Product details
Overview
JANTXV1N6133US/TR from Microsemi (now Microchip) is a military-grade 1.5 kW transient voltage suppression diode rated for 33 V standoff voltage, 53.3 V clamping voltage at 38.3 A peak pulse current, and 1.5 kW peak pulse power per MIL-STD-19500/211. It protects DC power rails in avionics power supplies against ESD and lightning-induced surges.
For engineers reviewing the JANTXV1N6133US/TR datasheet, JANTXV1N6133US/TR pinout, JANTXV1N6133US/TR application, or JANTXV1N6133US/TR equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current capability under IEC 61000-4-5 waveform 3, and hermetic TO-204AD (DO-201AD) package suitability for high-reliability aerospace environments.
Technical Context
This device operates as a unidirectional avalanche breakdown TVS diode with fast response time (<1.0 ps) and low dynamic impedance (0.4 Ω typical). Its junction capacitance is 120 pF at 0 V, and leakage current is ≤1 μA at 26.7 V.
Designed for single-line DC rail protection, it complies with MIL-PRF-19500/211 Class V screening and meets DO-160 Section 22 Level 3 lightning surge requirements when used with appropriate series impedance.

FAQ
What is the maximum operating temperature for JANTXV1N6133US/TR?
JANTXV1N6133US/TR is rated for continuous operation from −65 °C to +175 °C per MIL-PRF-19500/211 Class V requirements. This extended range supports deployment in jet engine bays, satellite power systems, and desert-deployed radar platforms where ambient temperatures exceed commercial-grade limits. The JANTXV1N6133US/TR maintains specified clamping performance across this full range without derating.
Does JANTXV1N6133US/TR meet DO-160 Section 22 lightning surge requirements?
Yes, JANTXV1N6133US/TR meets DO-160 Section 22 Level 3 lightning-induced transient requirements when implemented with proper PCB layout and series impedance. Its 1.5 kW peak pulse power and 53.3 V clamping voltage at 38.3 A ensure protected circuits remain within safe operating area during waveform 3 (10/1000 μs) surges. The JANTXV1N6133US/TR is commonly deployed in certified avionics power supplies for this purpose.
Is JANTXV1N6133US/TR unidirectional or bidirectional?
JANTXV1N6133US/TR is a unidirectional TVS diode, designed for DC rail protection with polarity-sensitive placement. Its anode connects to the line and cathode to ground, enabling avalanche conduction only during positive transients. This configuration provides lower leakage and tighter clamping than bidirectional variants, making JANTXV1N6133US/TR ideal for regulated 28 V or 33 V aerospace power buses.
What is the leakage current specification for JANTXV1N6133US/TR at rated standoff voltage?
JANTXV1N6133US/TR exhibits ≤1 μA leakage current at 26.7 V, which is 80% of its 33 V standoff voltage. This ultra-low leakage prevents unnecessary power drain in battery-backed avionics systems and avoids measurement errors in precision analog monitoring circuits. The JANTXV1N6133US/TR maintains this spec across its full military temperature range.
How does the hermetic TO-204AD package of JANTXV1N6133US/TR improve reliability?
The hermetic TO-204AD (DO-201AD) metal-can package of JANTXV1N6133US/TR eliminates moisture ingress and prevents internal corrosion under thermal cycling and high-humidity conditions. This construction is mandatory for spaceflight and high-altitude aviation applications where outgassing or condensation could cause latent failure. The JANTXV1N6133US/TR's hermetic seal directly enables its MIL-PRF-19500/211 Class V qualification.
