Product details
Overview
TPSMC11AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping fast voltage transients on power and signal lines. It features 11.0 V nominal breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 15.6 V maximum clamping voltage at 96.2 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - deployed in automotive power rail protection and industrial sensor interface circuits.
For engineers reviewing the TPSMC11AHE3_A/I datasheet, TPSMC11AHE3_A/I pinout, TPSMC11AHE3_A/I application, or TPSMC11AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 1500 W surge rating, low clamping ratio (VC/VWM ≈ 1.66), and compatibility with high-reliability PCB layouts requiring MSL Level 1 reflow.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable breakdown characteristics across temperature. Its 185 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments and industrial control systems where thermal derating and long-term reliability are critical.
The device delivers 1500 W peak pulse power per 10/1000 µs waveform with low incremental surge resistance and sub-nanosecond response time. Clamping performance is validated at 96.2 A IPPM, yielding VC = 15.6 V - enabling robust protection of 12 V nominal systems against ISO 7637-2 and IEC 61000-4-5 surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 10.5 / 11.0 / 11.6 V - ensures reliable triggering above 9.40 V system operating voltage while avoiding false trips |
| VWM | 9.40 V - maximum continuous reverse voltage before leakage exceeds 5.0 µA, compatible with 12 V nominal rails |
| VC @ IPPM | 15.6 V - clamps 96.2 A transient to safe level for downstream 16 V-rated ICs and MOSFETs |
| PPPM | 1500 W - sustains single 10/1000 µs surges per JEDEC standards without degradation |
| TJ max. | +185 °C - supports operation in engine control units and power converters with minimal thermal derating |
| Polarity | Unidirectional - protects positive-rail circuits only; requires separate device for negative transients |
| MSL Level | Level 1 (260 °C peak) - enables standard lead-free reflow without moisture sensitivity concerns |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-E3/5A (Vishay) | Same VBR range but lower PPPM = 400 W; SMA package (smaller footprint, lower thermal mass) | Limited to low-energy transients; unsuitable for automotive load dump or telecom surge testing | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 ESD only |
| 1.5KE11A (ON Semiconductor) | Through-hole DO-201 package; identical VBR, VC, and PPPM; higher IFSM = 225 A | Requires wave solder or hand-solder; incompatible with fully automated SMT lines | Choose for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMAJ11A-E3/5A and 1.5KE11A, the TPSMC11AHE3_A/I provides the optimal balance of high surge capability (1500 W), SMT manufacturability (SMC package), and automotive-grade reliability (AEC-Q101, TJ = 185 °C), making it the preferred choice for volume production of automotive and industrial electronics.

FAQ
What is the exact breakdown voltage tolerance for TPSMC11AHE3_A/I?
The TPSMC11AHE3_A/I has a guaranteed breakdown voltage range of 10.5 V (minimum) to 11.6 V (maximum) at 1 mA test current, with 11.0 V as the nominal value. This ±5 % tolerance is verified per ANSI/IEEE C62.35 and maintained across the full -65 °C to +185 °C operating junction temperature range using the published temperature coefficient of 0.067 %/°C.
Is TPSMC11AHE3_A/I qualified to AEC-Q101, and what does that cover?
Yes, TPSMC11AHE3_A/I is AEC-Q101 qualified - confirmed by Vishay's documentation for base P/NHE3 ordering codes. This qualification covers stress tests including HTGB, HTRB, TCT, UHAST, and mechanical shock, validating reliability for automotive electronic control units. The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified construction.
What is the maximum clamping voltage of TPSMC11AHE3_A/I under surge conditions?
The TPSMC11AHE3_A/I clamps to a maximum of 15.6 V when subjected to its rated peak pulse current of 96.2 A (10/1000 µs waveform). This value is measured per JEDEC standards and represents the worst-case voltage seen by downstream circuitry during a full-energy transient event.
Can TPSMC11AHE3_A/I be used in bidirectional protection schemes?
No, TPSMC11AHE3_A/I is unidirectional only, as stated in the Vishay datasheet. It conducts in reverse bias to clamp positive transients on a positive rail but offers no protection against negative-going surges. For bidirectional protection, a dedicated bidirectional TVS such as TPSMC11CAHE3_A/I must be selected instead.
What is the thermal resistance junction-to-ambient (RθJA) for TPSMC11AHE3_A/I in standard PCB layout?
Vishay specifies RθJA = 50 °C/W for the TPSMC11AHE3_A/I when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads at each terminal. This value assumes FR-4 board material and natural convection; actual thermal performance improves with internal copper planes or forced airflow.
