Product details
Overview
TPSMA24HE3/61T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 24 V nominal breakdown voltage (VBR = 22.8–25.2 V), 400 W peak pulse power (10/1000 µs), 33.2 V maximum clamping voltage at 12 A, 1.0 W steady-state power dissipation, and operates up to TJ = 185 °C - suitable for automotive ECUs and industrial sensor protection.
For engineers reviewing the TPSMA24HE3/61T datasheet, TPSMA24HE3/61T pinout, TPSMA24HE3/61T application, or TPSMA24HE3/61T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (via HE3 suffix), MSL Level 1 rating, 185 °C junction capability, and verified clamping performance under 10/1000 µs surge conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and excellent clamping response. Its unidirectional architecture provides fast turn-on during positive-going transients while blocking reverse leakage below 1.0 µA at 20.5 V stand-off voltage.
Designed for high-reliability environments, TPSMA24HE3/61T supports operation from –65 °C to +185 °C and meets JESD201 Class 2 whisker resistance. The device is qualified per AEC-Q101 and rated for repetitive 400 W pulses at 0.01 % duty cycle with derating above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 22.8 V / 24.0 V / 25.2 V - ensures reliable conduction onset above system operating voltage while avoiding false triggering |
| VWM | 20.5 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 33.2 V at 12.0 A - clamping voltage limits downstream IC stress during 10/1000 µs surges |
| PPPM | 400 W - peak surge power handling capability under standardized lightning/inductive-switching waveforms |
| TJ max. | +185 °C - enables use in under-hood automotive and high-temperature industrial PCB layouts |
| Polarity | Unidirectional - protects against positive transients only; cathode band denotes terminal orientation |
| Package | SMA (DO-214AC) - surface-mount footprint compatible with standard reflow profiles and MSL Level 1 handling |
Pinout & Package
TPSMA24HE3/61T is housed in an SMA (DO-214AC) plastic package with matte tin-plated leads. Cathode is marked by a color band; terminals are solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode of internal PN junction | Connected to protected line; conducts when transient exceeds VBR, shunting current to ground |
| Anode | Cathode of internal PN junction | Typically tied to system ground; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| 185 °C junction rating | Enables placement near heat sources (e.g., power MOSFETs, DC-DC converters) without thermal derating penalties |
| 400 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV) surge events when properly mounted on 5 mm × 5 mm copper pads |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes voltage overshoot across protected ICs, reducing risk of latch-up or gate oxide damage |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow processing without baking preconditioning |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protects microcontroller GPIO and CAN transceiver power rails from load-dump and alternator ripple transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between supply rail and ground, activated within <1 ns of overvoltage onset. Use Value: Limits transient voltage to ≤33.2 V, preventing damage to 3.3 V/5 V logic interfaces and ensuring ASIL-B functional safety compliance. | Use Scenario: Shields 24 V digital input circuitry from inductive kickback generated by solenoid valves and relay coils in factory automation. IC Role / Device Role / Timing Role: Standoff protector on field-side input traces, conducting only during >20.5 V excursions to divert surge energy away from optocoupler inputs. Use Value: Maintains <1.0 µA leakage at 20.5 V, preserving input threshold accuracy while surviving repeated 40 A surge events per IEC 61000-4-4. |
| Telecom Power Supply Front-End | Consumer Appliance Motor Drive Board |
Use Scenario: Guards AC-DC converter primary-side bias rails against lightning-induced surges entering via mains input. IC Role / Device Role / Timing Role: Secondary-level transient suppressor located after MOV but before controller IC, providing precise clamping where MOV tolerance is insufficient. Use Value: Delivers tighter VC tolerance (±0.3 V) than generic MOVs, enabling smaller downstream capacitor sizing and improved hold-up time margin. | Use Scenario: Safeguards BLDC motor gate driver ICs from back-EMF spikes during commutation in smart washing machines and HVAC fans. IC Role / Device Role / Timing Role: Localized clamp on half-bridge high-side and low-side supply pins, placed adjacent to driver ICs to minimize loop inductance. Use Value: Withstands 8.3 ms half-sine surges up to 40 A (IFSM), eliminating need for redundant parallel TVS devices in compact motor control layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Same VBR range (22.8–25.2 V), but SMB package (DO-214AA); 600 W PPPM; higher thermal mass | Requires larger PCB pad area; better suited for higher-energy surges but less space-efficient | Select SMBJ24A when board layout allows larger footprint and surge energy exceeds 400 W |
| 1.5SMC24A | Same VBR, but SMC package (DO-214AB); 1500 W PPPM; higher IPPM (65.1 A) | Designed for primary-side surge suppression; not AEC-Q101 qualified; RoHS-compliant only | Choose 1.5SMC24A for non-automotive, high-energy front-end protection where AEC-Q101 is not required |
Compared with SMBJ24A and 1.5SMC24A, TPSMA24HE3/61T offers the smallest footprint (SMA), AEC-Q101 qualification, and optimized thermal performance for high-density automotive modules - making it preferred for space-constrained, safety-critical designs requiring validated reliability.

FAQ
What is the exact breakdown voltage range for TPSMA24HE3/61T?
The TPSMA24HE3/61T has a guaranteed breakdown voltage range of 22.8 V (minimum) to 25.2 V (maximum) at 1.0 mA test current, with a typical value of 24.0 V. This specification is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 23-Jan-2024 (Document Number: 88405). The device maintains this VBR stability across its full operating temperature range.
Is TPSMA24HE3/61T AEC-Q101 qualified?
Yes, TPSMA24HE3/61T is AEC-Q101 qualified. The "HE3" suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified construction, as stated in the Vishay ordering information and mechanical data sections. This qualification covers stress tests including HTGB, HTRB, temperature cycling, and ESD, validating its suitability for automotive electronic control units.
What is the maximum clamping voltage of TPSMA24HE3/61T and at what current is it specified?
The maximum clamping voltage (VC) of TPSMA24HE3/61T is 33.2 V, measured at a peak pulse current (IPPM) of 12.0 A using the standardized 10/1000 µs waveform. This value is guaranteed across all production lots and is critical for determining safe voltage margins for downstream ICs protected by the TPSMA24HE3/61T.
Does TPSMA24HE3/61T have unidirectional or bidirectional polarity?
TPSMA24HE3/61T is unidirectional only. As confirmed in the Vishay datasheet features section, it is designed to clamp positive transients relative to ground and does not conduct in reverse bias beyond its specified leakage current. Polarity is indicated by a cathode band on the SMA package body.
What is the package type and moisture sensitivity level (MSL) of TPSMA24HE3/61T?
TPSMA24HE3/61T uses the SMA (DO-214AC) surface-mount package and meets MSL Level 1 per J-STD-020, with a maximum lead-free reflow peak temperature of 260 °C. This allows indefinite floor life and eliminates the need for baking prior to assembly - a key advantage for high-throughput manufacturing of TPSMA24HE3/61T-based designs.
