Product details
Overview
VTVS36ASMF-M3-08 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for ESD and surge protection of low-voltage DC lines. It features a 36.0 V stand-off voltage (VRWM), 40.9–45.2 V reverse breakdown voltage (VBR at IT = 1 mA), 61 A peak pulse current (IPPM, 10/1000 μs), 61 V maximum clamping voltage (VC), and 342 pF typical junction capacitance at 0 V.
For engineers reviewing the VTVS36ASMF-M3-08 datasheet, VTVS36ASMF-M3-08 pinout, VTVS36ASMF-M3-08 application, or VTVS36ASMF-M3-08 equivalent, this device serves as a compact, AEC-Q101-qualified TVS for automotive infotainment power rails, USB 2.0 data lines, and industrial sensor interfaces requiring ±30 kV IEC 61000-4-2 ESD immunity and fast clamping response.
Technical Context
This unidirectional TVS diode operates with a 36.0 V maximum working voltage and clamps transients up to 61 V at 61 A (10/1000 μs), delivering 400 W peak pulse power. Its low 342 pF capacitance enables use on high-speed signal lines without signal integrity degradation.
Constructed in the halogen-free SMF (DO-219AB) package, it supports wave and reflow soldering with MSL level 1 rating and 260 °C peak temperature tolerance. Junction temperature range spans −55 °C to +175 °C, supporting under-hood automotive deployment.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/57T | Same VRWM (36 V), but higher VC = 58.1 V at 64.5 A; SMA package (DO-214AC), larger footprint (4.5 × 2.7 mm). | Higher power rating (400 W) but less suitable for space-constrained USB or sensor modules due to 2.5× larger area. | Select when board layout allows larger footprint and lower clamping voltage is prioritized over size. |
| 1.5SMC36A | Same VRWM (36 V), VC = 58.1 V at 64.5 A; SMC package (DO-214AB), 7.1 × 6.2 mm, 3× height of SMF. | Designed for high-energy industrial mains protection; incompatible with fine-pitch automotive PCBs. | Choose only for non-portable equipment where thermal mass and surge margin outweigh miniaturization needs. |
Compared with SMAJ36A-E3/57T and 1.5SMC36A, VTVS36ASMF-M3-08 delivers identical 36 V standoff and 400 W rating in a 3.9 × 1.9 mm footprint-enabling placement directly at USB connectors or sensor headers where space and parasitic inductance must be minimized.

FAQ
What is the clamping voltage of the VTVS36ASMF-M3-08 at its rated peak pulse current?
The VTVS36ASMF-M3-08 has a maximum reverse clamping voltage (VC) of 61 V at 61 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized surge conditions and defines the upper voltage limit imposed on the protected circuit during transient events, ensuring downstream ICs remain within safe operating limits.
Is the VTVS36ASMF-M3-08 qualified for automotive applications?
Yes, the VTVS36ASMF-M3-08 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life, temperature cycling, and mechanical shock. Its −55 °C to +175 °C operating junction temperature range and halogen-free SMF package make it suitable for under-hood and infotainment applications where reliability under thermal and vibration stress is critical.
What is the junction capacitance of the VTVS36ASMF-M3-08, and why does it matter for signal lines?
The VTVS36ASMF-M3-08 exhibits 342 pF typical junction capacitance at 0 V and 1 MHz. This low value minimizes loading on high-speed signal paths-such as USB 2.0 differential pairs-preventing signal distortion, timing skew, or failure to meet eye diagram specifications during compliance testing.
Can the VTVS36ASMF-M3-08 replace older SMAJ36A devices in existing designs?
The VTVS36ASMF-M3-08 is not a pin-compatible replacement for SMAJ36A due to differing packages: SMF (DO-219AB) vs. SMA (DO-214AC). While both share 36 V VRWM and 400 W rating, the VTVS36ASMF-M3-08 requires updated land pattern and stencil design. Its smaller footprint and lower profile may necessitate layout revision but enable denser routing near connectors.
Does the VTVS36ASMF-M3-08 support lead-free reflow soldering?
Yes, the VTVS36ASMF-M3-08 is fully compatible with lead-free reflow soldering processes, with a peak temperature rating of 260 °C per J-STD-020. Its MSL level 1 classification means it can be stored indefinitely at ambient conditions without baking, simplifying manufacturing logistics for high-volume SMT lines.
