Product details

Overview

3.0C100CA-M3 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 3000 W peak pulse power (10/1000 μs), 162 V clamping voltage at 18.5 A, and 100 V stand-off voltage. It protects MOSFETs, ICs, and sensor signal lines in industrial power supplies and telecom interfaces against lightning-induced transients.

For engineers reviewing the 3.0C100CA-M3 datasheet, 3.0C100CA-M3 pinout, 3.0C100CA-M3 application, or 3.0C100CA-M3 equivalent, key selection criteria include clamping voltage vs. stand-off margin, bidirectional polarity for AC-coupled lines, SMC package thermal performance (R_thJA = 90 °C/W), and IEC 61000-4-2 ESD immunity up to 30 kV.

Technical Context

This TVS diode operates as a voltage-clamped crowbar device triggered by reverse-biased avalanche breakdown above V_BR = 111–123 V. Its low incremental surge resistance ensures stable clamping under high-current 10/1000 μs pulses up to 18.5 A, while maintaining <1 μA leakage at 100 V stand-off.

Designed for surface-mount assembly on FR4 PCBs with 2 oz copper, it meets MSL Level 1 per J-STD-020 and supports reflow up to 260 °C peak. The halogen-free, RoHS-compliant -M3 suffix confirms compliance with JESD 201 Class 2 whisker testing and UL 94 V-0 molding compound rating.

Key Specifications

Parameter	Value and Actual Design Meaning
V_WM	100 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold.
V_BR min/max	111 V / 123 V - Breakdown voltage range at 1 mA test current; ensures reliable triggering across process variation.
V_C @ I_PPM	162 V @ 18.5 A - Clamping voltage during 10/1000 μs surge; limits downstream voltage stress to ≤162 V under worst-case transient.
P_PPM	3000 W - Peak pulse power handling (10/1000 μs); supports robust protection in industrial motor drives and PoE injectors.
T_J max	+175 °C - Maximum junction temperature; enables operation in high-ambient environments like enclosed power converters.
ESD Rating	30 kV - Human body model (HBM) contact/air discharge immunity per IEC 61000-4-2; eliminates need for additional ESD stages on protected lines.

Pinout & Package

Package: SMC (DO-214AB), surface-mount, bidirectional device with unmarked cathode/anode terminals; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Transient current sink (bidirectional)	Conducts surge current in either polarity; no polarity marking required due to symmetrical construction.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ100CA	Lower P_PPM = 600 W; same V_WM = 100 V but higher V_C = 165 V @ 3.6 A; SMB package (smaller footprint, higher R_thJA).	Best suited for space-constrained consumer electronics where surge energy is limited to <600 W.	Select when board area is critical and surge threat level is lower than industrial-grade requirements.
SMCJ100CA	Same SMC package and P_PPM = 3000 W, but V_BR = 111–123 V identical; differs only in marking code and reel packaging (no functional difference).	No application difference - direct form-fit-function replacement with identical electrical and thermal behavior.	Choose for sourcing flexibility if 3.0C100CA-M3 lead times are extended; verify reel size compatibility (I = 3500 pcs vs. standard SMCJ reels).

Compared with SMBJ100CA, 3.0C100CA-M3 delivers 5× higher surge energy handling and lower thermal resistance; versus SMCJ100CA, it offers identical protection performance with Vishay's -M3 halogen-free, whisker-tested qualification for harsh-environment deployments.

FAQ

What is the maximum clamping voltage of the 3.0C100CA-M3 under a 10/1000 μs surge?

The 3.0C100CA-M3 has a maximum clamping voltage (V_C) of 162 V when subjected to its rated peak pulse current of 18.5 A using the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures downstream components see no more than 162 V during surge events. The 3.0C100CA-M3 datasheet specifies this parameter in the Electrical Characteristics table under "MAXIMUM CLAMPING VOLTAGE VC (V) AT IPPM".

Does the 3.0C100CA-M3 have polarity markings on the package?

No, the 3.0C100CA-M3 does not have polarity markings because it is a bidirectional TVS diode. Its symmetrical construction allows installation in either orientation on the PCB without affecting performance. The SMC (DO-214AB) package uses unmarked matte tin-plated terminals, consistent with Vishay's specification for bidirectional variants in the 3.0CxxCA-M3 family.

What is the thermal resistance from junction to ambient for the 3.0C100CA-M3?

The 3.0C100CA-M3 has a typical junction-to-ambient thermal resistance (R_thJA) of 90 °C/W when mounted on a standard FR4 PCB with 2 oz copper, per JEDEC 51-2A. This value assumes the recommended mounting pad layout shown in the Vishay datasheet and is critical for calculating maximum power dissipation at elevated ambient temperatures. Derating curves in the 3.0C100CA-M3 datasheet confirm thermal performance up to +175 °C junction temperature.

Is the 3.0C100CA-M3 compliant with RoHS and halogen-free standards?

Yes, the 3.0C100CA-M3 carries the -M3 suffix, which certifies it as halogen-free, RoHS-compliant, and industrial grade. It meets JESD 201 Class 2 whisker testing and uses UL 94 V-0 rated molding compound. These qualifications are documented in the Vishay 3.0C100CA-M3 datasheet under Mechanical Data and Material Categorization sections.

What is the ESD immunity rating of the 3.0C100CA-M3?

The 3.0C100CA-M3 is rated for 30 kV ESD immunity per IEC 61000-4-2 in both contact and air discharge modes. This high-level protection is intrinsic to its TVS structure and eliminates the need for supplemental ESD protection on lines where the 3.0C100CA-M3 is deployed as the primary surge suppressor. The rating is verified per the test conditions specified in the 3.0C100CA-M3 datasheet's Immunity section.
