Product details
Overview
SMA5J24CHE3/61 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on signal and power lines. It features a 24 V stand-off voltage (VWM), 38.9 V maximum clamping voltage (VC) at 12.9 A peak pulse current (IPPM), 500 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMA5J24CHE3/61 datasheet, SMA5J24CHE3/61 pinout, SMA5J24CHE3/61 application, or SMA5J24CHE3/61 equivalent, key selection criteria include bi-directional clamping performance, junction temperature rating up to +150 °C, RoHS-compliant matte tin plating, MSL Level 1 handling, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bi-directional TVS diode operates symmetrically in both reverse and forward directions, with breakdown voltage (VBR) specified between 26.7 V and 29.5 V at 1 mA test current. Its low incremental surge resistance and fast response time enable effective suppression of ESD, lightning-induced transients, and inductive switching spikes.
The device uses a glass-passivated silicon junction and is rated for non-repetitive peak pulse power of 500 W under standard 10/1000 µs waveform conditions. Thermal resistance is 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), supporting reliable operation in compact automotive and industrial PCB layouts.
Key Specifications

|---|---|
| VWM | 24 V - Maximum continuous reverse stand-off voltage before clamping begins; defines operating margin for protected circuitry. |
| VC @ IPPM | 38.9 V - Clamped voltage at 12.9 A peak pulse current; determines maximum stress imposed on downstream ICs during surge. |
| PPPM | 500 W - Peak pulse power handling capability under 10/1000 µs waveform; enables robust protection against IEC 61000-4-5 surges. |
| VBR min/max | 26.7 V / 29.5 V - Breakdown voltage range at 1 mA; ensures consistent triggering across production lots and temperature. |

| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per AEC specification. |
Pinout & Package
DO-214AC (SMA) package: bi-directional device with no polarity marking; two terminals-cathode/anode are functionally interchangeable. Leads are matte tin plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge current entry (reverse bias) | Accepts transient energy from either direction; no fixed polarity due to bi-directional symmetry. |
| Cathode | Surge current entry (forward bias) | Functions identically to anode under reverse surge; terminal designation is nominal only. |

|---|---|
| Bi-directional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns. |
| 500 W peak pulse power | Supports compliance with IEC 61000-4-5 Level 4 (4 kV line-to-line, 2 kV line-to-ground) when properly mounted. |
| Glass-passivated junction | Ensures stable leakage current (<1.0 µA at VWM) and long-term reliability under thermal cycling. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking; simplifies SMT manufacturing flow. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules requiring zero-defect reliability. |
Applications
| Automotive CAN Bus Protection | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L differential pair in vehicle ECUs against load dump and ESD events. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed directly at connector interface to limit transients to <40 V. Use Value: Prevents damage to CAN transceivers (e.g., TJA1042) by clamping surges within safe input voltage range while maintaining signal integrity. | Use Scenario: Shielding 4–20 mA analog sensor outputs in factory automation systems from motor drive noise. IC Role / Device Role / Timing Role: Transient suppressor installed across output terminals to absorb inductive kickback from solenoid valves. Use Value: Maintains loop accuracy by limiting voltage excursions to ≤38.9 V, avoiding ADC saturation or op-amp rail-to-rail clipping. |
| Telecom DSL Line Interface | Consumer USB Port ESD Protection |
Use Scenario: Safeguarding ADSL/VDSL line drivers and receivers from lightning-induced surges on twisted-pair copper lines. IC Role / Device Role / Timing Role: Primary surge arrestor on line side of isolation transformer, rated for repeated 500 W pulses. Use Value: Extends service life of line interface ICs (e.g., LME49710) by absorbing >95% of surge energy before it reaches active components. | Use Scenario: Adding secondary-level ESD protection on USB 2.0 D+/D− lines behind integrated port protectors. IC Role / Device Role / Timing Role: Fast-response bi-directional clamp suppressing ±15 kV contact discharge per IEC 61000-4-2. Use Value: Reduces failure rate in portable devices by limiting transient overshoot to <39 V, well below USB PHY absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J24CA-E3/61 | Same electrical specs and DO-214AC package; commercial-grade (non-AEC-Q101) version with identical VWM, VC, and PPPM. | Approved for industrial/commercial use only; not validated for automotive temperature cycling or lifetime reliability testing. | Select when AEC-Q101 qualification is not required and cost optimization is prioritized. |
| SMCJ24CAHE3/61 | Higher power rating (1500 W), larger DO-214AB (SMC) package (7.11 mm × 6.22 mm), same 24 V VWM and bi-directional configuration. | Used where higher surge energy (e.g., 10/1000 µs 100 A pulses) must be absorbed without derating or parallel devices. | Choose when system-level surge tests exceed 500 W or board space allows larger footprint for enhanced thermal margin. |
Compared with SMA5J24CHE3/61, SMA5J24CA-E3/61 offers identical protection performance at lower qualification cost, while SMCJ24CAHE3/61 trades smaller size for 3× higher pulse power - enabling design flexibility between miniaturization and extreme surge resilience.

FAQ
What is the clamping voltage of the SMA5J24CHE3/61 under a 10/1000 µs surge?
The SMA5J24CHE3/61 clamps to a maximum of 38.9 V when subjected to its rated peak pulse current of 12.9 A under the standard 10/1000 µs waveform. This value is measured at the device terminals with recommended PCB pad layout (0.2" × 0.2" copper per terminal) and represents the upper voltage limit imposed on protected circuitry during surge events.
Is the SMA5J24CHE3/61 suitable for automotive applications?
Yes, the SMA5J24CHE3/61 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junctions, matte tin-plated leads compliant with JESD 201 Class 2 whisker testing, and guaranteed operation from −55 °C to +150 °C - meeting requirements for engine control units, body electronics, and ADAS subsystems.
Does the SMA5J24CHE3/61 have polarity markings?
No, the SMA5J24CHE3/61 is a bi-directional TVS diode and carries no polarity marking on the DO-214AC (SMA) package. Unlike uni-directional variants (e.g., SMA5J24A), it functions identically regardless of orientation on the PCB, simplifying layout and assembly for AC or floating signal paths.
What is the maximum leakage current of the SMA5J24CHE3/61 at its stand-off voltage?
At its 24 V stand-off voltage (VWM), the SMA5J24CHE3/61 exhibits a maximum reverse leakage current (ID) of 1.0 µA at 25 °C. This low leakage ensures minimal power loss and avoids interference with high-impedance sensor or communication circuits during normal operation.
Can the SMA5J24CHE3/61 be used in parallel for higher surge current handling?
Parallel use of SMA5J24CHE3/61 devices is not recommended without careful derating and matching. Variations in VBR tolerance (26.7–29.5 V) and dynamic impedance can cause uneven current sharing. For higher surge capacity, select a single higher-rated device such as SMCJ24CAHE3/61 rather than paralleling multiple SMA5J24CHE3/61 units.
