Product details
Overview
TPSMC7.5HE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for clamping voltage transients on power and signal lines. It features 7.5 V nominal breakdown voltage (VBR = 6.75–8.25 V), 6.05 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 128 A peak pulse current (IPPM), and 11.7 V maximum clamping voltage (VC) - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the TPSMC7.5HE3_A/H datasheet, TPSMC7.5HE3_A/H pinout, TPSMC7.5HE3_A/H application, or TPSMC7.5HE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, low clamping ratio (VC/VWM ≈ 1.93), and MSL Level 1 reflow compatibility - all critical for high-reliability board-level ESD and surge protection design.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable performance under thermal stress. Its unidirectional architecture provides low forward voltage drop (VF = 3.5 V at 100 A) and fast response time to transient events, enabling effective suppression of inductive switching spikes and lightning-induced surges.
Rated for operation from −65 °C to +185 °C, it meets AEC-Q101 stress test requirements and supports high-temperature automotive environments. The device is characterized using standardized 10/1000 µs waveform testing per ANSI/IEEE C62.35 and derated above 25 °C ambient per published thermal curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 6.75–8.25 V at 10 mA - defines minimum voltage at which clamping initiates; ensures reliable turn-on before downstream circuit damage. |
| Stand-off Voltage VWM | 6.05 V - maximum continuous reverse working voltage; must exceed normal operating rail voltage (e.g., 5 V or 6 V systems). |
| Peak Pulse Power PPPM | 1500 W (10/1000 µs) - determines energy-handling capability against transient surges like ISO 7637-2 pulse 5a. |
| Clamping Voltage VC | 11.7 V at 128 A - maximum voltage seen by protected circuit during worst-case surge; critical for I/O voltage margining. |
| Junction Temperature Range | −65 °C to +185 °C - enables use in under-hood automotive, industrial motor drives, and high-ambient environments without derating. |
| AEC-Q101 Qualification | Qualified - confirms reliability for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
| MSL Level | Level 1 (J-STD-020) - supports standard 260 °C lead-free reflow without moisture sensitivity concerns. |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, matte tin-plated leads, cathode indicated by color band. Meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected line. | Provides low forward voltage path during fault conditions; ties to ground or return path in unidirectional configuration. |
| Cathode | Current exit terminal in forward bias; marked by color band; connected to higher-potential side (e.g., VIN, signal line). | Defines polarity-sensitive clamping direction; must be placed between protected node and power/signal source. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Enables robust protection against high-energy transients such as load dump (ISO 16750-2) and inductive kickback in 12 V automotive systems. |
| 185 °C maximum junction temperature | Supports extended operation in engine control units, battery management systems, and industrial inverters without thermal shutdown. |
| AEC-Q101 qualification | Validates long-term reliability under automotive stress conditions including temperature cycling, humidity, and high-temperature life testing. |
| Low clamping ratio (VC/VWM = 1.93) | Minimizes overvoltage exposure to downstream components while maintaining sufficient margin above normal operating voltage. |
| MSL Level 1 reflow compatibility | Eliminates pre-bake requirement and supports standard SMT assembly processes with peak reflow up to 260 °C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5AHE3_A/H | DO-214AC (SMA) package; lower PPPM (400 W); tighter VBR tolerance (±5 %); same VWM and VC. | Lower power handling limits use to sub-100 A surge scenarios; suitable for space-constrained consumer PCBs where 1500 W is not required. | Select when footprint area is constrained and surge threat level is moderate (e.g., USB power inputs, low-power sensors). |
| TPSMC7.5AHE3_A/H | Same DO-214AB package; ±5 % VBR tolerance (7.13–7.88 V); slightly higher VWM (6.4 V); identical PPPM and VC (11.3 V). | Tighter breakdown tolerance improves predictability in precision clamping designs; preferred for automotive systems requiring tighter parametric control. | Select when tighter VBR distribution is needed for consistent clamping threshold across production lots. |
Compared with SMAJ7.5AHE3_A/H, TPSMC7.5HE3_A/H delivers 3.75× higher surge power handling in the same mounting footprint class, while TPSMC7.5AHE3_A/H offers improved VBR consistency at no cost to clamping performance - making the base TPSMC7.5HE3_A/H optimal for cost-sensitive, high-energy protection where ±10 % tolerance is acceptable.

FAQ
What is the breakdown voltage range for TPSMC7.5HE3_A/H?
The TPSMC7.5HE3_A/H has a guaranteed breakdown voltage (VBR) range of 6.75 V to 8.25 V at 10 mA test current, per Vishay Document Number 88407. This ±10 % tolerance reflects the standard specification for the base "TPSMC7.5" variant, distinguishing it from the tighter ±5 % "TPSMC7.5A" version. The full range ensures reliable clamping initiation across manufacturing lots and temperature extremes.
Is TPSMC7.5HE3_A/H qualified for automotive applications?
Yes, TPSMC7.5HE3_A/H is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, confirming its suitability for under-hood and powertrain electronics. It passes stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling - all documented in Vishay's qualification reports referenced in datasheet revision 22-Jul-16.
What does the "HE3_A/H" suffix mean in TPSMC7.5HE3_A/H?
The "HE3" denotes RoHS-compliant, matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 2 whisker resistance. "A/H" specifies the packaging: "A" is the revision code, and "H" indicates 7-inch tape-and-reel delivery with 850 units per reel, per Vishay's ordering information table in Document Number 88407.
What is the maximum clamping voltage of TPSMC7.5HE3_A/H at rated surge current?
The TPSMC7.5HE3_A/H exhibits a maximum clamping voltage (VC) of 11.7 V at its rated peak pulse current (IPPM) of 128 A, measured under the standard 10/1000 µs waveform. This value is confirmed in the Electrical Characteristics table on page 2 of the datasheet and represents the worst-case voltage imposed on protected circuitry during a full-rated transient event.
Can TPSMC7.5HE3_A/H replace TPSMC7.5AHE3_A/H in existing designs?
TPSMC7.5HE3_A/H can serve as a functional alternative to TPSMC7.5AHE3_A/H in most applications, but with a wider VBR tolerance (±10 % vs. ±5 %) and slightly lower VWM (6.05 V vs. 6.4 V). Designers should verify that the broader breakdown range does not compromise clamping margin in safety-critical circuits - especially where precise overvoltage thresholds are enforced.
