Product details
Overview
SMF5V0A-HM3_A08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in the SMF (DO-219AB) package, designed for low-capacitance transient suppression on high-speed data lines. It features a 5.0 V stand-off voltage, 9.2 V maximum clamping voltage at 21.7 A peak pulse current, ±30 kV IEC 61000-4-2 ESD immunity, and 1120 pF typical capacitance at 0 V - optimized for USB 2.0, HDMI, and industrial sensor interface protection.
For engineers reviewing the SMF5V0A-HM3_A08 datasheet, SMF5V0A-HM3_A08 pinout, SMF5V0A-HM3_A08 application, or SMF5V0A-HM3_A08 equivalent, key selection criteria include clamping voltage under 50 A surge, sub-2 ns response time, AEC-Q101 qualification status, SOD-123W-compatible footprint, and thermal resistance of 180 K/W on standard PCB pads.
Technical Context
This device operates as a single-channel unidirectional TVS diode with avalanche breakdown behavior, triggered by reverse-biased overvoltage events. Its low incremental surge resistance ensures minimal voltage overshoot during fast transients, while its "Low Noise" technology enables sub-nanosecond response to ESD pulses per IEC 61000-4-2.
The SMF5V0A-HM3_A08 is rated for 200 W peak pulse power (10/1000 μs), 1000 W (8/20 μs), and supports continuous operation from –65 °C to +175 °C. It meets AEC-Q101 stress test requirements for human body model (>8 kV) and is qualified for automotive and harsh-environment industrial use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 5.0 V - defines maximum continuous operating voltage before clamping begins |
| Clamping Voltage (VC) | 9.2 V at IPPM = 21.7 A - limits downstream IC voltage during surge, protecting 5 V logic rails |
| Peak Pulse Current (IPPM) | 21.7 A (10/1000 μs) - sustains industry-standard lightning/surge test levels without failure |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds Level 4 system-level ESD robustness requirement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/5A | Higher clamping voltage (13.4 V), larger SMA (DO-214AC) package (4.5 mm × 2.7 mm) | Less suitable for space-constrained USB/HDMI layouts; better for higher-power 24 V industrial lines | Select when board area allows larger footprint and higher VC is acceptable for 5 V rail margin |
| TPD2E001DRYR | Bi-directional, dual-channel, 15 pF capacitance, 5.5 V standoff - integrated ESD array in SOT-553 | Designed for high-speed digital buses (e.g., I²C, GPIO); not rated for AEC-Q101 or >200 W surge | Prefer for compact multi-line protection where low capacitance and small size outweigh surge rating needs |
Compared with SMAJ5.0A-E3/5A and TPD2E001DRYR, the SMF5V0A-HM3_A08 delivers optimal balance of low-profile packaging, AEC-Q101 qualification, and 200 W surge capability - making it the preferred choice for automotive and industrial 5 V interface protection where board space and reliability are jointly constrained.

FAQ
What is the clamping voltage of SMF5V0A-HM3_A08 at its rated peak pulse current?
The SMF5V0A-HM3_A08 has a maximum clamping voltage (VC) of 9.2 V at 21.7 A peak pulse current (10/1000 μs waveform). This value is measured under standardized surge conditions and ensures that downstream 5 V logic circuits remain within safe operating limits during transient events. The SMF5V0A-HM3_A08 achieves this with low incremental surge resistance, minimizing voltage overshoot beyond the specified VC.
Is SMF5V0A-HM3_A08 qualified to AEC-Q101, and what does that qualification cover?
Yes, SMF5V0A-HM3_A08 is AEC-Q101 qualified, covering stress tests including human body model ESD (>8 kV), temperature cycling, high-temperature operating life, and mechanical shock. This qualification confirms suitability for automotive applications such as body control modules, infotainment interfaces, and LIN bus nodes where reliability under thermal and electrical stress is critical. The SMF5V0A-HM3_A08 maintains full specification compliance across –65 °C to +175 °C operating range.
Can SMF5V0A-HM3_A08 be used on bidirectional signal lines like I²C or RS-485?
No - SMF5V0A-HM3_A08 is a unidirectional TVS diode intended for protection of positive-rail referenced signals (e.g., 5 V USB D+, HDMI DDC SDA). It does not protect against negative-going transients on bidirectional lines. For I²C or RS-485, a bidirectional device such as SMBJ5.0CA or dedicated ESD arrays like TPD2E001DRYR is required. Using SMF5V0A-HM3_A08 on truly bidirectional paths may result in forward conduction during negative surges, risking damage or malfunction.
What is the moisture sensitivity level (MSL) and reflow profile for SMF5V0A-HM3_A08?
The SMF5V0A-HM3_A08 has a moisture sensitivity level (MSL) of 1 per J-STD-020, meaning it is not humidity-sensitive and can be stored indefinitely at ambient conditions without baking. Its reflow profile permits peak temperatures up to 260 °C, compatible with standard lead-free soldering processes. The DO-219AB package uses UL 94 V-0 flame-retardant molding compound and supports both wave and reflow soldering - verified in Vishay's qualification testing for SMF5V0A-HM3_A08.
How does the 1120 pF capacitance of SMF5V0A-HM3_A08 affect high-speed signal integrity?
The 1120 pF typical capacitance (at 0 V, 1 MHz) of SMF5V0A-HM3_A08 limits usable bandwidth to ~140 MHz, making it appropriate for USB 2.0 (480 Mbps) and HDMI DDC (100 kHz) but unsuitable for USB 3.x (5 Gbps), HDMI TMDS (up to 3.4 Gbps), or PCIe Gen 2+. Signal degradation manifests as reduced edge rate and increased jitter; designers must verify eye diagram margins in final layout. The SMF5V0A-HM3_A08 prioritizes surge robustness over ultra-low capacitance - a deliberate trade-off for industrial and automotive environments.
