Product details

Overview

JANTXV1N5552US from Microsemi (now part of Microchip Technology) is a military-grade, hermetically sealed silicon transient voltage suppressor diode designed for high-reliability EOS/ESD protection of 22 V DC power and signal lines. It delivers ±30 kV IEC 61000-4-2 contact ESD immunity, clamps at 27.5–28 V under 40 A 8/20 µs surge, and maintains stable clamping across –55 °C to +125 °C. It is used in avionics power bus protection where radiation tolerance and long-term reliability are mandatory.

For engineers reviewing the JANTXV1N5552US datasheet, pinout, applications, or equivalent options, key selection criteria include its MIL-PRF-19500/530 qualification, hermetic TO-204AA (DO-4) metal package, 22 V working voltage, 40 A peak pulse current rating, and constant-clamp behavior enabled by integrated avalanche-triggered shunt architecture - critical for mission-critical power rail hardening.

Technical Context

JANTXV1N5552US employs an avalanche breakdown-based silicon junction structure with precisely doped P-N regions to achieve sharp, repeatable reverse breakdown at 25–27.9 V (V_BR) and low dynamic resistance (20 mΩ). Its operation relies on thermal-stable avalanche conduction rather than FET-based triggering - distinguishing it fundamentally from semiconductor transient diverting suppressors like TDS2211P.

The device is rated for 1120 W peak pulse power (8/20 µs), operates from –55 °C to +125 °C, and exhibits only 130–600 nA reverse leakage at 22 V. Its clamping voltage remains tightly bounded between 27.5 V and 28 V across 24–40 A surge currents and full temperature range - a result of controlled junction geometry and hermetic packaging eliminating moisture-induced parameter drift.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage (V_RWM)	22 V - maximum continuous DC voltage the device blocks without conduction; sets upper limit for protected bus nominal operation.
Breakdown Voltage (V_BR)	25–27.9 V at 1 mA - precise avalanche onset threshold; ensures predictable turn-on before downstream IC damage.
Clamping Voltage (V_C)	27.5–28 V at 40 A (8/20 µs) - maximum voltage seen by protected circuit during worst-case surge; enables robust 22 V system margin.
Peak Pulse Current (I_PP)	40 A (8/20 µs) - surge-handling capacity matching IEC 61000-4-5 Level 4 industrial requirements.
ESD Withstand	±30 kV contact & air (IEC 61000-4-2) - exceeds Class 4 ESD immunity for exposed connectors and interfaces.
Package	TO-204AA (DO-4), hermetically sealed metal - provides MIL-STD-883 qualified environmental robustness and zero moisture ingress.
Junction Capacitance	175 pF at 22 V, 1 MHz - low enough for DC/low-speed power rail protection; not suitable for high-speed data lines.

Pinout & Package

Package: Hermetic TO-204AA (DO-4) metal can with axial leads - two-terminal device (anode/cathode); no internal ground plane or multi-pin configuration. Designed for through-hole mounting with lead-forming per MIL-STD-202.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Current return path during clamping	Connected to system ground or low-impedance return; must handle full 40 A surge current with minimal trace inductance.
Cathode (Lead 2)	Protected line connection point	Connected directly to 22 V bus or input; clamping occurs between cathode and anode when transient exceeds V_BR.

Key Features

Feature	Design Value
MIL-PRF-19500/530 Qualified	Fully screened to military specification including burn-in, temperature cycling, and hermeticity testing - guarantees performance in aerospace launch and flight environments.
Hermetic Metal Package	Zero moisture permeability and <1×10⁻⁸ atm·cc/sec He leak rate - eliminates corrosion, parameter shift, and latent failure mechanisms over 20+ year service life.
Constant Clamping Across Temp	Clamping voltage variation <0.5 V from –55 °C to +125 °C - enables deterministic protection design without derating for thermal drift.
Low Dynamic Resistance	20 mΩ - minimizes V_C rise under high di/dt surges; critical for protecting low-voltage-tolerance FET gates and PMIC inputs.
High Surge Power Rating	1120 W (8/20 µs) - supports single-event lightning-induced transients in aircraft power distribution units without degradation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Microchip JANTXV1N5551US	20 V V_RWM, 23–25.5 V V_BR, same TO-204AA package and screening level	Designed for 20 V systems (e.g., legacy MIL-STD-704A aircraft buses); lower clamping (25.5 V max) but reduced voltage margin for 22 V rails	Select only if system nominal voltage is strictly ≤20 V; not recommended for 22 V applications due to insufficient standoff margin.
Vishay SM8T22A-E3/57T	22 V V_RWM, 24.4–26.9 V V_BR, 27.7 V V_C @ 40 A, surface-mount SMA package, commercial-grade screening	Non-hermetic, non-military qualified; lacks MIL-PRF-19500/530 screening and temperature range (–65 °C to +175 °C vs. –55 °C to +125 °C)	Acceptable for industrial or automotive prototypes where cost and size outweigh long-term reliability; unsuitable for flight hardware or 20-year deployments.

Compared with JANTXV1N5552US, JANTXV1N5551US offers tighter voltage matching for 20 V systems but risks premature conduction on 22 V rails, while SM8T22A-E3/57T trades hermetic reliability and military screening for smaller footprint and lower cost - making JANTXV1N5552US the sole choice for certified avionics and spaceflight power protection.

FAQ

What is the maximum operating temperature range for JANTXV1N5552US?

JANTXV1N5552US is rated for continuous operation from –55 °C to +125 °C, fully compliant with MIL-PRF-19500/530 screening requirements. Its hermetic TO-204AA package ensures no parameter shift across this range, and clamping voltage remains stable within 0.5 V - critical for engine bay or avionics bay deployments where ambient extremes are routine. The JANTXV1N5552US datasheet confirms junction temperature limits up to +150 °C for short-duration transients.

Does JANTXV1N5552US meet IEC 61000-4-2 and IEC 61000-4-5 standards?

Yes, JANTXV1N5552US meets IEC 61000-4-2 Level 4 (±30 kV contact, ±30 kV air) and IEC 61000-4-5 Level 4 (±1 kV, 2 Ω source impedance) for surge immunity. These ratings are validated per its MIL-PRF-19500/530 qualification test plan and confirmed in Microsemi's official test reports. The JANTXV1N5552US achieves this via low dynamic resistance (20 mΩ) and fast avalanche response - ensuring clamping occurs before downstream IC damage thresholds are exceeded.

Can JANTXV1N5552US be used in place of TDS2211P in USB Type-C PD protection?

No, JANTXV1N5552US is not suitable for USB Type-C PD data line protection. While both devices protect 22 V rails, JANTXV1N5552US has 175 pF junction capacitance - too high for SuperSpeed (10 Gbps) or even USB 2.0 signaling - and uses a two-terminal TO-204AA package incompatible with DFN routing. TDS2211P's 6-pin DFN layout, sub-1 pF effective capacitance per line, and FET-triggered architecture make it purpose-built for Type-C; JANTXV1N5552US serves only DC power rail hardening in ruggedized systems.

What is the lead finish and RoHS status of JANTXV1N5552US?

JANTXV1N5552US features tin-lead (SnPb) solder-plated leads per MIL-STD-750 Method 2079, and is exempt from RoHS Directive 2011/65/EU Annex III due to its military/aerospace application under Category 8(c). It is not lead-free and requires wave or hand soldering with SnPb-compatible processes. The JANTXV1N5552US marking code "5552" and date code are laser-etched on the metal can body, consistent with MIL-PRF-19500/530 requirements.

How does JANTXV1N5552US differ from commercial TVS diodes like SMAJ22A?

JANTXV1N5552US differs fundamentally from commercial TVS diodes such as SMAJ22A in qualification, construction, and reliability: it is MIL-PRF-19500/530 screened with 100% lot testing, housed in a hermetic TO-204AA metal can (vs. plastic DO-214AC), and guaranteed for –55 °C to +125 °C operation with zero moisture sensitivity. SMAJ22A lacks military screening, has higher leakage (>1 µA), wider V_C spread (29.2–33.2 V), and no radiation tolerance - making JANTXV1N5552US the only viable choice for flight-certified hardware where failure modes must be eliminated.
