Product details
Overview
XMC7K24CA-M3/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 24 V working stand-off voltage, 26.7–29.5 V breakdown voltage, and 24 V max clamping voltage at 180 A (10/1000 µs). It delivers 7000 W peak pulse power, supports −55 °C to +175 °C operation, and is AEC-Q101 qualified for automotive electronics.
For engineers reviewing the XMC7K24CA-M3/H datasheet, XMC7K24CA-M3/H pinout, XMC7K24CA-M3/H application, or XMC7K24CA-M3/H equivalent, key selection criteria include clamping voltage tightness (≤24 V), high-temperature junction capability (175 °C), bidirectional polarity, low leakage (<1.0 µA), and MSL Level 1 reflow compatibility (260 °C peak).
Technical Context
The XMC7K24CA-M3/H employs XClampR® technology to achieve extremely low clamping voltage relative to conventional 7 kW TVS devices, enabling robust protection of sensitive downstream ICs and MOSFETs without overvoltage stress. Its bidirectional structure allows symmetrical suppression of positive and negative transients on signal or power lines.
Rated for 180 A peak pulse current under 10/1000 µs waveform and derated above 25 °C ambient, it maintains stable performance up to TJ = 175 °C - critical for under-hood automotive modules and industrial motor drives where thermal margin is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - maximum continuous reverse operating voltage before conduction begins; defines safe operating window for protected circuitry |
| VBR (min/max) | 26.7 V / 29.5 V - breakdown occurs within this range at 1.0 mA test current; ensures predictable turn-on threshold |
| VCL (max) | 24 V - clamped voltage seen by protected device during 180 A surge; limits stress on downstream components |
| PPPM | 7000 W - peak pulse power handling at 10/1000 µs; enables protection against lightning-induced and inductive-switching transients |
| TJ max | +175 °C - maximum junction temperature rating; supports placement in high-ambient environments like engine control units |
| Polarity | Bidirectional - suppresses both positive and negative voltage spikes without polarity sensitivity |
| IR (max) | 1.0 µA - reverse leakage at rated VWM and 25 °C; minimizes standby power loss and signal distortion |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL Level 1 (260 °C peak reflow), matte tin-plated leads solderable per J-STD-002/JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Surge current sink node | Not applicable - bidirectional device has no functional cathode/anode marking; terminals are electrically symmetric |
| Anode (unmarked end) | Surge current sink node | Not applicable - bidirectional configuration means either terminal conducts during opposite-polarity transients |
Key Features
| Feature | Design Value |
|---|---|
| XClampR® low clamping | Clamps to ≤24 V at 180 A - reduces voltage overshoot below IC absolute maximum ratings |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD - suitable for ECUs and ADAS sensors |
| High-temperature operation | Junction rated to +175 °C - enables use in proximity to heat sources without derating penalties |
| Low leakage current | ≤1.0 µA at 24 V and 25 °C - preserves signal integrity and battery life in always-on systems |
| UL 497B recognition | File E136766 - certifies safety compliance for telecom and industrial interface protection |
Applications
| Automotive Engine Control Unit (ECU) | Industrial Motor Drive Interface |
|---|---|
Use Scenario: Protects microcontroller I/O and CAN transceiver pins from load-dump and alternator ripple transients in 12 V vehicle electrical systems. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector entry point to clamp fast-rising surges before reaching signal conditioning circuitry. Use Value: 24 V clamping ensures protected logic stays below 30 V absolute maximum, preventing latch-up or gate oxide damage in 3.3 V/5 V MCUs. | Use Scenario: Shields analog sensor inputs (e.g., current shunt amplifiers) and digital enable lines from switching noise and back-EMF in variable-frequency drives. IC Role / Device Role / Timing Role: Standoff-rated TVS installed across differential signal pairs or supply rails to absorb repetitive 10/1000 µs transients from IGBT commutation. Use Value: 175 °C junction rating allows mounting on same PCB as power stage without thermal derating, simplifying layout and thermal management. |
| Telecom Base Station Power Input | Consumer Smart Appliance Sensor Hub |
Use Scenario: Guards primary DC input (24–48 V) of remote radio units against lightning-induced surges entering via outdoor cabling. IC Role / Device Role / Timing Role: First-line transient suppressor upstream of DC-DC converters and PMICs, sized for 7 kW peak energy dissipation. Use Value: 7000 W PPPM rating meets ITU-T K.20 and IEC 61000-4-5 Level 4 requirements for telecom infrastructure equipment. | Use Scenario: Safeguards MEMS motion sensor and environmental sensor interfaces in white goods against ESD and relay bounce in control boards. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA), bidirectional TVS placed adjacent to sensor IC pins to avoid signal loading while maintaining EMC immunity. Use Value: Halogen-free, RoHS-compliant M3 suffix meets global regulatory requirements for consumer electronics without compromising surge robustness. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T | Unidirectional; 24 V VWM; 38.9 V VCL at 12.3 A; lower PPPM (400 W) | Limited to single-polarity protection; insufficient for bidirectional signal lines or AC-coupled interfaces | Select only for cost-sensitive, low-energy, unidirectional DC rail protection where clamping voltage margin >15 V is acceptable |
| SMCJ24CA | Bidirectional; 24 V VWM; 38.9 V VCL at 180 A; same SMC package; UL 497B certified | Higher clamping voltage reduces protection margin for modern low-voltage ICs (e.g., 3.3 V logic) | Use when legacy design validation exists for 38.9 V clamping or where thermal budget permits higher VCL-related power dissipation |
Compared with SMAJ24A-E3/57T and SMCJ24CA, the XMC7K24CA-M3/H provides superior protection for low-voltage electronics due to its 24 V clamping ceiling - reducing risk of overvoltage damage without requiring additional series impedance or cascaded protection stages.

FAQ
What is the clamping voltage of XMC7K24CA-M3/H at its rated peak pulse current?
The XMC7K24CA-M3/H clamps to a maximum of 24 V at 180 A peak pulse current with a 10/1000 µs waveform, as specified in the Electrical Characteristics table. This value represents the upper limit of voltage seen by protected circuitry during worst-case surge events and is guaranteed across temperature and production lot variations per Vishay's characterization data.
Is XMC7K24CA-M3/H suitable for automotive applications?
Yes, XMC7K24CA-M3/H is AEC-Q101 qualified and rated for operation from −55 °C to +175 °C, making it suitable for under-hood and body-control module applications. Its bidirectional architecture, low clamping voltage, and MSL Level 1 reflow compatibility align with automotive electronics reliability and manufacturing requirements.
Does XMC7K24CA-M3/H have polarity markings on the package?
No, XMC7K24CA-M3/H is a bidirectional TVS diode and carries no polarity marking on the SMC (DO-214AB) case. The device functions identically regardless of orientation in the circuit, eliminating assembly errors related to polarity misplacement during automated placement.
What is the maximum reverse leakage current for XMC7K24CA-M3/H?
The maximum reverse leakage current for XMC7K24CA-M3/H is 1.0 µA at rated 24 V stand-off voltage and 25 °C junction temperature. This low leakage preserves signal fidelity in high-impedance sensor interfaces and minimizes quiescent power draw in battery-powered systems.
How does XMC7K24CA-M3/H differ from standard SMC-package TVS diodes like SMCJ24CA?
XMC7K24CA-M3/H uses Vishay's XClampR® technology to achieve a clamping voltage of ≤24 V - matching its VWM - whereas SMCJ24CA clamps at 38.9 V. This 15 V reduction significantly improves protection margin for modern low-voltage ICs, especially in automotive and industrial applications where voltage headroom is constrained.
