Product details
Overview
TPSMC8.2AHE3/9AT 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 8.2 V nominal breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 μs), 124 V maximum clamping voltage at 124 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPSMC8.2AHE3/9AT datasheet, TPSMC8.2AHE3/9AT pinout, TPSMC8.2AHE3/9AT application, or TPSMC8.2AHE3/9AT equivalent, this device supports high-reliability automotive and industrial surge protection where AEC-Q101 qualification, low leakage (<200 μA at VWM), and stable clamping under thermal stress are critical selection criteria.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver fast response time and low incremental surge resistance. Its unidirectional polarity and 10 mA test current ensure precise VBR specification with ±5% tolerance (7.79–8.61 V), while the 0.056 %/°C temperature coefficient enables predictable voltage drift across operating range.
The device is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine) and maintains clamping performance on standard 8.0 mm × 8.0 mm copper pads. Its MSL Level 1 rating and matte tin-plated leads meet J-STD-002 solderability and JESD 22-B102 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 7.79 / 8.20 / 8.61 V - Ensures reliable turn-on above system operating voltage while avoiding false triggering |
| VWM | 7.02 V - Maximum continuous reverse voltage before leakage exceeds 200 μA, compatible with 5 V–6 V rail systems |
| PPPM | 1500 W (10/1000 μs) - Handles high-energy transients from inductive switching or ESD without failure |
| VC @ IPPM | 124 V - Clamped voltage during 124 A surge, limiting downstream IC stress to safe levels |
| TJ max. | +185 °C - Enables operation in under-hood automotive or high-temperature industrial environments |
| IR @ VWM | 200 μA - Low leakage preserves battery life and signal integrity in always-on circuits |
| AEC-Q101 qualified | Yes - Validated for automotive electronics per stress-test requirements including HTGB, HTRB, and TC |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, cathode indicated by molded band. Dimensions: 7.11 mm × 6.22 mm × 2.90 mm (L × W × H). RoHS-compliant, halogen-free option available (HM3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to protected line ground or low-side return path | Completes conduction path during transient clamp; must be routed with low-inductance trace to minimize overshoot |
| Cathode | Current exit terminal in forward bias; marked by color band, connected to protected line input or supply rail | Defines polarity orientation-reversal prevents clamping; critical for correct placement on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation optimized design | Reduces surface leakage and improves long-term reliability under humidity and thermal cycling |
| 1500 W peak pulse power (10/1000 μs) | Withstands repeated load-dump or ISO 7637-2 Pulse 5a surges without degradation |
| Low incremental surge resistance | Minimizes VC rise during fast-rising transients (e.g., ESD > 30 kV), improving protection margin |
| MSL Level 1, 260 °C reflow compatible | Enables single-pass lead-free assembly without preconditioning or special handling |
| TJ = 185 °C capability | Supports placement near heat sources (e.g., power MOSFETs, DC/DC converters) without derating |
Applications
| Automotive Power Line Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 16750-2) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 15 V. Use Value: Withstands 1500 W pulses and maintains <124 V clamping, preventing damage to MCU power inputs and CAN transceivers. |
Use Scenario: Shielding analog outputs of pressure/temperature sensors from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS on sensor output line to ground, preserving signal bandwidth up to 1 MHz. Use Value: 200 μA leakage at 7.02 V avoids DC offset errors; fast response limits transient duration to <1 ns. |
| Consumer Power Adapter Input Stage | Telecom DC Power Feed Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters after rectification and bulk capacitance. IC Role / Device Role / Timing Role: Standoff-rated TVS across +VOUT and GND to absorb flyback spikes from transformer leakage inductance. Use Value: 8.2 V VBR aligns with 9 V nominal output; 124 V VC ensures downstream LDOs remain within absolute maximum ratings. |
Use Scenario: Protecting PoE-powered equipment (IEEE 802.3af/at) from induced surges on 48 V DC feed lines. IC Role / Device Role / Timing Role: Primary-stage TVS on DC input before DC/DC converter, referenced to common-mode ground. Use Value: AEC-Q101 qualification and 185 °C rating support outdoor telecom enclosures with wide ambient swings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | Lower PPPM (600 W), smaller SMB package (DO-214AA), VBR = 8.0–8.89 V | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when space-constrained layout permits smaller footprint and automotive qualification is unnecessary |
| TPSMC8.2AHE3/TR13 | Identical electrical specs; differs only in packaging-13" tape-and-reel (3500 pcs) vs. 7" reel (850 pcs) of TPSMC8.2AHE3/9AT | No functional or application difference; same thermal, electrical, and mechanical behavior | Choose based on production volume and SMT line feeder compatibility-not for performance differentiation |
Compared with SMBJ8.0A and TPSMC8.2AHE3/TR13, the TPSMC8.2AHE3/9AT delivers higher surge robustness (1500 W vs. 600 W) and automotive qualification, while its 7" reel format supports mid-volume prototyping and pilot runs without overstocking.

FAQ
What is the breakdown voltage tolerance for TPSMC8.2AHE3/9AT?
The TPSMC8.2AHE3/9AT has a specified breakdown voltage range of 7.79 V (min) to 8.61 V (max) at 10 mA test current, representing ±5% around the nominal 8.2 V value. This tight tolerance ensures consistent clamping behavior across production lots and supports precise system-level overvoltage margining without additional derating.
Is TPSMC8.2AHE3/9AT suitable for bidirectional transient protection?
No, TPSMC8.2AHE3/9AT is unidirectional only, as confirmed in the Vishay datasheet. It conducts only during reverse-bias overvoltage events and does not protect against positive-going transients on grounded lines. For bidirectional protection, a separate device such as the SMBJ8.0CA or TPSMC8.0CA must be selected.
Does TPSMC8.2AHE3/9AT require derating at elevated ambient temperatures?
Yes - the peak pulse power rating of TPSMC8.2AHE3/9AT must be derated above 25 °C ambient, per Figure 2 in the datasheet. At 125 °C ambient, the 1500 W rating drops to approximately 750 W. Designers must verify clamping voltage and energy absorption under worst-case thermal conditions using the published derating curve.
What is the meaning of the "HE3" and "/9AT" suffixes in TPSMC8.2AHE3/9AT?
The "HE3" suffix indicates RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads. The "/9AT" denotes Vishay's internal tape-and-reel packaging code for 7" diameter reels containing 850 units, conforming to EIA-481 standards. Both suffixes are essential for correct procurement and compliance verification.
Can TPSMC8.2AHE3/9AT be used in place of SMAJ8.2A?
TPSMC8.2AHE3/9AT is not a direct replacement for SMAJ8.2A due to package differences: SMAJ uses DO-214AC (SMA), while TPSMC uses larger DO-214AB (SMC). Though electrically similar, the SMC package offers higher surge capability (1500 W vs. 400 W) and thermal mass but requires revised PCB land pattern and stencil design.
