Product details
Overview
TPSMC30AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features a 30 V nominal breakdown voltage (VBR), 25.6 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 36.2 A peak pulse current (IPPM), and 41.4 V maximum clamping voltage (VC) - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power rails.
For engineers reviewing the TPSMC30AHE3/57T datasheet, TPSMC30AHE3/57T pinout, TPSMC30AHE3/57T application, or TPSMC30AHE3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, low incremental surge resistance, and compatibility with high-reliability PCB layouts requiring MSL Level 1 reflow.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by overvoltage events such as inductive load switching or ESD. Its passivated anisotropic rectifier structure enables fast response time (<1 ns), low leakage (<1 µA at VWM), and stable clamping performance across -65 °C to +185 °C operating range.
The device is optimized for single-pulse transient suppression per IEC 61000-4-5 and ANSI/IEEE C62.35 standards, with thermal derating above 25 °C per Fig. 2 and tested under 8.3 ms half-sine surge conditions up to 200 A (IFSM). Its SMC package supports high-power dissipation via 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 28.5 / 30.0 / 31.5 V - defines precise voltage threshold at which avalanche conduction begins under 1 mA test current |
| VWM | 25.6 V - maximum continuous reverse working voltage before leakage exceeds 1 µA, ensuring no false triggering during normal operation |
| VC @ IPPM | 41.4 V - clamped voltage seen by protected circuit during 36.2 A transient, limiting stress on downstream components |
| PPPM | 1500 W - peak pulse power handling capability with 10/1000 µs waveform, enabling robust surge immunity |
| TJ max. | +185 °C - extended junction temperature rating supports under-hood automotive and high-ambient industrial environments |
| Polarity | Unidirectional - cathode-banded configuration protects only against positive transients relative to anode |
| MSL Level | Level 1 (J-STD-020) - allows unlimited floor life and standard reflow without baking preconditioning |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, 0.320" × 0.246" footprint (8.13 mm × 6.22 mm), cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to system ground or lower-potential rail; forms return path during clamping |
| Cathode | Transient input node | Connected to line being protected (e.g., 24 V supply rail); conducts avalanche current when VAK > VBR |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Lower peak pulse power (400 W), smaller SMA package, same VBR and VC tolerance but higher clamping ratio | Not qualified to AEC-Q101; limited to commercial-temperature industrial use | Select when cost and board space are critical and automotive qualification is not required |
| 1.5KE30A | Through-hole DO-201 package, 1500 W rating, but larger footprint and incompatible with SMT assembly | Lacks MSL Level 1 rating and JESD201 whisker testing; unsuitable for high-volume automated manufacturing | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not needed |
Compared with SMAJ30A and 1.5KE30A, the TPSMC30AHE3/57T delivers automotive-grade reliability in a surface-mount form factor with superior thermal robustness (TJ = 185 °C) and zero reflow restrictions - making it optimal for production-grade automotive and industrial systems demanding long-term field stability.

FAQ
What is the breakdown voltage tolerance of the TPSMC30AHE3/57T?
The TPSMC30AHE3/57T has a guaranteed breakdown voltage range of 28.5 V (minimum) to 31.5 V (maximum) at 1 mA test current, with 30.0 V as the nominal value. This ±5% tolerance ensures consistent clamping behavior across production lots and supports reliable design margining in 24 V system protection circuits where the TPSMC30AHE3/57T is commonly deployed.
Is the TPSMC30AHE3/57T RoHS-compliant and halogen-free?
Yes, the TPSMC30AHE3/57T carries the HE3 suffix, indicating it is RoHS-compliant and AEC-Q101 qualified. However, it is not halogen-free - that designation applies only to HM3-suffix variants. The HE3 version uses standard molding compound meeting UL 94 V-0 and passes JESD201 Class 2 whisker testing, making it suitable for automotive and industrial applications requiring regulatory compliance without halogen-free requirement.
What is the maximum clamping voltage of the TPSMC30AHE3/57T under surge conditions?
The TPSMC30AHE3/57T exhibits a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current of 36.2 A using the standardized 10/1000 µs waveform. This value is measured at the device terminals and represents the upper limit of voltage imposed on the protected circuit during worst-case transient events, directly informing safe operating area calculations for downstream ICs powered from the same rail as the TPSMC30AHE3/57T.
Can the TPSMC30AHE3/57T be used in bidirectional configurations?
No, the TPSMC30AHE3/57T is unidirectional only, as confirmed in the Vishay datasheet. Its internal structure and cathode-band marking indicate polarity-sensitive operation - it conducts only when the cathode is at a higher potential than the anode. For bidirectional protection, two TPSMC30AHE3/57T devices must be connected in series opposition, or a dedicated bidirectional TVS such as the TPSMC30CA should be selected instead.
What is the thermal derating behavior of the TPSMC30AHE3/57T above 25 °C ambient?
The TPSMC30AHE3/57T follows the derating curve shown in Figure 2 of its datasheet: peak pulse power decreases linearly from 100% at 25 °C to approximately 50% at 125 °C, and further to ~20% at 175 °C. This behavior is due to reduced thermal headroom for energy dissipation and must be accounted for in high-ambient designs - for example, a 24 V automotive module operating at 105 °C ambient may require derated surge margin or additional thermal relief near the TPSMC30AHE3/57T mounting pads.
