Product details
Overview
VTVS23GSMF-HM3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, with 22.6 V maximum stand-off voltage, 26.51–27.60 V reverse breakdown voltage at 1 mA, and 38 V maximum clamping voltage at 10.4 A peak pulse current; used for ESD and surge protection on automotive power rails and industrial I/O lines.
For engineers reviewing the VTVS23GSMF-HM3-18 datasheet, VTVS23GSMF-HM3-18 pinout, VTVS23GSMF-HM3-18 application, or VTVS23GSMF-HM3-18 equivalent, key selection criteria include ±2 % VBR tolerance, 10/1000 μs waveform compliance, ±30 kV IEC 61000-4-2 ESD rating, 175 °C max junction temperature, and halogen-free SOD-123W-compatible packaging.
Technical Context
This device operates as a unidirectional avalanche diode, triggering at precisely defined reverse breakdown voltage to clamp transients before downstream circuitry sustains damage. Its low-noise fast-response architecture achieves sub-nanosecond turn-on under ESD stress while maintaining stable clamping performance across -55 °C to +175 °C.
The SMF package enables high thermal dissipation (RthJL = 20 K/W) and supports both wave and reflow soldering per J-STD-020 MSL level 1. It is qualified to AEC-Q101 and meets IEC 61000-4-2 for ±30 kV contact/air discharge - critical for automotive body electronics and industrial sensor interfaces.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 24 V supply inputs in body control modules against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between VBAT and chassis ground to clamp surges above 22.6 V. Use Value: Limits clamped voltage to ≤38 V during 10.4 A transients, preventing damage to LDOs and microcontrollers rated for 40 V absolute max. |
Use Scenario: Safeguarding analog outputs of pressure sensors in factory automation PLCs exposed to cable-induced surges. IC Role / Device Role / Timing Role: Standoff protection element on 4–20 mA loop outputs, absorbing induced transients before op-amp output stages. Use Value: 480 pF capacitance avoids signal distortion at loop bandwidths up to 10 kHz; ±30 kV ESD rating prevents field failures during maintenance. |
| USB-C Port ESD Clamping | Motor Drive Gate Driver Protection |
|
Use Scenario: Secondary ESD protection on USB-C VBUS lines after primary common-mode choke filtering. IC Role / Device Role / Timing Role: Fast-response unidirectional clamp referenced to system ground, triggered within <1 ns of ESD event. Use Value: Tight ±2 % VBR ensures clamping initiates reliably at 22.6 V, avoiding false triggering during normal 20 V VBUS operation. |
Use Scenario: Protecting high-side gate driver ICs from Miller-induced voltage spikes during MOSFET switching in BLDC inverters. IC Role / Device Role / Timing Role: Snubber-style clamping device across gate-to-source terminals to suppress dv/dt overshoot. Use Value: 38 V clamping voltage prevents gate oxide breakdown in 30 V-rated drivers; 175 °C rating matches motor controller thermal environment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | ±5 % VBR tolerance; 24 V nominal VRWM; same SMF package but non-AEC-Q101 | Lacks automotive qualification; higher VBR variation increases risk of premature clamping in precision systems | Select when cost sensitivity outweighs AEC-Q101 requirement and ±5 % tolerance is acceptable |
| TPSMD24A | 24 V VRWM; ±5 % VBR; 400 W PPPM; SMC package (larger footprint, higher RthJA) | Requires PCB layout change due to SMC (DO-214AB) vs. SMF (DO-219AB); less suitable for space-constrained automotive ECUs | Choose only if existing design uses SMC footprint and thermal budget allows higher junction rise |
Compared with SMAJ24A and TPSMD24A, VTVS23GSMF-HM3-18 delivers tighter ±2 % breakdown tolerance, AEC-Q101 qualification, and optimized SMF packaging - making it preferred for next-generation automotive and industrial designs where precision clamping and reliability are non-negotiable.

FAQ
What is the exact reverse breakdown voltage range for VTVS23GSMF-HM3-18?
The VTVS23GSMF-HM3-18 has a reverse breakdown voltage (VBR) of 26.51 V minimum to 27.60 V maximum at 1 mA test current and 25 °C ambient, reflecting its ±2 % tolerance grade as specified in Vishay's Document 85891 Rev. 2.2.
Is VTVS23GSMF-HM3-18 qualified for automotive applications?
Yes, VTVS23GSMF-HM3-18 is AEC-Q101 qualified, confirming its suitability for automotive applications including body electronics, infotainment power supplies, and ADAS sensor interfaces where reliability under thermal cycling and vibration is mandatory.
What does the "HM3-18" suffix indicate in VTVS23GSMF-HM3-18?
The "HM3-18" suffix denotes halogen-free, lead-free terminations (H), tape-and-reel packaging (M3), and 10k per 13″ reel (18). This matches Vishay's ordering code convention in Document 85891 for RoHS-compliant, high-volume production-ready reels.
Can VTVS23GSMF-HM3-18 be used in bidirectional protection configurations?
No - VTVS23GSMF-HM3-18 is a unidirectional TVS diode. For bidirectional protection, Vishay offers complementary parts like VTVS23GSMF-BI or dual-diode configurations; using this part in reverse-biased mode would not provide symmetrical clamping.
What is the thermal resistance from junction to lead (RthJL) for VTVS23GSMF-HM3-18?
The thermal resistance from junction to lead (RthJL) for VTVS23GSMF-HM3-18 is 20 K/W when mounted on an infinite heat sink, enabling effective power dissipation during repetitive surge events without exceeding the 175 °C maximum junction temperature.
