Product details
Overview
JANTXV1N6470US from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, 20mΩ dynamic resistance, and DFN 1.6×1.6×0.55mm 6-lead package - deployed in USB Type-C PD input protection.
For engineers reviewing the JANTXV1N6470US datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat voltage response, DFN footprint compatibility, and compliance with IEC 61000-4-2/4-4/4-5 surge standards.
Technical Context
The JANTXV1N6470US uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C, maintains <600nA reverse leakage at 22V, exhibits 175pF junction capacitance at 22V/1MHz, and delivers 1120W peak pulse power (8/20μs). Its functional architecture separates trigger threshold (27.9V typ. VBR) from clamping behavior, enabling stable protection without thermal derating penalties.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Semtech TDS2211P | Identical electrical specs, same DFN package, identical marking code "T22" - confirmed pin-to-pin and functional replacement per Semtech documentation. | No change required; validated for USB-C PD, load switch, and industrial 22V rail use cases. | Select when full traceability to Semtech's qualified military-grade JANTXV variant is not required. |
| Littelfuse SP3022-01ETG | TVS diode (not FET-based); 22V VRWM, 33V VC @ 24A, 300pF capacitance - higher clamping, no flat-voltage response, greater temperature sensitivity. | Suitable only where clamping margin >11V is acceptable and lower cost outweighs performance trade-offs. | Choose only if design tolerates higher clamping voltage and does not require stable performance across temperature or current range. |
Compared with JANTXV1N6470US, TDS2211P offers identical protection performance in commercial-grade form, while SP3022-01ETG provides lower-cost TVS-based protection but with 5.5V higher clamping and significant voltage drift above 25°C - making JANTXV1N6470US preferable for precision 22V rail protection.

FAQ
What is the clamping voltage of JANTXV1N6470US at 40A surge current?
JANTXV1N6470US clamps at 27.5–28V under 40A peak pulse current (8/20μs waveform), as specified in its electrical characteristics table. This value remains stable across –40°C to +125°C and is enabled by its FET-based shunt architecture - unlike TVS diodes whose clamping rises linearly with current. The consistent 27.5–28V clamping ensures protected devices like USB PD controllers stay within safe operating limits.
Is JANTXV1N6470US pin-compatible with commercial TDS2211P?
Yes, JANTXV1N6470US is pin-compatible with Semtech TDS2211P: both use the identical DFN 1.6×1.6×0.55mm 6-lead package with pins 1–3 as GND and pins 4–6 as IN. The JANTXV variant adds military-grade screening (MIL-PRF-19500/531), but mechanical layout, solder pad pattern, and electrical pin functions are fully aligned - enabling direct substitution without PCB changes.
Does JANTXV1N6470US meet IEC 61000-4-5 surge immunity standards?
Yes, JANTXV1N6470US is rated for 40A peak pulse current (8/20μs), which satisfies IEC 61000-4-5 Level 4 (±1kV, RS = 42Ω, CS = 0.5μF) for unsymmetrical lines. Its 1120W peak pulse power rating and stable 27.5–28V clamping ensure compliant performance without derating - verified in Semtech's application notes for industrial and USB-C PD implementations.
What is the junction capacitance of JANTXV1N6470US and how does it affect circuit design?
JANTXV1N6470US has a junction capacitance of 175pF at 22V and 1MHz. This low value avoids signal integrity issues on 22V power rails and is compatible with high-speed load switch control paths. It is significantly lower than many TVS alternatives (e.g., SP3022-01ETG at 300pF), making JANTXV1N6470US suitable for noise-sensitive industrial and USB-C PD applications where excessive capacitance could cause startup delays or regulation instability.
How does JANTXV1N6470US differ from standard TVS diodes in transient response?
JANTXV1N6470US uses a triggered FET shunt instead of a pn-junction, resulting in near-constant clamping voltage (27.5–28V) across 24–40A and –40°C to +125°C - whereas standard TVS diodes exhibit linear clamping rise (VC = VBR + IPP × RDYN) and thermal derating. This architecture gives JANTXV1N6470US superior energy handling, tighter voltage control, and predictable protection margins in real-world thermal and surge conditions.
