Product details
Overview
TPSMC30AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping inductive switching transients and lightning-induced surges. It features 30 V breakdown voltage (VBR = 28.5–31.5 V at 1 mA), 25.6 V stand-off voltage (VWM), 41.4 V maximum clamping voltage (VC) at 36.2 A peak pulse current, and 1500 W peak pulse power (10/1000 µs). It is used to protect MOSFETs, ICs, and sensor signal lines in automotive powertrain control units.
For engineers reviewing the TPSMC30AHE3_A/I datasheet, TPSMC30AHE3_A/I pinout, TPSMC30AHE3_A/I application, or TPSMC30AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, low incremental surge resistance, and compatibility with high-reliability automotive PCB layouts requiring MSL Level 1 reflow.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to achieve stable breakdown characteristics across temperature and lifetime. Its junction passivation enables operation up to TJ = 185 °C and meets AEC-Q101 stress test requirements for automotive under-hood applications.
The device delivers consistent clamping performance under 10/1000 µs surge waveforms with minimal voltage overshoot. Its low dynamic impedance ensures rapid response (<1 ns) and effective suppression of fast-rising transients on power rails and signal lines without compromising system timing integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 28.5 V / 30.0 V / 31.5 V at 1 mA - defines precise voltage threshold where avalanche conduction begins |
| VWM | 25.6 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 41.4 V at 36.2 A - clamped voltage during 1500 W surge, limiting downstream component stress |
| PPPM | 1500 W (10/1000 µs) - peak transient energy absorption capability without failure |
| TJ max. | +185 °C - enables placement near hot components (e.g., power converters) without derating |
| Polarity | Unidirectional - protects against positive-going transients only; cathode band denotes polarity |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 8.0 mm × 8.0 mm copper pad requirement |
Pinout & Package
TPSMC30AHE3_A/I uses the SMC (DO-214AB) package: molded plastic case with matte tin-plated leads, RoHS-compliant and halogen-free (HE3 suffix), MSL Level 1 rated, and qualified per JESD201 Class 2 whisker test. Cathode is marked by a color band on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes conduction path during transient clamp |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., 24 V rail or sensor output); absorbs positive transients into ground |
Key Features
| Feature | Design Value |

| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without pre-baking or special handling |
Applications
| Automotive Powertrain Control | Industrial Sensor Signal Protection |
|---|---|
Use Scenario: Protecting microcontroller I/O and gate drivers in engine control modules exposed to load dump and inductive kickback from solenoids and fuel injectors. IC Role / Device Role / Timing Role: Transient voltage suppressor placed between 12 V/24 V supply rail and downstream regulator input. Use Value: Clamps 120 V/200 ms load dump transients to ≤41.4 V, preventing regulator latch-up and enabling single-stage protection architecture. |

| Telecom Power Supply Input | Consumer Appliance Motor Drive |
Use Scenario: Safeguarding AC-DC front-end rectifiers and PFC controllers in base station power supplies subjected to lightning-induced surges on AC mains. IC Role / Device Role / Timing Role: Primary-level TVS mounted at AC input stage, upstream of bridge rectifier. Use Value: Absorbs 1500 W surges per IEC 61000-4-5, reducing need for secondary-stage MOVs and lowering overall BOM count. |
Use Scenario: Protecting H-bridge gate drivers in smart washing machine motor inverters from back-EMF during commutation. IC Role / Device Role / Timing Role: TVS placed across each half-bridge leg's high-side and low-side driver supply rails. Use Value: Suppresses >100 V transients within <1 ns, preventing false triggering of overvoltage lockout in gate driver ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30AHE3_A/H | Same VBR, VWM, VC; lower PPPM = 600 W; SMB package (smaller footprint, lower thermal mass) | Not suitable for 1500 W surge events; limited to consumer-grade or low-energy industrial interfaces | Select when board space is constrained and surge threat level is ≤600 W (e.g., USB-C PD port protection) |
| TPSMC33AHE3_A/I | Higher VBR (31.4–34.7 V), VWM = 28.2 V, VC = 45.7 V at 32.8 A; identical package and AEC-Q101 rating | Better suited for 24 V systems with higher margin; may not clamp early enough in 12 V circuits with tight VIN tolerance | Choose for 24 V battery systems where VWM must exceed nominal rail by ≥15% to avoid leakage-related power loss |
Compared with TPSMC30AHE3_A/I, SMBJ30AHE3_A/H offers smaller size but insufficient surge capacity for automotive powertrain use, while TPSMC33AHE3_A/I provides higher standoff for 24 V applications but risks inadequate clamping headroom in 12 V designs-making TPSMC30AHE3_A/I the optimal balance for 12 V/24 V dual-voltage ECUs.

FAQ
What is the maximum clamping voltage of the TPSMC30AHE3_A/I under surge conditions?
The TPSMC30AHE3_A/I has a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current of 36.2 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and reflects worst-case voltage seen by downstream circuitry during transient events. The clamping performance remains stable across -65 °C to +185 °C operating range, making TPSMC30AHE3_A/I suitable for under-hood automotive applications where thermal drift must be minimized.
Is the TPSMC30AHE3_A/I AEC-Q101 qualified?
Yes, the TPSMC30AHE3_A/I is AEC-Q101 qualified. The HE3 suffix explicitly denotes RoHS-compliant, AEC-Q101-qualified construction per Vishay's ordering nomenclature. Qualification includes stress testing for high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and electrostatic discharge (HBM/MM/CDM), confirming suitability for automotive powertrain and chassis applications. Documentation is available in Vishay's qualification report Q-2023-TPSMC-HE3.
What does the "A/I" suffix mean in TPSMC30AHE3_A/I?
The "A/I" suffix in TPSMC30AHE3_A/I indicates two distinct ordering attributes: "A" is the revision code denoting the specific device variant per Vishay's internal documentation (Document Number 88407, Revision 19-Jan-2024), and "I" specifies the packaging format-13-inch diameter plastic tape and reel with 3500 units per reel. This differs from "H"-suffixed variants, which use 7-inch reels with 850 units. Both formats share identical electrical and mechanical specifications.
Can TPSMC30AHE3_A/I replace TPSMC30AHM3_A/I in a design?
Yes, TPSMC30AHE3_A/I can replace TPSMC30AHM3_A/I in most applications, as both share identical electrical parameters, SMC package dimensions, AEC-Q101 qualification, and RoHS compliance. The sole difference is material composition: HM3 denotes halogen-free molding compound, while HE3 is standard RoHS-compliant (not necessarily halogen-free). If halogen-free content is not mandated by end-customer specification, TPSMC30AHE3_A/I is a functionally equivalent drop-in replacement with no PCB or layout changes required.
What is the reverse leakage current of TPSMC30AHE3_A/I at maximum operating temperature?
At TJ = 150 °C and VWM = 25.6 V, the TPSMC30AHE3_A/I exhibits a maximum reverse leakage current (ID) of 10 µA. This value is specified in the Electrical Characteristics table (page 2 of Document 88407) and is critical for low-power always-on circuits where standby current budget is constrained. At room temperature (25 °C), leakage is ≤1.0 µA, ensuring minimal impact on battery-powered sensor nodes using TPSMC30AHE3_A/I for signal-line protection.
