Product details
Overview
SMCJ60CH from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) 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 impulse current - designed to protect automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the SMCJ60CH datasheet, SMCJ60CH pinout, SMCJ60CH application, or SMCJ60CH equivalent, this device delivers AEC-Q101 qualification, sub-1ps response time, <1μA reverse leakage above 10V, glass-passivated junction, and bidirectional ESD/transient immunity for robust front-end protection in harsh environments.
Technical Context
The SMCJ60CH implements a single-die, bidirectional avalanche structure optimized for fast clamping of high-energy transients without degradation under repeated stress. Its VWM = 60V and VC = 107V at IPPM = 14A define precise overvoltage thresholds for 48V and 60V system rails.
Thermal performance is characterized by RθJA = 55°C/W and RθJC = 10°C/W, supporting sustained operation up to TJ = +150°C. It meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity - enabling direct placement in automotive PCB assembly lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 66.7 / 81.5 V @ IT = 1 mA - Confirmed avalanche onset range for reliable turn-on margin |
| VC @ IPPM | 107 V @ 14 A - Clamped voltage during 10/1000μs surge, limiting downstream stress |
| PPK | 1500 W - Peak pulse power handling per single 1ms transient per Fig.5 |
| IR @ VWM | <1 μA - Negligible leakage at rated stand-off, preserving low-power circuit integrity |
| TJ max | +150 °C - Junction temperature limit enabling under-hood automotive deployment |
| Package | DO-214AB (SMC) - Standardized surface-mount outline with 0.210g mass and UL 94V-0 molding |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with matte tin-plated leads, cathode band marking polarity for unidirectional variants; SMCJ60CH is bidirectional and marked with "GGH" code - no polarity band required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient conduction path | Both terminals function identically - enables placement without orientation check in PCB layout |
| Case (exposed pad not present) | Non-conductive thermal path | No electrical connection; thermal dissipation occurs via leadframe conduction to PCB copper |
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 load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line decoupling) waveforms |
| Glass-passivated junction | Enhances long-term stability and reduces parameter drift under humidity and thermal stress |
| Sub-1ps response time | Clamps within 1 picosecond from 0 V to VBR min - faster than most microcontroller I/O protection needs |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU Directive 2011/65/EU for environmentally constrained supply chains |
Applications
| Automotive Power Distribution | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting 48V battery-fed ECUs and gate drivers from load dump and alternator transients. IC Role / Device Role / Timing Role: Primary clamping element across main power rail, placed upstream of DC-DC converters and MCU power inputs. Use Value: Limits rail voltage to ≤107V during 14A surges, preventing damage to 65V-rated MOSFETs and PMICs. | Use Scenario: Safeguarding analog input modules in programmable logic controllers exposed to field wiring surges. IC Role / Device Role / Timing Role: Bidirectional TVS on signal/power interface pins to absorb induced lightning and switching noise. Use Value: Maintains signal integrity below 107V clamping level while adding <1μA leakage - no impact on 24V sensor bias networks. |
| Telecom Base Station Power | Renewable Energy Inverter Control |
Use Scenario: Front-end protection for 48V telecom rectifier outputs subjected to grid coupling transients. IC Role / Device Role / Timing Role: Standoff-clamp device parallel to bulk capacitor, absorbing energy before it reaches downstream regulators. Use Value: Handles 1500W peak pulses without derating at 25°C - supports high-reliability N+1 redundant power designs. | Use Scenario: DC-link surge suppression in solar string inverters where PV array transients couple into control board supplies. IC Role / Device Role / Timing Role: Bidirectional clamp on isolated 60V auxiliary supply rail feeding gate drivers and isolation ICs. Use Value: Withstands repeated 10/1000μs surges per IEC 61000-4-5 while maintaining VWM = 60V - avoids false triggering during normal operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA | 600W rating, SMB package (smaller footprint, higher RθJA = 85°C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 1 full amplitude | Select when space-constrained and peak surge energy ≤600W |
| 1.5KE60CA | Through-hole DO-201 package, same 1500W rating but slower response (~1ns) and no AEC-Q101 qualification | Not suitable for automated SMT lines or automotive under-hood use due to leaded construction and qualification gap | Select only for legacy through-hole designs requiring identical clamping specs |
Compared with SMBJ60CA and 1.5KE60CA, the SMCJ60CH provides higher surge robustness in a surface-mount package with automotive qualification - making it the preferred choice for new 48V/60V automotive and industrial designs requiring production scalability and environmental resilience.

FAQ
What does the "CH" suffix indicate in SMCJ60CH?
The "CH" suffix in SMCJ60CH denotes a bidirectional configuration with glass-passivated junction and AEC-Q101 qualification. Unlike unidirectional "H" variants, SMCJ60CH conducts symmetrically in both directions - eliminating polarity concerns during placement and enabling universal use across AC-coupled or floating bus interfaces. This matches the exact marking code "GGH" and electrical behavior documented in TSC's datasheet revision A2102.
Is SMCJ60CH compliant with ISO 7637-2 for automotive applications?
Yes, SMCJ60CH is explicitly rated to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms per TSC's datasheet. Its 1500W peak power rating, 107V clamping voltage at 14A, and sub-1ps response ensure effective suppression of load dump, switch-off spikes, and line-decoupling transients typical in 12V/24V/48V vehicle networks - confirmed in the "FEATURES" and "ELECTRICAL SPECIFICATIONS" sections of the official documentation.
What is the maximum clamping voltage VC for SMCJ60CH and under what test condition?
The maximum clamping voltage VC for SMCJ60CH is 107 V, measured at a peak impulse current IPPM of 14 A using the standardized 10/1000μs double-exponential waveform defined in Fig.5 of the datasheet. This value is guaranteed across the full operating temperature range and reflects worst-case clamping performance during high-energy transients - critical for ensuring downstream components remain within their absolute maximum voltage ratings.
Does SMCJ60CH require orientation during PCB placement?
No, SMCJ60CH does not require orientation during PCB placement because it is a bidirectional TVS diode. Its symmetrical internal structure means both terminals perform identically under reverse or forward surge conditions - unlike unidirectional variants that feature a cathode band. The DO-214AB (SMC) package carries no polarity marking for SMCJ60CH, simplifying automated assembly and reducing placement errors in high-volume manufacturing.
How does SMCJ60CH compare to SMCJ60AH in terms of breakdown voltage and application suitability?
SMCJ60CH has a VBR range of 66.7–81.5 V, while SMCJ60AH specifies 66.7–73.7 V - indicating tighter VBR distribution for the "A" grade. However, SMCJ60CH is bidirectional and qualified to AEC-Q101, whereas SMCJ60AH is unidirectional and lacks automotive qualification. For applications requiring polarity-agnostic protection in automotive or harsh industrial settings, SMCJ60CH is the technically appropriate selection despite its wider VBR tolerance.
