Product details
Overview
TPSMC30AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, featuring 30 V breakdown voltage (VBR = 28.5–31.5 V), 25.6 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 μs), and 185 °C maximum junction temperature - deployed for robust overvoltage protection of automotive power rails and industrial sensor signal lines.
For engineers reviewing the TPSMC30AHE3_B/H datasheet, TPSMC30AHE3_B/H pinout, TPSMC30AHE3_B/H application, or TPSMC30AHE3_B/H equivalent, key selection criteria include clamping voltage (41.4 V at 36.2 A), low leakage (<1.0 μA at VWM), AEC-Q101 qualification, MSL Level 1 rating, and unidirectional polarity with cathode band marking.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge stress, with thermal derating validated up to 185 °C junction temperature. Its 10/1000 μs waveform response supports IEC 61000-4-5 compliance in harsh environments.
The device operates exclusively in unidirectional mode, with forward voltage limited to 3.5 V at 100 A and surge current capability of 200 A (8.3 ms half-sine). It meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements for high-reliability PCB mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 28.5 / 30.0 / 31.5 V - ensures reliable triggering above system operating voltage while avoiding false trips during transients |
| VWM | 25.6 V - defines maximum continuous reverse voltage before leakage exceeds 1.0 μA, matching 24 V automotive rail systems |
| VC @ IPPM | 41.4 V - clamping voltage at 36.2 A peak pulse current, limiting downstream IC stress during ESD or load dump events |
| PPPM | 1500 W - peak pulse power handling per 10/1000 μs waveform, enabling protection against ISO 7637-2 Pulse 1 & 2a/b |
| TJ max | +185 °C - enables operation in under-hood automotive locations and high-temperature industrial enclosures without derating |
| Leakage @ VWM | <1.0 μA - minimizes standby power loss and avoids interference in high-impedance sensor bias networks |
| AEC-Q101 | Qualified - certified for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated leads, RoHS-compliant and halogen-free (HE3 suffix), MSL Level 1, 260 °C reflow compatible.

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 24 V supply lines in body control modules against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between VBAT and chassis ground to clamp transients above 25.6 V. Use Value: Limits clamping voltage to 41.4 V at 36.2 A, preventing damage to downstream PMICs and microcontrollers rated for 42 V absolute max. |
Use Scenario: Shielding analog outputs of pressure/temperature sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: TVS placed across differential signal pair (e.g., 4–20 mA loop) to absorb EFT bursts and cable discharge events. Use Value: Sub-1 μA leakage at 25.6 V preserves signal accuracy; 185 °C rating ensures stability near hot-running motor controllers. |
| Telecom DC Power Input Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Safeguarding 48 V PoE-powered network switches against lightning-induced surges on DC input. IC Role / Device Role / Timing Role: Primary TVS on front-end DC bus, coordinated with upstream fuse and secondary filtering. Use Value: 1500 W pulse rating handles multi-kV induced transients; MSL Level 1 allows standard SMT assembly without moisture sensitivity concerns. |
Use Scenario: Suppressing inductive kickback from brushed DC motors in smart home appliances (e.g., vacuum cleaners, washing machines). IC Role / Device Role / Timing Role: Mounted across motor terminals to divert flyback energy during MOSFET turn-off. Use Value: Fast response time and low clamping voltage reduce MOSFET VDS stress, extending switching device lifetime and reducing thermal design margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30AHE3_A/H | Lower peak pulse power (600 W), same VBR range and SMC-compatible SMB (DO-214AA) package | Rated for lighter-duty consumer electronics; insufficient for ISO 7637-2 Pulse 5a load dump | Select when space-constrained layouts require smaller footprint and surge energy is ≤600 W |
| TPSMC30AHM3_B/H | Identical electrical specs; HM3 suffix denotes halogen-free construction (vs. HE3's RoHS-only) | Required for strict environmental compliance in EU medical or aerospace programs mandating halogen-free materials | Choose HM3 if halogen-free certification is mandatory; otherwise HE3 offers full functional equivalence |
Compared with SMBJ30AHE3_A/H and TPSMC30AHM3_B/H, the TPSMC30AHE3_B/H delivers higher surge robustness (1500 W vs. 600 W) and identical AEC-Q101 qualification, making it the preferred choice for automotive and industrial-grade 24 V systems where reliability under extreme transients is non-negotiable.

FAQ
What is the clamping voltage of the TPSMC30AHE3_B/H and how is it measured?
The TPSMC30AHE3_B/H has a maximum clamping voltage (VC) of 41.4 V, measured at its peak pulse current (IPPM) of 36.2 A using a 10/1000 μs waveform per Figure 3 in the datasheet. This value reflects the actual voltage seen by protected circuitry during worst-case surge events and is critical for ensuring downstream components remain within their absolute maximum ratings. The TPSMC30AHE3_B/H achieves this clamping performance while maintaining low incremental surge resistance.
Is the TPSMC30AHE3_B/H suitable for automotive applications?
Yes, the TPSMC30AHE3_B/H is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature, making it suitable for under-hood and powertrain-related automotive applications. Its 25.6 V stand-off voltage aligns with 24 V battery systems, and its 1500 W peak pulse power supports ISO 7637-2 Pulse 5a load dump protection. The HE3 suffix confirms RoHS compliance and qualification per the AEC-Q101 standard - all verified in Vishay Document Number 88407.
What does the "HE3" suffix mean in TPSMC30AHE3_B/H?
The "HE3" suffix in TPSMC30AHE3_B/H indicates RoHS-compliant construction with AEC-Q101 qualification, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and JESD 201 Class 2 whisker resistance. It distinguishes this variant from HM3 (halogen-free + RoHS + AEC-Q101) and non-qualified base parts. The "B/H" denotes packaging: 7-inch tape-and-reel with 850 units per reel, per Vishay's ordering information table.
How does the TPSMC30AHE3_B/H compare to the SMBJ30AHE3_A/H in terms of surge capability?
The TPSMC30AHE3_B/H provides 1500 W peak pulse power (10/1000 μs), more than double the 600 W rating of the SMBJ30AHE3_A/H. Both share the same 30 V nominal breakdown voltage, but the TPSMC30AHE3_B/H's larger SMC (DO-214AB) package enables higher energy absorption and superior thermal dissipation. This makes the TPSMC30AHE3_B/H appropriate for heavy-duty applications like automotive load dump, whereas SMBJ30AHE3_A/H suits lower-energy consumer electronics.
What is the maximum leakage current specification for the TPSMC30AHE3_B/H at its stand-off voltage?
The TPSMC30AHE3_B/H specifies a maximum reverse leakage current (IR) of 1.0 μA at its 25.6 V stand-off voltage (VWM) and 25 °C ambient temperature. At elevated temperatures (e.g., 150 °C), leakage remains ≤10 μA - a value confirmed in the Electrical Characteristics table of Vishay Document 88407. This ultra-low leakage preserves signal integrity in high-impedance sensor circuits and minimizes standby power loss in always-on automotive modules.
