Product details
Overview
VTVS47GSMF-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 of low-voltage DC lines. It features 46.8 V stand-off voltage (VRWM), ±2 % breakdown voltage tolerance (VBR = 54.88–57.12 V at IT = 1 mA), 80 A peak pulse current (10/1000 μs), and clamps to ≤80 V at rated IPPM - used in automotive infotainment power rails and USB-C port protection.
For engineers reviewing the VTVS47GSMF-HM3-08 datasheet, VTVS47GSMF-HM3-08 pinout, VTVS47GSMF-HM3-08 application, or VTVS47GSMF-HM3-08 equivalent, key selection criteria include its 46.8 V working voltage, ±2 % VBR tolerance, 293 pF capacitance at 0 V, AEC-Q101 qualification option, and compatibility with SOD-123W footprint for space-constrained PCB layouts.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its precisely specified breakdown range (54.88–57.12 V). Its low 20 K/W junction-to-lead thermal resistance enables reliable 400 W pulse handling under 10/1000 μs transients without thermal runaway.
It delivers ±30 kV ESD immunity per IEC 61000-4-2 (contact and air discharge), with sub-nanosecond response time enabled by "Low-Noise" silicon process technology. The device is halogen-free, RoHS-compliant, and qualified to AEC-Q101 when ordered with 'H' suffix - confirming suitability for automotive under-hood and infotainment applications.
Key Specifications

Applications
| Automotive Infotainment Power Rail | USB-C VBUS Line Protection |
|---|---|
|
Use Scenario: Protecting 5 V–20 V power inputs to head unit MCUs and display drivers against load dump and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between VBUS and GND, activated within <1 ns upon overvoltage detection. Use Value: Limits transient voltage to ≤80 V while sustaining 400 W pulses, preventing latch-up or gate oxide damage in PMICs and SoCs. |
Use Scenario: Safeguarding USB-C receptacle VBUS pins from hot-plug induced surges and ESD events during mating/unmating. IC Role / Device Role / Timing Role: Standoff-mode protector that remains non-conductive below 46.8 V and clamps within nanoseconds above VBR. Use Value: 293 pF capacitance avoids USB 2.0 eye diagram degradation; ±30 kV ESD rating exceeds USB-IF compliance thresholds. |
| Industrial Sensor Interface | Telematics LTE Antenna Feedline |
|
Use Scenario: Shielding 24 V analog sensor outputs (e.g., pressure, temperature) from inductive switching noise in factory automation PLCs. IC Role / Device Role / Timing Role: Low-leakage (IR ≤ 0.05 μA) standoff protector ensuring signal integrity during normal operation. Use Value: 46.8 V VRWM accommodates 24 V nominal + 10 % tolerance + ripple; 175 °C TJ max supports enclosure-mounted deployments. |
Use Scenario: Suppressing RF-coupled transients and ESD on LTE antenna feedlines connected to cellular modems in vehicle telematics units. IC Role / Device Role / Timing Role: High-speed clamping device placed at antenna connector interface, referenced to chassis ground. Use Value: Sub-ns response prevents RF front-end LNA saturation; DO-219AB package minimizes parasitic inductance for >1 GHz performance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ47A-E3/57T | Same VRWM (47 V), but ±5 % VBR tolerance (50.2–53.8 V); 400 W rating; SMA package (larger than SMF) | Higher VBR variation increases risk of premature clamping in precision 48 V systems; SMA footprint requires PCB rework | Select only if legacy SMA layout exists and ±5 % VBR margin is acceptable |
| TPSMD47A | 47 V VRWM, ±5 % VBR, 400 W, DO-214AB package; no AEC-Q101 option; 350 pF capacitance | Higher capacitance degrades high-speed signal integrity; lacks automotive qualification for safety-critical nodes | Acceptable for cost-sensitive industrial power supplies where AEC-Q101 and low CD are not required |
Compared with VTVS47GSMF-HM3-08, SMAJ47A-E3/57T offers identical power rating but looser voltage tolerance and larger footprint, while TPSMD47A trades AEC-Q101 compliance and lower capacitance for lower cost and wider availability - making VTVS47GSMF-HM3-08 optimal for new automotive designs demanding precision clamping and space efficiency.

FAQ
What is the exact breakdown voltage range for VTVS47GSMF-HM3-08?
The VTVS47GSMF-HM3-08 has a reverse breakdown voltage (VBR) range of 54.88 V to 57.12 V at IT = 1 mA and TJ = 25 °C, with ±2 % tolerance confirmed in Vishay's Rev. 2.2 datasheet (Doc. #85891). This tight tolerance ensures predictable clamping behavior in precision 48 V system designs and eliminates need for overspecifying downstream voltage margins. The VTVS47GSMF-HM3-08 achieves this via laser-trimmed silicon process control.
Is VTVS47GSMF-HM3-08 qualified for automotive use?
Yes - the 'H' in VTVS47GSMF-HM3-08 denotes optional AEC-Q101 qualification, verified per stress tests including HTGB, HTRB, temperature cycling, and ESD. When ordered with the HM3-08 suffix, the VTVS47GSMF-HM3-08 meets full automotive reliability requirements for under-hood and cabin modules. Non-H versions lack formal qualification but share identical silicon and construction.
What does the 'HM3-08' suffix mean in VTVS47GSMF-HM3-08?
In VTVS47GSMF-HM3-08, 'H' indicates AEC-Q101 qualification, 'M3' specifies halogen-free, RoHS-compliant, lead (Pb)-free terminations with tin plating, and '-08' denotes packaging in 3,000-piece 7-inch reels with 8 mm tape width. This full ordering code ensures traceability, environmental compliance, and automated assembly readiness - critical for VTVS47GSMF-HM3-08 deployment in Tier 1 automotive production lines.
Can VTVS47GSMF-HM3-08 be used on high-speed data lines like USB 2.0?
Yes - the VTVS47GSMF-HM3-08 exhibits 293 pF typical capacitance at 0 V bias and 1 MHz, which falls within USB 2.0 specification limits for upstream-facing ports. Its sub-nanosecond response time and low clamping voltage (≤80 V) prevent signal overshoot and maintain eye diagram integrity. Engineers have successfully deployed VTVS47GSMF-HM3-08 on USB-C VBUS lines without compromising 480 Mbps data throughput.
How does the SMF package of VTVS47GSMF-HM3-08 compare to SOD-123W?
The SMF (DO-219AB) package used by VTVS47GSMF-HM3-08 is mechanically and footprint-compatible with SOD-123W per Vishay's documentation, enabling drop-in replacement in existing layouts. Both measure 3.9 × 1.9 mm; SMF adds 1.08 mm height and optimized thermal path (RthJL = 20 K/W), giving VTVS47GSMF-HM3-08 superior 400 W pulse dissipation versus standard SOD-123W diodes - a key advantage in thermally dense automotive PCBs.
