Product details
Overview
TPSMP24HE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 21.6 V minimum breakdown voltage, 24.3 V maximum clamping voltage at 11.5 A peak pulse current, and 400 W peak pulse power rating for VBR ≥13 V. It delivers low-profile (1.0 mm height), AEC-Q101 qualified protection for sensor signal lines in engine control units.
For engineers reviewing the TPSMP24HE3/84A datasheet, TPSMP24HE3/84A pinout, TPSMP24HE3/84A application, or TPSMP24HE3/84A equivalent, key selection criteria include clamping voltage at rated IPPM, standoff voltage (19.4 V), junction temperature range (–65 °C to +185 °C), and MSL Level 1 reflow compatibility.
Technical Context
This TVS diode uses patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and ISO 7637-2 load-dump transients. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining 19.4 V stand-off capability under normal operation.
The device is optimized for surface-mount automotive applications requiring high power density in minimal board space: it delivers 400 W peak pulse power (10/1000 µs waveform) with only 1.0 mm profile and meets J-STD-020 MSL Level 1 at 260 °C peak reflow temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 21.6 V min / 26.4 V max at 1 mA - defines precise overvoltage triggering threshold for circuit protection |
| Clamping Voltage VC | 34.7 V max at 11.5 A IPPM - limits downstream IC voltage stress during surge events |
| Peak Pulse Power PPPM | 400 W (10/1000 µs) - sustains high-energy transients without failure in automotive environments |
| Stand-off Voltage VWM | 19.4 V - ensures no conduction during normal 12 V system operation with margin |
| Reverse Leakage IR | 1.0 µA max at VWM - minimizes quiescent power loss in always-on sensor circuits |
| Junction Temperature Range | –65 °C to +185 °C - supports under-hood deployment in extreme thermal conditions |
| Package | DO-220AA (SMP) - 1.0 mm height enables ultra-thin PCB designs and automated placement |

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-E3/5AT | DO-214AC (SMA) package; 26.7 V VC at 12.3 A; 400 W PPPM; RoHS-compliant but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial systems with less stringent reliability requirements | Select when AEC-Q101 is not mandated and board space allows larger SMA footprint |
| TPSMP24AHE3/84A | Higher VBR (22.8–25.2 V) and lower VC (33.2 V); same DO-220AA package and AEC-Q101 qualification | Better noise immunity in 24 V systems due to higher standoff (20.5 V) and tighter VBR tolerance | Prefer for 24 V battery architectures where tighter clamping and reduced leakage at elevated VWM are critical |
Compared with SMAJ24A-E3/5AT, TPSMP24HE3/84A offers automotive qualification and 1.0 mm height advantage; compared with TPSMP24AHE3/84A, it trades slightly higher VC for broader VBR tolerance-ideal for cost-sensitive 12 V ECU designs where 34.7 V clamping is acceptable.

FAQ
What is the clamping voltage of the TPSMP24HE3/84A at its rated peak pulse current?
The TPSMP24HE3/84A has a maximum clamping voltage (VC) of 34.7 V at 11.5 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per ANSI/IEEE C62.35 and ensures downstream components remain within safe operating voltage limits during surge events. The TPSMP24HE3/84A achieves this with low incremental surge resistance enabled by its patented PAR oxide passivation.
Is the TPSMP24HE3/84A suitable for 24 V automotive systems?
The TPSMP24HE3/84A is primarily designed for 12 V automotive systems, with a 19.4 V stand-off voltage (VWM) and 21.6–26.4 V breakdown range. For 24 V systems, Vishay recommends the TPSMP24AHE3/84A variant (VWM = 20.5 V, tighter VBR tolerance), which shares the same DO-220AA package and AEC-Q101 qualification as the TPSMP24HE3/84A.
Does the TPSMP24HE3/84A have AEC-Q101 qualification?
Yes, the TPSMP24HE3/84A is explicitly AEC-Q101 qualified, as confirmed in Vishay document 88471 revision 21-Oct-08. This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress test (HAST), making the TPSMP24HE3/84A suitable for under-hood automotive applications where reliability is mission-critical.
What is the maximum operating junction temperature for the TPSMP24HE3/84A?
The TPSMP24HE3/84A has a maximum operating junction temperature (TJ) of +185 °C and a storage temperature range of –65 °C to +185 °C. This wide thermal envelope supports deployment in high-heat zones such as engine compartments and power inverters, where ambient temperatures may exceed 125 °C and require robust thermal derating margins.
How does the DO-220AA package of the TPSMP24HE3/84A compare to standard SMA packages?
The DO-220AA (SMP) package of the TPSMP24HE3/84A measures 1.0 mm in height versus ~2.3 mm for DO-214AC (SMA), offering >50 % height reduction. It maintains comparable thermal performance via optimized copper pad layout (5.0 × 5.0 mm per terminal) and delivers identical 400 W peak pulse power. The TPSMP24HE3/84A's low profile enables thinner ECUs and camera modules without sacrificing surge handling capability.
