Overview
TPSMB24A801HE3/5BT from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 24.0 V nominal breakdown voltage (VBR), 20.5 V stand-off voltage (VWM), 33.2 V maximum clamping voltage (VC) at 18.1 A peak pulse current, 600 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - deployed in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMB24A801HE3/5BT datasheet, TPSMB24A801HE3/5BT pinout, TPSMB24A801HE3/5BT application, or TPSMB24A801HE3/5BT equivalent, this page delivers verified electrical parameters, SMB (DO-214AA) package mapping, AEC-Q101 qualification status, thermal derating behavior, and direct alternative part comparisons grounded in Vishay's official specifications.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and excellent clamping linearity under repetitive 10/1000 µs transients. Its unidirectional polarity and cathode-band marking align with standard SMB layout conventions, enabling straightforward integration into DC-biased protection paths.
The device is rated for 75 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), exhibits 0.085 %/°C temperature coefficient of VBR, and maintains stable performance across -65 °C to +185 °C operating junction range - meeting high-reliability requirements for under-hood automotive electronics and industrial control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 22.8 V / 24.0 V / 25.2 V - defines precise voltage threshold where avalanche conduction begins; ensures reliable triggering before downstream IC damage. |
| VWM | 20.5 V - maximum continuous reverse working voltage; sets safe DC operating margin below breakdown. |
| VC @ IPPM | 33.2 V at 18.1 A - clamped voltage during 10/1000 µs surge; determines worst-case overvoltage seen by protected circuitry. |
| PPPM | 600 W - peak pulse power handling capability; supports robust protection against ISO 7637-2 Pulse 1/2a/5a transients. |
| TJ max. | +185 °C - enables placement near hot components (e.g., power MOSFETs, DC-DC converters) without derating loss. |
| IR @ VWM | 1 µA - ultra-low leakage at stand-off voltage; avoids parasitic loading on high-impedance sensor or reference lines. |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 0.205" × 0.220" footprint; compatible with automated pick-and-place and reflow. |

Use Scenario: Suppressing back-EMF spikes from brushed DC motors in smart home appliances (e.g., washing machine pumps). IC Role / Device Role / Timing Role: TVS placed across motor terminals (cathode to +V, anode to GND) to clamp inductive turn-off spikes. Use Value: 75 A IFSM withstands repeated motor stall currents; SMB footprint allows compact placement adjacent to motor driver IC. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Same SMB package, identical VBR/VC specs, but not AEC-Q101 qualified; 150 °C TJ max. | Lacks automotive qualification; suitable only for industrial/commercial use where extended temperature is not required. | Select SMBJ24A only if AEC-Q101 compliance and 185 °C operation are unnecessary - lower cost, same footprint. |
| TPSMB24AHM3 | Identical electrical specs and AEC-Q101 qualification; halogen-free molding compound (vs. RoHS-only HE3). | Required for strict environmental compliance (e.g., EU automotive Tier 1 programs mandating halogen-free materials). | Choose TPSMB24AHM3 when halogen-free material compliance is mandated - same thermal and electrical performance as TPSMB24A801HE3/5BT. |
Compared with SMBJ24A and TPSMB24AHM3, the TPSMB24A801HE3/5BT provides full AEC-Q101 qualification and RoHS compliance in the SMB package, making it the default choice for automotive designs requiring both reliability validation and regulatory alignment - while TPSMB24AHM3 adds halogen-free assurance without trade-offs.

FAQ
What is the exact breakdown voltage tolerance for TPSMB24A801HE3/5BT?
The TPSMB24A801HE3/5BT has a guaranteed breakdown voltage range of 22.8 V (minimum) to 25.2 V (maximum) at 1 mA test current, with 24.0 V nominal. This ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 24 V systems where overvoltage margins are tight.
Is TPSMB24A801HE3/5BT qualified to AEC-Q101?
Yes, TPSMB24A801HE3/5BT is AEC-Q101 qualified - confirmed by Vishay's official documentation and ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101 qualified variants. This qualification covers stress tests including HTGB, H3TRB, and temperature cycling, validating suitability for automotive powertrain and chassis applications.
What does the "801" in TPSMB24A801HE3/5BT signify?
The "801" in TPSMB24A801HE3/5BT is a revision code denoting the specific manufacturing lot or process iteration - consistent with Vishay's naming convention where "_X" (e.g., A, B, 801) indicates revision level. It does not affect electrical specifications or package dimensions; all TPSMB24A variants share identical VBR, VC, and thermal ratings.
Can TPSMB24A801HE3/5BT be used in bidirectional configurations?
No, TPSMB24A801HE3/5BT is unidirectional only, as explicitly stated in Vishay's datasheet. It conducts avalanche current only when cathode voltage exceeds anode by ≥VBR. For bidirectional protection (e.g., AC lines or differential data buses), a separate dual-diode configuration or dedicated bidirectional TVS like SMBJ24CA must be used.
What is the maximum clamping voltage of TPSMB24A801HE3/5BT under surge conditions?
The maximum clamping voltage (VC) of TPSMB24A801HE3/5BT is 33.2 V at 18.1 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and represents the worst-case voltage imposed on protected circuitry during standardized surge events - essential for verifying margin against downstream IC absolute maximum ratings.
