Product details
Overview
VTVS36ASMF-HM3-08 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for ESD and surge protection on low-voltage DC lines such as USB, HDMI, and automotive sensor interfaces. It features 36.0 V stand-off voltage (VRWM), 40.9–45.2 V reverse breakdown voltage (VBR), and clamps to 61 V at 6.24 A peak pulse current (10/1000 μs), with ±30 kV IEC 61000-4-2 contact/air discharge rating.
For engineers reviewing the VTVS36ASMF-HM3-08 datasheet, VTVS36ASMF-HM3-08 pinout, VTVS36ASMF-HM3-08 application, or VTVS36ASMF-HM3-08 equivalent, key selection criteria include its 342 pF capacitance at 0 V, 175 °C max junction temperature, halogen-free construction, AEC-Q101 qualification option, and compatibility with SOD-123W footprint for space-constrained PCB layouts.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 40.9–45.2 V breakdown threshold at 1 mA test current. Its low-clamping behavior (VC = 61 V @ IPPM = 6.24 A) limits voltage overshoot during transients while maintaining low leakage (<0.05 μA at VRWM = 36.0 V).
The SMF package enables wave and reflow soldering, with MSL level 1 moisture sensitivity and peak reflow tolerance up to 260 °C. Its "Low-Noise" technology ensures sub-nanosecond response time, critical for protecting high-speed digital interfaces against fast-rising ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform; sustains surge energy without failure) |
| Stand-off Voltage (VRWM) | 36.0 V (maximum continuous reverse voltage before significant leakage) |

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 SMA package (DO-214AC); 400 W rating; ±5 % VBR; 64 V VC @ 6.1 A | Larger footprint (4.5 × 2.7 mm vs. 3.9 × 1.9 mm); higher thermal resistance (RthJL = 35 K/W vs. 20 K/W) | Choose SMAJ36A-E3/57T only if board space allows larger package and thermal design accommodates lower power density. |
| 1.5SMC36A | Same VRWM (36 V), SMC package (DO-214AB); 1500 W rating; ±5 % VBR; 58.1 V VC @ 25.8 A | Higher power handling but 7.1 × 6.2 mm size; not suitable for space-constrained USB/HDMI layouts | Prefer 1.5SMC36A only for high-energy surge zones like power input stages-not signal-line protection. |
Compared with SMAJ36A-E3/57T and 1.5SMC36A, VTVS36ASMF-HM3-08 delivers identical 36 V standoff and 400 W capability in the smallest possible footprint (SMF), with superior thermal performance (20 K/W) and optimized capacitance (342 pF) for high-speed data lines-making it the preferred choice for compact, thermally demanding, or high-frequency interface protection.

FAQ
What is the maximum clamping voltage of the VTVS36ASMF-HM3-08 under peak pulse conditions?
The VTVS36ASMF-HM3-08 clamps to a maximum of 61 V when subjected to its rated peak pulse current of 6.24 A (10/1000 μs waveform). This value is measured at the device terminals and defines the upper voltage limit imposed on the protected circuit during transient events, ensuring downstream ICs rated for 3.3 V or 5 V logic remain within safe operating margins.
Is the VTVS36ASMF-HM3-08 RoHS-compliant and halogen-free?
Yes, the VTVS36ASMF-HM3-08 is both RoHS-compliant and halogen-free, meeting Vishay's material categorization standard per document 99912. The molding compound is UL 94 V-0 rated, and terminations are lead (Pb)-free with matte tin plating-fully aligned with EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 2 requirements.
Does the VTVS36ASMF-HM3-08 have AEC-Q101 qualification?
The VTVS36ASMF-HM3-08 is offered in an AEC-Q101 qualified version (denoted by "H" in the ordering code), confirming validation for automotive applications including temperature cycling, humidity testing, and mechanical shock per AEC-Q101-001. Standard versions without "H" are not AEC-Q101 certified.
What is the capacitance of the VTVS36ASMF-HM3-08 and how does it affect high-speed signal lines?
The VTVS36ASMF-HM3-08 exhibits 342 pF typical capacitance at 0 V bias and 1 MHz. This value is appropriate for USB 2.0 (480 Mbps) and HDMI 1.4 (TMDS) interfaces where signal integrity tolerates moderate loading, but is too high for USB 3.0 Gen 1 (5 Gbps) or PCIe Gen 3, which require <1–2 pF devices. Layout best practices-short traces, symmetric placement-help mitigate insertion loss.
Can the VTVS36ASMF-HM3-08 be used in bidirectional protection configurations?
No, the VTVS36ASMF-HM3-08 is a unidirectional TVS diode, intended for DC-biased lines where polarity is fixed (e.g., 36 V supply rail to ground). For bidirectional AC or differential signal protection (e.g., RS-485, CAN), a dedicated bidirectional variant such as VTVS36BSMF-HM3-08-or two unidirectional devices in series opposition-must be used instead.
