Product details
Overview
3.0C90CA-M3 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for high-energy surge protection with 3000 W peak pulse power (10/1000 μs), 100–111 V breakdown voltage, and 146 V clamping voltage at 20.5 A IPPM. It protects MOSFETs, ICs, and sensor signal lines in industrial power supplies and telecom interfaces.
For engineers reviewing the 3.0C90CA-M3 datasheet, 3.0C90CA-M3 pinout, 3.0C90CA-M3 application, or 3.0C90CA-M3 equivalent, key selection criteria include bidirectional clamping capability, 175 °C junction temperature rating, MSL Level 1 moisture sensitivity, and compliance with IEC 61000-4-2 (30 kV ESD).
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within nanoseconds to transients induced by inductive switching or lightning surges. Its low incremental surge resistance and fast response time ensure minimal overvoltage exposure to downstream components.
The device features a silicon avalanche structure optimized for stable bidirectional clamping across -55 °C to +175 °C operation. Thermal resistance junction-to-mount is 4.0 °C/W, enabling effective heat dissipation when soldered to copper pads per JEDEC 51-14 TDIM methodology.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 100–111 V at 1 mA test current - defines minimum voltage at which avalanche conduction begins reliably |
| Stand-off Voltage VWM | 90 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| Clamping Voltage VC | 146 V at 20.5 A (10/1000 μs) - peak voltage seen by protected circuit during rated surge |
| Peak Pulse Power PPPM | 3000 W (10/1000 μs) - energy-handling capacity for standard lightning-surge waveform |
| Junction Temperature Range | -55 °C to +175 °C - supports operation in harsh industrial and automotive under-hood environments |
| ESD Immunity | 30 kV per IEC 61000-4-2 (contact & air discharge) - qualifies for high-reliability end-equipment certification |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 0.320" body length and matte tin-plated leads |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case meeting UL 94 V-0 flammability rating; terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102; -M3 suffix indicates halogen-free, RoHS-compliant, industrial-grade construction with JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Surge current return path for negative transients | Bidirectional operation means this terminal conducts during both polarities; no polarity marking on device body |
| Anode | Surge current return path for positive transients | Functions identically to cathode under reverse bias due to symmetrical avalanche structure |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 30 kW surge rating (8/20 μs) | Supports IEC 61000-4-5 Level 4 immunity testing (4 kV line-to-line, 2 kV line-to-ground) |
| Low clamping ratio (VC/VBR ≈ 1.32) | Minimizes overvoltage stress on protected ICs compared to higher-ratio suppressors |
| MSL Level 1 rating | Allows unlimited floor life and reflow at peak 260 °C without baking preconditioning |
| 175 °C max junction temperature | Permits use in high-ambient environments such as motor drives and base station power stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ90A-E3/5AT | Unidirectional; 90 V VWM; 146 V VC at 20.5 A; same SMC package but lacks bidirectional symmetry | Requires polarity-aware layout; unsuitable for AC or floating differential signals | Select only when circuit topology guarantees unidirectional surge polarity and space constraints favor footprint compatibility |
| 1.5KE91CA | Through-hole DO-201 package; 91 V VWM; 146 V VC; 1500 W PPPM - half the surge rating of 3.0C90CA-M3 | Not suitable for high-density SMT designs; lower power handling limits use in high-energy surge zones | Consider only for legacy through-hole systems where rework cost outweighs performance trade-off |
Compared with SMAJ90A-E3/5AT and 1.5KE91CA, the 3.0C90CA-M3 delivers full bidirectional protection in an SMT package with double the peak pulse power, making it optimal for modern compact designs requiring robust, polarity-agnostic surge immunity.

FAQ
What is the maximum clamping voltage of the 3.0C90CA-M3 under standard surge conditions?
The 3.0C90CA-M3 exhibits a maximum clamping voltage of 146 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 20.5 A. This value is measured per ANSI/IEEE C62.35 standards and ensures predictable overvoltage limiting for downstream 90 V-rated components. The clamping voltage remains stable across its full operating temperature range.
Is the 3.0C90CA-M3 suitable for bidirectional signal line protection?
Yes, the 3.0C90CA-M3 is explicitly designed as a bidirectional TVS diode, with symmetrical avalanche characteristics enabling identical clamping behavior for both positive and negative transients. Its unmarked SMC package reflects this inherent polarity independence, making it ideal for protecting AC-coupled interfaces like RS-485, CAN, or audio lines without orientation concerns.
Does the 3.0C90CA-M3 meet moisture sensitivity level requirements for lead-free reflow?
Yes, the 3.0C90CA-M3 meets MSL Level 1 per J-STD-020, allowing unlimited floor life and compatibility with standard lead-free reflow profiles peaking at 260 °C. No baking or dry-pack handling is required prior to assembly, simplifying manufacturing logistics and reducing process risk for high-volume SMT lines.
What is the thermal resistance from junction to mount for the 3.0C90CA-M3?
The thermal resistance from junction to mount (RthJM) for the 3.0C90CA-M3 is 4.0 °C/W, measured using the Transient Dual Interface Method (TDIM) per JEDEC 51-14. This low value enables efficient heat transfer to the PCB copper pad, supporting sustained operation at elevated ambient temperatures when mounted on ≥1 sq-in. 2 oz. copper area.
How does the 3.0C90CA-M3 perform under IEC 61000-4-2 ESD testing?
The 3.0C90CA-M3 is rated for 30 kV ESD immunity per IEC 61000-4-2 in both contact and air discharge modes. This performance is achieved through optimized silicon geometry and metallization, ensuring reliable protection for sensitive inputs in consumer, industrial, and telecom equipment without degradation after repeated discharges.
