Microchip Technology JANTXV1N5653A

Overview

JANTXV1N5653A from Microchip Technology is a hermetically sealed, unidirectional transient voltage suppressor (TVS) diode in DO-13 metal package, designed for high-reliability military avionics and industrial systems. It features 61.2 V minimum breakdown voltage (V_BR), 55.1 V rated standoff voltage (V_WM), 98.0 V maximum clamping voltage (V_C) at 15.3 A peak pulse current (I_PP), and 1500 W peak pulse power rating at 10/1000 µs waveform.

For engineers reviewing the JANTXV1N5653A datasheet, JANTXV1N5653A pinout, JANTXV1N5653A application, or JANTXV1N5653A equivalent, this device serves as a MIL-PRF-19500/500 qualified protection component for inductive switching transients, ESD per IEC 61000-4-2, EFT per IEC 61000-4-4, and secondary lightning surges per IEC 61000-4-5 with 2–42 Ω source impedance.

Technical Context

The JANTXV1N5653A operates as a unidirectional avalanche diode, entering controlled breakdown when transient voltage exceeds its 55.1 V standoff threshold. Its response time is under 100 ps, enabling sub-nanosecond clamping of fast-rising threats such as ESD and inductive kickback.

It is rated for 1500 W non-repetitive peak pulse power at 25 °C lead temperature, with thermal resistance of 50 °C/W junction-to-lead and full operational capability across –55 °C to +175 °C ambient range. The DO-13 package ensures hermetic sealing and radiation hardness per MicroNote 050.

FAQ

What is the standoff voltage (V_WM) of the JANTXV1N5653A?

The JANTXV1N5653A has a rated standoff voltage (V_WM) of 55.1 V, meaning it remains non-conductive up to this reverse voltage level under normal operating conditions. This value is selected to exceed typical 28 V or 48 V system rails while providing sufficient margin before avalanche onset at 61.2 V. Designers must ensure V_WM is greater than the circuit's maximum continuous operating voltage to prevent leakage or premature conduction.

Does the JANTXV1N5653A meet IEC 61000-4-5 for lightning surge immunity?

Yes, the JANTXV1N5653A is validated for secondary lightning surge protection per IEC 61000-4-5 with source impedances of 2 Ω, 12 Ω, and 42 Ω. Specifically, it supports Class 4 (42 Ω) up to 1N5648A, and Class 2 (2 Ω) up to 1N5642A-placing JANTXV1N5653A within Class 2 for 2 Ω and Class 3 for 42 Ω testing. Its 1500 W peak pulse rating and 98.0 V clamping ensure compliance when properly mounted with low-inductance grounding.

Is the JANTXV1N5653A pin-compatible with other DO-13 TVS diodes?

The JANTXV1N5653A uses standard DO-13 (DO-202AA) mechanical dimensions and axial lead configuration, making it mechanically compatible with all DO-13 packaged diodes. However, electrical compatibility depends on V_WM, V_C, and I_PP-for example, JANTXV1N5652A shares the same package but differs in standoff and clamping voltages. PCB layout reuse is possible, but circuit validation is required due to parameter variation across the series.

What is the thermal resistance specification for the JANTXV1N5653A?

The JANTXV1N5653A has a junction-to-lead thermal resistance (R_θJL) of 50 °C/W when measured at 0.375 inches (10 mm) from the case body. When mounted on an FR4 PCB with 4 mm² copper pads (1 oz), its junction-to-ambient resistance rises to 110 °C/W. This informs heatsinking decisions: for sustained surge duty, keep lead temperature ≤125 °C using appropriate copper area and airflow, as DC power dissipation is limited to 1 W at that temperature.

How does the JANTXV1N5653A perform under extreme temperature conditions?

The JANTXV1N5653A operates across –55 °C to +175 °C, with specified electrical parameters guaranteed at 25 °C and derated performance outside that range. Its breakdown voltage exhibits a temperature coefficient of +0.104 %/°C, meaning V_BR increases predictably with temperature-critical for high-temperature downhole or engine bay applications. The hermetic DO-13 package prevents parametric shift due to humidity or oxidation over decades of service.
