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 and inductive switching spikes.
For engineers reviewing the 3.0C100CA-M3 datasheet, 3.0C100CA-M3 pinout, 3.0C100CA-M3 application, or 3.0C100CA-M3 equivalent, this page delivers verified electrical parameters, JEDEC-compliant thermal metrics, IEC 61000-4-2 ESD immunity (30 kV contact/air), and precise SMC package mechanical data - all critical for robust overvoltage protection design validation.
Technical Context
This TVS operates as a voltage-clamped shunt device triggered by reverse-biased avalanche breakdown above its 111–123 V breakdown range. Its low incremental surge resistance and sub-nanosecond response time enable effective suppression of fast-rising transients such as 8/20 μs surges (209 V clamping at 144 A) and 10/1000 μs events (162 V at 18.5 A).
Thermal performance is defined by RthJA = 90 °C/W (JEDEC 51-2A, FR4, 2 oz Cu) and RthJM = 4.0 °C/W (JEDEC 51-14 TDIM), supporting reliable operation up to TJ = 175 °C. The -M3 suffix confirms halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance and MSL Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse operating voltage before conduction begins; sets upper limit for circuit bias compatibility. |
| VBR (min/max) | 111 V / 123 V - Breakdown occurs within this range at 1 mA test current; defines turn-on threshold tolerance. |
| VC @ IPPM (10/1000 μs) | 162 V at 18.5 A - Clamped voltage during standard surge event; determines protected circuit's maximum transient exposure. |
| PPPM | 3000 W - Peak pulse power handling per 10/1000 μs waveform; quantifies single-event energy absorption capability. |
| ESD Rating | 30 kV (IEC 61000-4-2, contact & air mode) - Confirms immunity to human-body-model electrostatic discharge without degradation. |
| TJ Range | -55 °C to +175 °C - Full operational junction temperature range; supports deployment in harsh industrial and automotive under-hood environments. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with unmarked cathode/anode terminals - polarity identification not required for symmetrical operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Cathode) | Surge current return path | Both terminals function identically in bidirectional mode; connects across protected line and ground or between differential lines. |
| Cathode (Anode) | Surge current conduction path | No functional distinction; terminal symmetry enables flexible PCB layout without orientation constraints. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables symmetric protection on AC lines or ungrounded differential signals without polarity concerns. |
| 30 kW surge rating (8/20 μs) | Supports compliance with IEC 61000-4-5 Level 4 (4 kV line-to-line, 2 kV line-to-ground) surge testing. |
| Low clamping ratio (VC/VWM = 1.62) | Minimizes overvoltage stress on downstream components during transient events. |
| MSL Level 1, 260 °C reflow compatible | Permits standard lead-free SMT assembly without pre-baking or special handling. |
Applications
| Industrial Motor Drives | Telecom Power Interfaces |
|---|---|
Use Scenario: Protection of gate drivers and bus voltage sensing circuits against back-EMF spikes from relay or contactor switching. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed across DC bus or control signal inputs. Use Value: Limits transient overshoot to ≤162 V, preventing latch-up or oxide rupture in 100 V-rated MOSFETs and op-amps. | Use Scenario: Surge protection on -48 V DC power feeds and RS-485 data lines in central office equipment. IC Role / Device Role / Timing Role: Primary front-end TVS on power input and communication ports. Use Value: Withstands repeated 10/1000 μs surges up to 18.5 A while maintaining <1 μA leakage at 100 V, ensuring low standby loss. |
| Automotive Body Control Modules | Consumer Appliance Sensor Inputs |
Use Scenario: Guarding LIN bus transceivers and microcontroller I/O pins against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Secondary-level clamping device after primary LC filtering. Use Value: 175 °C max junction temperature rating allows placement near heat-generating power stages without derating. | Use Scenario: Shielding analog outputs of temperature/humidity sensors from ESD events during handling or cable coupling. IC Role / Device Role / Timing Role: Board-level ESD suppressor on sensor output traces. Use Value: 30 kV HBM ESD rating prevents field failures in unshielded consumer enclosures without added shielding cost. |
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 PPPM (600 W), same VWM (100 V), SMB package (smaller footprint, higher RthJA) | Suitable only for lower-energy transients; not recommended for IEC 61000-4-5 Level 4 compliance. | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 ESD only. |
| SMCJ100CA | Identical PPPM (3000 W), VWM (100 V), and SMC package; differs in VBR min/max (111–123 V vs. 111–125 V) and VC (162 V vs. 165 V) | Functionally interchangeable in most designs; minor clamping variation requires verification for margin-critical 100 V rail protection. | Preferred for drop-in replacement where Vishay SMCJ series is already qualified in production. |
Compared with SMBJ100CA and SMCJ100CA, the 3.0C100CA-M3 offers identical surge robustness to SMCJ100CA but with tighter VC tolerance and confirmed 30 kV ESD rating - making it optimal for high-reliability industrial systems requiring validated immunity and consistent clamping performance.

FAQ
What is the clamping voltage of the 3.0C100CA-M3 under a 10/1000 μs surge?
The 3.0C100CA-M3 clamps to a maximum of 162 V at 18.5 A under a 10/1000 μs waveform, as specified in the Vishay datasheet (Document Number 98266). This value ensures protected circuits remain below critical overvoltage thresholds during standardized surge events. The 3.0C100CA-M3 maintains this clamping performance across its full operating temperature range.
Does the 3.0C100CA-M3 meet RoHS and halogen-free requirements?
Yes, the 3.0C100CA-M3 carries the -M3 suffix, which certifies halogen-free, RoHS-compliant construction and industrial-grade reliability per Vishay's material categorization standard. It also passes JESD 201 Class 2 whisker testing and meets UL 94 V-0 flammability requirements for the molding compound.
What is the maximum junction temperature rating for the 3.0C100CA-M3?
The 3.0C100CA-M3 has a maximum junction temperature (TJ) rating of +175 °C, enabling operation in high-ambient environments such as industrial motor controls and automotive under-hood applications. Its thermal resistance values - RthJA = 90 °C/W and RthJM = 4.0 °C/W - support thermal design validation per JEDEC standards.
Is the 3.0C100CA-M3 bidirectional or unidirectional?
The 3.0C100CA-M3 is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without polarity marking on the SMC (DO-214AB) package. This makes it ideal for AC line protection, differential data lines, and floating signal paths where voltage polarity reversal may occur.
What packaging format is used for the 3.0C100CA-M3/H variant?
The 3.0C100CA-M3/H variant ships in 7-inch diameter plastic tape and reel packaging, with a base quantity of 850 units per reel. This format is optimized for automated SMT placement and complies with industry-standard handling protocols for moisture-sensitive devices (MSL Level 1).
