Product details
Overview
TPSMC7.5AHE3_B/I 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 7.5 V nominal breakdown voltage (VBR), 6.4 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 μs), 11.3 V maximum clamping voltage at 133 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPSMC7.5AHE3_B/I datasheet, TPSMC7.5AHE3_B/I pinout, TPSMC7.5AHE3_B/I application, or TPSMC7.5AHE3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 10 mA test current for VBR, and low 0.052 %/°C temperature coefficient of breakdown voltage.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under high-temperature conditions (TJ = 185 °C). Its unidirectional configuration enables protection of DC-biased lines without reverse conduction during normal operation.
The device meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 requirements, with matte tin-plated leads and UL 94 V-0 molding compound - confirming suitability for automotive and industrial reflow assembly environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 7.13 / 7.50 / 7.88 V at 10 mA - defines precise voltage threshold where clamping begins under surge conditions |
| VWM | 6.40 V - maximum continuous reverse voltage before leakage exceeds 500 μA, ensuring no false triggering in normal operation |
| VC @ IPPM | 11.3 V at 133 A - clamped voltage seen by protected circuit during full 1500 W transient, limiting stress on downstream components |
| PPPM | 1500 W (10/1000 μs waveform) - peak surge energy handling capacity for inductive switching and lightning-induced transients |
| TJ max. | +185 °C - enables reliable operation in under-hood automotive or high-power industrial environments without derating |
| αT | 0.052 %/°C - low temperature coefficient ensures stable VBR across wide thermal ranges, critical for precision protection |
| IR @ VWM | 500 μA at 25 °C - low leakage preserves system efficiency and avoids false fault detection in high-impedance circuits |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, cathode indicated by color band. Dimensions: 6.22 mm × 5.59 mm × 2.46 mm (L × W × H), with 8.0 mm × 8.0 mm copper pad requirement per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction or surge clamping | Connected to protected line's lower-potential side (e.g., ground-referenced signal or return path) |
| Cathode | Current exit point during clamping; marked by band | Connected to higher-potential side (e.g., VCC, bus, or signal line); determines unidirectional clamping direction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per AEC standard |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow without moisture-related delamination or popcorn failure |
| 1500 W peak pulse power (10/1000 μs) | Handles high-energy transients from relay coil decay, motor commutation, or ESD-coupled surges in compact SMC footprint |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin for sensitive ICs |
| Junction temperature rating: -65 to +185 °C | Supports extended operation in engine control units, power inverters, and industrial PLCs without thermal derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Same VBR (7.5 V), but lower PPPM = 400 W; SMA package (smaller, lower thermal mass) | Limited to lower-energy transients; not AEC-Q101 qualified; unsuitable for automotive under-hood use | Select when space-constrained and surge energy ≤400 W; verify thermal design with smaller pad area |
| TPSMC7.5AHM3_B/I | Identical electrical specs; halogen-free version with same RoHS and AEC-Q101 compliance | No functional difference; required only where halogen-free material declaration is mandated (e.g., EU automotive Tier 1) | Choose HM3 for halogen-free compliance; HE3 remains optimal for general AEC-Q101 applications |
Compared with SMAJ7.5A, TPSMC7.5AHE3_B/I delivers 3.75× higher surge power handling and automotive qualification; versus TPSMC7.5AHM3_B/I, it offers identical protection performance with standard RoHS compliance - making HE3 the default choice unless halogen-free materials are contractually required.

FAQ
What is the clamping voltage of TPSMC7.5AHE3_B/I at its rated peak pulse current?
The TPSMC7.5AHE3_B/I has a maximum clamping voltage (VC) of 11.3 V when subjected to its peak pulse current (IPPM) of 133 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 and Table on page 2 of the official Vishay datasheet (Document Number: 88407, Revision: 19-Jan-2024), and defines the upper voltage limit imposed on protected circuits during worst-case surge events. The TPSMC7.5AHE3_B/I maintains this clamping performance across its full operating temperature range.
Is TPSMC7.5AHE3_B/I qualified for automotive applications?
Yes, TPSMC7.5AHE3_B/I is AEC-Q101 qualified, as confirmed by the HE3 suffix in its part number and explicitly stated in the "FEATURES" section of the Vishay datasheet. It undergoes stress testing for temperature cycling, high-temperature reverse bias, and mechanical shock per AEC-Q101 Rev D. The TPSMC7.5AHE3_B/I is rated for junction temperatures up to +185 °C, supporting under-hood and transmission-control module deployments where thermal robustness is essential.
What does the "B/I" suffix mean in TPSMC7.5AHE3_B/I?
The "B/I" suffix in TPSMC7.5AHE3_B/I indicates two distinct ordering attributes: "B" denotes the revision code (revision B of the base device), and "I" specifies the packaging format - 13-inch diameter plastic tape and reel, with a base quantity of 3500 units per reel. This matches the "PREFERRED PACKAGE CODE" and "DELIVERY MODE" entries in the Ordering Information table on page 3 of the Vishay datasheet (88407).
How does TPSMC7.5AHE3_B/I differ from TPSMC7.5AHM3_B/I?
TPSMC7.5AHE3_B/I and TPSMC7.5AHM3_B/I share identical electrical specifications, package (SMC), AEC-Q101 qualification, and RoHS compliance. The sole difference is material composition: HM3 denotes halogen-free molding compound, while HE3 uses standard RoHS-compliant compound. Both meet JESD201 Class 2 whisker resistance and MSL Level 1. The TPSMC7.5AHE3_B/I is appropriate for most automotive and industrial designs unless halogen-free content is contractually mandated.
What is the maximum leakage current of TPSMC7.5AHE3_B/I at its stand-off voltage?
The maximum reverse leakage current (IR) of TPSMC7.5AHE3_B/I is 500 μA at its stand-off voltage (VWM) of 6.40 V and ambient temperature of 25 °C, as specified in the Electrical Characteristics table on page 2 of the Vishay datasheet. At elevated temperature (TJ = 150 °C), leakage increases to 5000 μA - a design consideration for high-temperature bias networks. This low leakage ensures minimal power loss and avoids false triggering in high-impedance protection configurations.
