sensitivity level (MSL) and reflow profile guidance for SMCJ60H?
The SMCJ60H is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be subjected to standard lead-free reflow profiles without baking. Its matte tin-plated leads comply with J-STD-002 for solderability, and the molding compound meets UL 94V-0 flammability. Reflow peak temperature should not exceed 260°C for ≤30 seconds, consistent with IPC/JEDEC J-STD-020D.3 guidelines for DO-214AB packages.
