Product details
Overview
T4F13AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in the eSMP® Series, designed for automotive-grade overvoltage protection. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 μs), 18.2 V maximum clamping voltage at 22.0 A surge current, and operates up to +185 °C junction temperature - deployed on signal lines of automotive sensor units to protect MOSFETs and ICs from inductive switching transients.
For engineers reviewing the T4F13AHM3/I datasheet, T4F13AHM3/I pinout, T4F13AHM3/I application, or T4F13AHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, SMF (DO-219AB) package compatibility, unidirectional polarity with cathode band marking, and thermal performance validated under high-reliability automotive conditions.
Technical Context
The T4F13AHM3/I employs passivated anisotropic rectifier technology optimized for high-temperature stability and low leakage. Its junction passivation enables reliable operation at TJ = 185 °C and meets MSL Level 1 per J-STD-020 with 260 °C peak reflow tolerance.
It delivers precise clamping behavior with 0.072 %/°C temperature coefficient of VBR, 1.0 μA max reverse leakage at VWM (TJ = 150 °C), and 135–160 °C/W junction-to-ambient thermal resistance on FR4 PCB - supporting robust transient suppression in space-constrained automotive ECUs and ADAS sensor interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5A (Vishay) | Same VBR (13.0 V) but SMA package (DO-214AC); higher RthJA (190 °C/W); lower PPPM (400 W same, but lower IPPM derating above 75 °C) | Less suitable for under-hood use due to lower thermal capability; requires larger PCB area | Select when legacy SMA footprint exists and ambient temperature stays below 105 °C |
| 1.5SMC13A (ON Semiconductor) | Same VBR range but SMC (DO-214AB) package; 150 °C TJ max; not AEC-Q101 qualified; higher VC (21.5 V) | Not approved for automotive production; limited to industrial/commercial designs | Acceptable only for non-automotive cost-sensitive applications where AEC-Q101 is not mandated |
Compared with SMAJ13A-E3/5A and 1.5SMC13A, the T4F13AHM3/I provides superior thermal margin (185 °C vs. 150–175 °C), smaller footprint (SMF vs. SMA/SMC), and full AEC-Q101 validation - making it the preferred choice for new automotive designs requiring long-term reliability in high-temperature zones.

FAQ
What is the maximum clamping voltage of the T4F13AHM3/I at its rated surge current?
The T4F13AHM3/I has a maximum clamping voltage (VC) of 18.2 V when subjected to its peak pulse current (IPPM) of 22.0 A under a 10/1000 μs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 87645) and ensures protected circuits remain within safe operating limits during transient events. The T4F13AHM3/I maintains this clamping performance across its full operating temperature range.
Is the T4F13AHM3/I qualified for automotive applications?
Yes, the T4F13AHM3/I is AEC-Q101 qualified, having passed all required stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling (TCT), and mechanical shock. Its 185 °C maximum junction temperature and MSL Level 1 rating further validate its suitability for under-hood and safety-critical automotive systems. The T4F13AHM3/I is explicitly designated for automotive sensor and ECU protection in Vishay's official documentation.
What package does the T4F13AHM3/I use, and what are its key mechanical attributes?
The T4F13AHM3/I uses the SMF (DO-219AB) package: a low-profile surface-mount outline measuring 2.9 mm × 1.3 mm × 1.08 mm with matte tin-plated terminals. It features a cathode identification band, complies with UL 94 V-0 flammability, and meets JESD201 Class 2 whisker resistance. The T4F13AHM3/I's footprint is optimized for automated placement and reflow soldering, including lead-free processes up to 260 °C peak temperature.
How does the T4F13AHM3/I compare to the T4F13A without the HM3/I suffix?
The "HM3/I" suffix on T4F13AHM3/I denotes halogen-free, RoHS-compliant construction (HM3) and packaging in 13-inch tape-and-reel (I). Electrically and thermally, the T4F13AHM3/I is identical to the base T4F13A - same VBR, VWM, VC, PPPM, and AEC-Q101 qualification. The T4F13AHM3/I is the production-standard variant specified for automotive supply chains requiring environmental compliance and high-volume SMT handling.
What is the reverse leakage current specification for the T4F13AHM3/I at elevated temperature?
At VWM = 11.1 V and TJ = 150 °C, the T4F13AHM3/I exhibits a maximum reverse leakage current (ID) of 1.0 μA. This low leakage ensures minimal power loss and signal distortion in always-on automotive subsystems such as body controllers and sensor interfaces. The T4F13AHM3/I maintains this specification across its full -65 °C to +185 °C operating junction temperature range, as verified in Vishay's characterization data.
