Product details
Overview
3.0C30CA-M3/H 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), 30 V stand-off voltage (VWM), and 48.4 V maximum clamping voltage at 62.0 A IPPM. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment against lightning and inductive switching transients.
For engineers reviewing the 3.0C30CA-M3/H datasheet, 3.0C30CA-M3/H pinout, 3.0C30CA-M3/H application, or 3.0C30CA-M3/H 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 picoseconds to transient overvoltages exceeding its reverse stand-off voltage (VWM = 30 V). Its silicon avalanche structure provides low incremental surge resistance and stable breakdown (VBR = 33.3–36.8 V at 1.0 mA), enabling precise clamping at VC = 48.4 V under 10/1000 μs pulses.
It meets JEDEC J-STD-020 MSL Level 1, supports reflow up to 260 °C peak, and delivers 30 kV ESD immunity per IEC 61000-4-2 contact/air discharge. Thermal resistance is RthJA = 90 °C/W (FR4, 2 oz Cu) and RthJM = 4.0 °C/W, supporting high-reliability operation in compact PCB layouts.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30CA | Same VWM (30 V), lower PPPM (600 W), SMB package (smaller footprint, higher RthJA) | Lower energy handling; suitable only for sub-1 kV surge environments like consumer USB ports | Select 3.0C30CA-M3/H when >2 kV surge immunity and industrial thermal margin are required |
| SMCJ30CA | Identical VWM (30 V), same SMC package, but rated for 1500 W PPPM (10/1000 μs) | Limited to medium-energy transients; not validated for 30 kV ESD or 175 °C TJ operation | Choose 3.0C30CA-M3/H for full compliance with IEC 61000-4-2, -4-5, and extended temperature reliability |
Compared with SMBJ30CA and SMCJ30CA, the 3.0C30CA-M3/H delivers double the pulse power rating, guaranteed 30 kV ESD immunity, and full 175 °C junction capability-making it the preferred choice for mission-critical industrial and telecom surge protection where long-term reliability under repeated stress is mandatory.

FAQ
What is the maximum clamping voltage of the 3.0C30CA-M3/H under a 10/1000 μs surge?
The 3.0C30CA-M3/H has a maximum clamping voltage (VC) of 48.4 V when subjected to its rated peak pulse current of 62.0 A using the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees predictable overvoltage limiting for downstream circuitry during standardized surge events.
Is the 3.0C30CA-M3/H suitable for lead-free reflow soldering?
Yes, the 3.0C30CA-M3/H is qualified for lead-free reflow with a maximum peak temperature of 260 °C per J-STD-020, and carries MSL Level 1 rating-meaning it can be stored indefinitely at ambient conditions and assembled in a single reflow pass without baking or moisture mitigation.
Does the 3.0C30CA-M3/H have polarity markings on the package?
No, the 3.0C30CA-M3/H is a bidirectional TVS diode and carries no polarity marking on the SMC (DO-214AB) case. Its symmetrical construction allows installation without orientation concern on AC-coupled or differential signal lines.
What is the thermal resistance junction-to-ambient for the 3.0C30CA-M3/H?
The 3.0C30CA-M3/H has a typical thermal resistance junction-to-ambient (RthJA) of 90 °C/W when mounted on a standard FR4 PCB with 2 oz copper and the recommended pad layout. This value assumes JEDEC 51-2A test conditions and is critical for estimating temperature rise under sustained leakage or repetitive surge conditions.
How does the 3.0C30CA-M3/H compare to standard Zener diodes for surge protection?
Unlike general-purpose Zener diodes, the 3.0C30CA-M3/H is optimized for transient suppression: it features lower dynamic impedance, faster response (<1 ns), higher peak power (3000 W), and guaranteed clamping performance under standardized surge waveforms. Zeners lack specified PPPM, IPPM, or ESD ratings-and degrade rapidly under repeated surges.
