Product details
Overview
3.0C36CA-M3/H 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), 58.1 V clamping voltage at 51.6 A, and 40.0–44.2 V breakdown voltage. It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom power rails.
For engineers reviewing the 3.0C36CA-M3/H datasheet, 3.0C36CA-M3/H pinout, 3.0C36CA-M3/H application, or 3.0C36CA-M3/H equivalent, key selection criteria include bidirectional clamping capability, 175 °C max junction temperature, 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 transients induced by inductive switching or lightning surges. Its bidirectional architecture enables symmetric clamping across both polarities without polarity marking, and its low incremental surge resistance ensures stable clamping under high-current 8/20 μs waveforms (76.0 V at 395 A).
Thermal performance is defined by RthJA = 90 °C/W and RthJM = 4.0 °C/W, supporting reliable operation up to 175 °C junction temperature. The device meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability standards, with matte tin-plated leads solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 40.0 V / 44.2 V - Ensures reliable triggering above 36 V stand-off while avoiding false trips during normal operation. |
| VWM | 36 V - Maximum continuous reverse operating voltage before leakage exceeds 1.0 μA. |
| VC @ IPPM (10/1000 μs) | 58.1 V at 51.6 A - Clamps transient spikes to safe levels for downstream 3.3 V/5 V/12 V logic and power stages. |
| PPPM | 3000 W - Sustains high-energy surges typical of industrial motor drives and telecom line interfaces. |
| TJ max | 175 °C - Enables use in high-ambient environments such as enclosed power supplies and base station equipment. |
| ESD immunity | 30 kV contact/air (IEC 61000-4-2) - Provides robust handling protection during assembly and field service. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL Level 1, 260 °C reflow peak. Dimensions: 7.11 mm × 6.22 mm × 2.62 mm (L × W × H). Matte tin-plated terminals, unmarked polarity for bidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode side marked "K" on unidirectional variants; not marked on 3.0C36CA-M3/H) | Transient current return path | Bidirectional design eliminates need for polarity orientation-either terminal serves as anode or cathode depending on transient polarity. |
| Anode (unmarked) | Transient current entry point | Enables symmetrical clamping; no PCB layout constraints for orientation during placement. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Eliminates polarity-dependent layout errors and supports AC-coupled or floating signal lines without external diode pairing. |
| 30 kW surge rating (8/20 μs) | Withstands telecom lightning surges (IEC 61000-4-5) up to 395 A peak without degradation. |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes overvoltage stress on protected ICs-critical for 3.3 V microcontrollers and RS-485 transceivers. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking, reducing manufacturing overhead. |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protection of gate drivers and DC-link sensing circuits against commutation spikes from IGBTs and MOSFETs. IC Role / Device Role / Timing Role: Shunt clamping element placed directly across power rail inputs or gate drive traces. Use Value: Limits transient overshoot to ≤58.1 V, preventing latch-up or oxide breakdown in 60 V-rated gate drivers. | Use Scenario: Surge suppression on -48 V telecom power distribution boards exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary front-end TVS on power entry, coordinated with upstream MOVs and downstream filtering. Use Value: Absorbs 3000 W (10/1000 μs) surges while maintaining <1.0 μA leakage at nominal -48 V operation. |
| Automotive Body Control Modules | Industrial Sensor Signal Conditioning |
Use Scenario: Protecting LIN bus transceivers and power window motor controllers from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamp on 12 V supply rail, placed upstream of LDOs and CAN/LIN PHYs. Use Value: Withstands 30 kV ESD (IEC 61000-4-2) and clamps 12 V rail transients to <60 V, preserving signal integrity. | Use Scenario: Shielding analog outputs (4–20 mA, 0–10 V) of pressure/temperature sensors from EFT and surge coupling. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF at 0 V) shunt protector on signal line +VS and return paths. Use Value: Adds <0.5 ns propagation delay and maintains signal fidelity due to fast response and minimal parasitic loading. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | Lower PPPM (600 W), same SMC package, VBR = 40–44.2 V, VC = 58.1 V @ 10.3 A | Not suitable for 3000 W surge events; limited to lower-energy ESD/EFT scenarios. | Select when cost sensitivity outweighs surge energy requirement and board space allows parallel staging. |
| SMCJ36CA | Same PPPM (3000 W), identical VBR/VC, but rated for 175 °C TJ and MSL Level 1 - functionally identical in electrical specs and thermal envelope. | No functional difference; alternate manufacturer marking for same Vishay die and construction. | Valid drop-in alternative if 3.0C36CA-M3/H is unavailable; verify reel packaging code (H vs. standard M3) for assembly compatibility. |
Compared with SMBJ36CA and SMCJ36CA, the 3.0C36CA-M3/H delivers identical clamping performance at full 3000 W rating in the same SMC footprint, while offering guaranteed 30 kV ESD immunity and JESD 201 Class 2 whisker resistance-critical for high-reliability industrial deployments.

FAQ
What is the maximum clamping voltage of the 3.0C36CA-M3/H under a 10/1000 μs surge?
The 3.0C36CA-M3/H clamps to a maximum of 58.1 V when subjected to its rated peak pulse current of 51.6 A using the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet (Doc #98266, Rev 09-Jan-2024), ensuring predictable overvoltage limiting for protected circuitry.
Is the 3.0C36CA-M3/H suitable for bidirectional signal line protection?
Yes, the 3.0C36CA-M3/H is explicitly designed as a bidirectional TVS diode with symmetrical breakdown and clamping characteristics. Its unmarked terminals and matched VBR/VC behavior in both polarities make it ideal for protecting AC-coupled interfaces like RS-485, CAN, or audio lines where polarity reversal may occur.
Does the 3.0C36CA-M3/H meet automotive reliability standards?
The 3.0C36CA-M3/H is not AEC-Q200 qualified, but it meets JESD 201 Class 2 whisker resistance, MSL Level 1, and 175 °C TJ max-key requirements for under-hood and body control module use. For full automotive qualification, consult Vishay's AEC-Q200-certified equivalents such as the AUTOMOTIVE-grade SMCJ36CA-A.
What is the junction-to-ambient thermal resistance (RthJA) of the 3.0C36CA-M3/H?
The 3.0C36CA-M3/H has a typical RthJA of 90 °C/W when mounted on a standard FR4 PCB with 2 oz. copper per JEDEC 51-2A. This value assumes the recommended SMC pad layout; actual thermal performance improves significantly with enhanced copper pour or thermal vias.
Can the 3.0C36CA-M3/H replace the older 3.0C36A-M3 in existing designs?
Yes-the 3.0C36CA-M3/H is a direct replacement for the legacy 3.0C36A-M3, retaining identical electrical specifications, package dimensions, and thermal ratings. The "CA" suffix denotes bidirectional configuration (vs. unidirectional "A"), and "-M3/H" confirms halogen-free, RoHS-compliant construction with 7" tape-and-reel packaging.
