Product details
Overview
JAN1N5652A from Microchip Technology is a hermetically sealed, unidirectional transient voltage suppressor (TVS) diode in DO-13 metal package, designed for high-reliability aerospace and military systems. It features 50.2 V rated standoff voltage (VWM), 55.8–58.9 V breakdown voltage (V(BR)) at 1 mA, 85.0 V maximum clamping voltage (VC) at 17.7 A peak pulse current (IPP), and 1500 W peak pulse power rating at 10/1000 µs waveform - used to protect avionics power rails against secondary lightning surges per IEC61000-4-5.
For engineers reviewing the JAN1N5652A datasheet, JAN1N5652A pinout, JAN1N5652A application, or JAN1N5652A equivalent, this part is selected for ruggedized through-hole surge protection where radiation hardness, hermetic sealing, and MIL-PRF-19500/500 JANTXV qualification are mandatory - especially in airborne electrical subsystems with operating temperatures from –55°C to +175°C.
Technical Context
The JAN1N5652A operates as a unidirectional avalanche diode, entering controlled breakdown when transient voltage exceeds its V(BR) threshold, clamping downstream circuitry to ≤85.0 V within <100 ps. Its DO-13 metal-glass package provides low thermal resistance (50°C/W junction-to-lead) and inherent radiation hardness per MicroNote 050.
It is rated for 1500 W non-repetitive peak pulse power at 10/1000 µs, with 5 µA maximum standby leakage at 50.2 V VWM and 0.104 %/°C temperature coefficient of V(BR). Polarity is marked by cathode connection to case, enabling straightforward grounding in series-connected protection schemes.

Applications
| Aerospace Power Distribution | Avionics Sensor Interface |
|---|---|
Use Scenario: Protection of 28 V DC main bus feeders in commercial and military aircraft against load dump and induced lightning coupling. IC Role / Device Role / Timing Role: Unidirectional TVS placed between bus and chassis ground to clamp transients exceeding 50.2 V while remaining non-conductive during nominal operation. Use Value: Limits bus overvoltage to ≤85.0 V during 17.7 A surges, preventing latch-up or gate oxide damage in upstream DC-DC controllers and solid-state power controllers. |
Use Scenario: Shielding ARINC 429 receiver inputs and discrete discretes (e.g., flap position sensors) from radiated RF and switching noise in wing-mounted electronics. IC Role / Device Role / Timing Role: Low-leakage (5 µA @ 50.2 V) TVS mounted directly at connector entry to minimize stub inductance and preserve signal integrity. Use Value: Sub-100 ps response ensures clamping occurs before 10 ns edge rates of fast-switching actuators induce destructive voltages on CMOS input stages. |
| Military Vehicle ECUs | Spacecraft Payload Power |
Use Scenario: Surge protection for 24 V CAN and MIL-STD-1553B data lines in tracked vehicle electronic control units exposed to EMP and ignition transients. IC Role / Device Role / Timing Role: Cathode-to-chassis mounting enables low-inductance path to vehicle ground, critical for suppressing >1 kV transients with minimal overshoot. Use Value: Hermetic DO-13 construction maintains V(BR) stability after 1000+ thermal cycles (-55°C/+125°C), ensuring long-term reliability in desert or arctic deployments. |
Use Scenario: Input protection for DC-DC converters powering star tracker imagers and reaction wheel drivers aboard LEO satellites. IC Role / Device Role / Timing Role: Radiation-hardened TVS deployed at primary power entry to absorb single-event transients induced by trapped protons in South Atlantic Anomaly passes. Use Value: Inherent TID resilience per MicroNote 050 eliminates need for additional shielding or derating, reducing SWaP-C in constrained payload bays. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5652A | Commercial-grade version; same VWM (50.2 V), VC (85.0 V), and DO-13 package but lacks MIL-PRF-19500/500 screening. | Approved for industrial or non-flight-critical avionics; not qualified for JANTXV-level environmental or life testing. | Select when radiation hardness and extended temperature validation are not required, and cost sensitivity outweighs qualification needs. |
| JANTXV1N5652UR | Same electrical specs but in DO-204AC (DO-15) package; slightly higher thermal resistance (60°C/W vs. 50°C/W) and plastic encapsulation. | Lacks hermetic seal and inherent radiation tolerance; unsuitable for vacuum or high-humidity aerospace deployments. | Choose only for space-constrained PCB layouts where DO-13 footprint is prohibitive and radiation exposure is negligible. |
Compared with JAN1N5652A, the 1N5652A omits military screening but retains identical clamping performance, while JANTXV1N5652UR trades hermeticity and radiation hardness for smaller footprint - making JAN1N5652A the sole choice for mission-critical, radiation-exposed, high-temperature avionics surge protection.

FAQ
What is the standoff voltage (VWM) of the JAN1N5652A and how does it relate to system design?
The JAN1N5652A has a rated standoff voltage (VWM) of 50.2 V, meaning it remains non-conductive up to this reverse voltage under normal operation. This value must be ≥ the maximum continuous DC or peak AC voltage of the protected line - for example, it is correctly applied on a 28 V aircraft bus with margin for ripple and transients. Exceeding VWM risks premature leakage or thermal runaway, so proper derating per Figure 3 in the datasheet is essential for sustained reliability in JAN1N5652A deployments.
Does the JAN1N5652A meet IEC61000-4-5 for lightning surge immunity, and at what class level?
Yes, the JAN1N5652A supports IEC61000-4-5 secondary lightning protection: it qualifies for Class 3 with 42 Ω source impedance, Class 2 with 12 Ω, and Class 2 with 2 Ω source impedance per the manufacturer's classification table. Its 1500 W peak pulse power and 85.0 V clamping voltage at 17.7 A ensure compliant voltage limiting across these test configurations - a key reason JAN1N5652A is specified in avionics lightning protection schematics where coordinated suppression with upstream filters is required.
How is the cathode terminal configured on the JAN1N5652A, and why does it matter for PCB layout?
The cathode of the JAN1N5652A is internally connected to the metal case and designated as Lead 1; polarity is marked by a diode symbol on the DO-13 body. This configuration mandates direct soldering of the case to the system ground plane to minimize inductance in the clamping path. Failure to do so - for instance, floating the case or routing cathode via a long trace - increases overshoot during fast transients and degrades the <100 ps response advantage of JAN1N5652A, risking damage to downstream components.
Is the JAN1N5652A radiation hardened, and what documentation confirms this?
Yes, the JAN1N5652A is inherently radiation hard per Microsemi MicroNote 050, a publicly archived application note validating total ionizing dose (TID) resilience without additional shielding or process modifications. This property stems from its DO-13 metal-glass construction and silicon processing, and is retained across all JAN/JANTX/JANTXV variants. Engineers specifying JAN1N5652A for satellite or high-altitude platforms rely on this documented hardness - not just qualification status - to justify reduced margins in radiation-tolerant power architectures.
What is the thermal resistance of the JAN1N5652A, and how does it affect surge duty cycle?
The JAN1N5652A has a junction-to-lead thermal resistance of 50°C/W when measured at 0.375 inches (10 mm) from the case body. This low value enables rapid heat dissipation during single 10/1000 µs pulses, supporting the full 1500 W rating. However, for repetitive surges, thermal accumulation requires strict adherence to the 0.01% duty cycle limit stated in the datasheet - exceeding this without active cooling risks junction overheating and parametric shift. Designers must reference Figure 4 derating curves when implementing JAN1N5652A in systems with frequent transient events.
