Product details
Overview
VTVS23GSMF-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 22.6 V maximum stand-off voltage (VRWM), 26.51–27.60 V reverse breakdown voltage (VBR) at 1 mA, and clamps to ≤38 V at 10.4 A peak pulse current (10/1000 μs), with ±2 % VBR tolerance and IEC 61000-4-2 ±30 kV contact/air discharge compliance.
For engineers reviewing the VTVS23GSMF-HM3-08 datasheet, VTVS23GSMF-HM3-08 pinout, VTVS23GSMF-HM3-08 application, or VTVS23GSMF-HM3-08 equivalent, key selection criteria include its 22.6 V working voltage, 38 V clamping performance at 10.4 A, halogen-free SMF package compatibility with SOD-123W outline, AEC-Q101 qualification option, and 175 °C junction temperature rating for automotive and industrial environments.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its precisely specified breakdown range (26.51–27.60 V). Its low dynamic impedance ensures rapid clamping response (<1 ns) under transient stress, minimizing voltage overshoot on protected lines.
The SMF package enables high thermal dissipation (RthJL = 20 K/W) and supports wave/reflow soldering per J-STD-020 MSL level 1. Halogen-free molding compound and tin-plated terminations meet RoHS and automotive material compliance requirements.

|---|---|
Use Scenario: Protecting 24 V supply lines feeding ABS wheel speed sensors exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor VCC and chassis ground to clamp transients before they reach ASIC front-end. Use Value: 22.6 V VRWM allows full operation across cold-crank (6 V) to load-dump (35 V) conditions while clamping to ≤38 V prevents damage to 30 V-rated sensor ICs. |
Use Scenario: ESD and surge protection on CAN_H/CAN_L differential pair in factory automation PLC I/O module. IC Role / Device Role / Timing Role: One VTVS23GSMF-HM3-08 per line (CAN_H to GND, CAN_L to GND) providing bidirectional protection via two unidirectional devices. Use Value: ±30 kV ESD immunity and 400 W surge rating ensure robustness against operator touch events and nearby relay switching noise in harsh industrial settings. |
| Smart Meter Power Input | Medical Patient Monitor Signal Line |
Use Scenario: Protecting 24 V auxiliary power input of utility smart meters subjected to lightning-induced surges on distribution lines. IC Role / Device Role / Timing Role: First-stage clamping device upstream of DC/DC converter, absorbing bulk energy before secondary TVS or MOV stages. Use Value: 175 °C TJ max and 400 W PPPM enable reliable operation inside sealed, thermally constrained meter enclosures during sustained overvoltage events. |
Use Scenario: Safeguarding analog front-end inputs (e.g., ECG lead connections) against electrostatic discharge during clinical handling. IC Role / Device Role / Timing Role: Low-capacitance (480 pF) unidirectional TVS placed between patient-connected electrode trace and instrumentation amplifier input. Use Value: Clamping to ≤38 V within nanoseconds prevents latch-up or gate oxide damage in precision op-amps while maintaining signal integrity for sub-mV biopotential measurements. |
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 VRWM; 38.9 V VC @ 10.3 A; SMA package (larger footprint) | Higher VBR variation reduces coordination margin in tightly regulated systems; larger package limits high-density layouts | Select when cost sensitivity outweighs precision clamping and board space constraints |
| SMCJ24A | Same ±5 % VBR; 24 V VRWM; 38.9 V VC @ 10.3 A; SMC package (higher power, larger size) | Rated for 1500 W peak power but over-specified for 400 W needs; incompatible with SMF footprint | Choose only if legacy design uses SMC and future redesign to SMF is not planned |
Compared with SMAJ24A and SMCJ24A, VTVS23GSMF-HM3-08 delivers tighter ±2 % VBR control, smaller DO-219AB footprint, and halogen-free construction-making it optimal for new automotive and space-constrained industrial designs requiring precise, compact, and compliant surge protection.

FAQ
What is the exact breakdown voltage range for VTVS23GSMF-HM3-08?
The VTVS23GSMF-HM3-08 has a reverse breakdown voltage (VBR) range of 26.51 V to 27.60 V at IT = 1 mA and TJ = 25 °C, with ±2 % tolerance confirmed in Vishay's official datasheet (Doc. #85891, Rev. 2.2). This tight tolerance enables precise coordination with downstream overvoltage protection circuits in automotive and industrial applications.
Is VTVS23GSMF-HM3-08 AEC-Q101 qualified?
VTVS23GSMF-HM3-08 is offered in an AEC-Q101 qualified version (denoted by "H" in the ordering code), verified per stress test requirements for automotive discrete semiconductors. The "H" suffix in VTVS23GSMF-HM3-08 explicitly indicates qualification for use in automotive electronics such as body control modules and sensor interfaces.
What does the "HM3-08" suffix mean in VTVS23GSMF-HM3-08?
In VTVS23GSMF-HM3-08, "H" denotes AEC-Q101 qualification, "M3" indicates halogen-free, RoHS-compliant, lead (Pb)-free terminations with tin plating, and "-08" specifies packaging in 3 k per 7″ reel (8 mm tape, MOQ = 30 k units). This full suffix defines environmental compliance, reliability grade, and logistics configuration.
Can VTVS23GSMF-HM3-08 be used for bidirectional protection?
No-VTVS23GSMF-HM3-08 is a unidirectional TVS diode, intended for protection of positive-polarity DC lines only. For bidirectional protection (e.g., data lines like RS-485), two VTVS23GSMF-HM3-08 devices must be used in series opposition, or a dedicated bidirectional part such as VTVS23BGMF-HM3-08 should be selected instead.
What is the thermal resistance and maximum junction temperature of VTVS23GSMF-HM3-08?
VTVS23GSMF-HM3-08 has a thermal resistance RthJL of 20 K/W (junction-to-lead, mounted on infinite heat sink) and a maximum junction temperature (TJ) of +175 °C. These ratings allow reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 105 °C.
