Product details
Overview
XMC7K24CA-M3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, featuring 24 V working stand-off voltage, 26.7–29.5 V breakdown voltage, 180 A peak pulse current (10/1000 µs), 24 V max clamping voltage, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the XMC7K24CA-M3/I datasheet, XMC7K24CA-M3/I pinout, XMC7K24CA-M3/I application, or XMC7K24CA-M3/I equivalent, this device serves as a high-energy, low-clamping protection solution for sensitive signal lines and power rails in harsh thermal and transient environments - especially where TJ = 175 °C operation and UL 497B safety recognition are required.
Technical Context
The XMC7K24CA-M3/I employs Vishay's XClampR® technology to achieve extremely low clamping voltage (≤24 V at 180 A), enabling robust protection of downstream ICs and MOSFETs against inductive switching transients and lightning-induced surges. Its bidirectional architecture supports AC-coupled and symmetrical signal line protection without polarity concerns.
Rated for continuous operation from –55 °C to +175 °C junction temperature and qualified per AEC-Q101, the device sustains performance under automotive under-hood thermal stress while maintaining <1.0 µA reverse leakage at 24 V and meeting MSL Level 1 reflow compatibility (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - Maximum DC or RMS voltage the device blocks continuously without conduction |
| VBR (min/max) | 26.7 V / 29.5 V - Breakdown occurs within this range at 1.0 mA test current, defining turn-on threshold tolerance |
| VCL (max) | 24 V - Clamped voltage seen by protected circuit during 180 A 10/1000 µs surge, limiting stress on downstream components |
| IPPM | 180 A - Peak surge current capability with standard 10/1000 µs waveform, supporting 7 kW pulse power rating |
| TJ max | +175 °C - Enables placement near high-temperature sources (e.g., engine control units) without derating loss |
| Polarity | Bidirectional - Protects both positive and negative transients on same line; no polarity marking required |
| IR (max) | 1.0 µA - Ultra-low leakage ensures minimal loading on high-impedance sensor or communication lines |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL Level 1, matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (unmarked end) | Anode/Cathode terminal pair | Bidirectional structure - either end may serve as anode or cathode depending on transient polarity; no polarity marking on body |
| Anode (unmarked end) | Anode/Cathode terminal pair | Identical physical terminal; conduction path forms symmetrically across junction during ±V transients |
Key Features
| Feature | Design Value |
|---|---|
| XClampR® low clamping | Clamps ≤24 V at 180 A - reduces voltage overshoot below IC absolute maximum ratings, minimizing risk of latch-up or gate oxide damage |
| AEC-Q101 qualification | Validated for automotive applications including powertrain and ADAS - ensures reliability under temperature cycling, mechanical shock, and humidity stress |
| UL 497B recognition | File E136766 - certifies suitability for primary-side telecom and industrial signal line protection per safety standards |
| High-temperature operation | Junction range –55 °C to +175 °C - eliminates need for thermal derating in under-hood or industrial motor drive environments |
| Low leakage current | ≤1.0 µA at VWM - preserves signal integrity on high-Z sensor outputs and precision analog interfaces |
Applications
| Automotive Powertrain ECUs | Industrial Sensor Signal Lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/5AT | Unidirectional; 24 V VWM; 38.9 V VBR min; 38.9 V VCL max at 12.3 A; lower IPPM (12.3 A) | Requires external polarity management; insufficient for 180 A surge events | Select only for low-energy, cost-sensitive consumer applications where bidirectionality and high IPPM are not required |
| SMCJ24CA | Bidirectional; 24 V VWM; 26.7–29.5 V VBR; 38.9 V VCL max at 180 A; same package; no AEC-Q101 or UL 497B | Lacks automotive qualification and safety certification; higher clamping degrades protection margin | Acceptable for industrial non-safety-critical use when AEC-Q101 and UL recognition are not mandated |
Compared with SMAJ24A-E3/5AT and SMCJ24CA, the XMC7K24CA-M3/I delivers superior protection margin via 24 V clamping at full 180 A, plus AEC-Q101 and UL 497B compliance - making it the only choice for automotive and telecom safety-critical designs requiring verified high-reliability surge response.

FAQ
What is the clamping voltage of the XMC7K24CA-M3/I at its rated peak pulse current?
The XMC7K24CA-M3/I clamps to a maximum of 24 V at 180 A peak pulse current with a 10/1000 µs waveform. This value is guaranteed across temperature and represents the upper limit of voltage imposed on protected circuitry during worst-case surge events - critical for ensuring downstream ICs remain within absolute maximum ratings. The XMC7K24CA-M3/I achieves this via XClampR® junction design optimized for low dynamic impedance.
Is the XMC7K24CA-M3/I suitable for automotive applications?
Yes, the XMC7K24CA-M3/I is AEC-Q101 qualified and rated for junction temperatures up to +175 °C, making it suitable for under-hood and powertrain applications. Its SMC package meets MSL Level 1 reflow requirements, and the device carries UL 497B safety recognition (file E136766). These attributes confirm the XMC7K24CA-M3/I meets key automotive reliability and safety benchmarks beyond basic parametric compliance.
Does the XMC7K24CA-M3/I have polarity markings?
No, the XMC7K24CA-M3/I is a bidirectional TVS and carries no polarity marking on the SMC package body. Both terminals are functionally identical - conduction occurs symmetrically for positive and negative transients. This simplifies PCB layout and eliminates orientation errors during automated assembly. The XMC7K24CA-M3/I's bidirectional behavior is intrinsic to its internal junction structure, not achieved via back-to-back die.
What is the reverse leakage current specification for the XMC7K24CA-M3/I?
The XMC7K24CA-M3/I exhibits a maximum reverse leakage current of 1.0 µA at its rated 24 V working stand-off voltage and TJ = 25 °C. This ultra-low leakage ensures minimal loading on high-impedance nodes such as sensor outputs, analog front-ends, and communication line receivers. The XMC7K24CA-M3/I maintains tight leakage control across its full operating temperature range, supporting precision signal integrity.
How does the XMC7K24CA-M3/I differ from standard SMC-package TVS diodes like SMCJ24CA?
The XMC7K24CA-M3/I differs from SMCJ24CA primarily in clamping performance (24 V vs. 38.9 V at 180 A), AEC-Q101 qualification, and UL 497B safety recognition. While both share the SMC (DO-214AB) package and 24 V VWM, the XMC7K24CA-M3/I's XClampR® technology enables significantly lower dynamic impedance. This makes the XMC7K24CA-M3/I appropriate for protecting modern low-voltage ICs where tighter clamping margins are mandatory.
