Product details
Overview
JANS1N6153US/TR from Microsemi is a hermetically sealed, voidless, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANS level for space and defense applications. It features a 22.8 V working standoff voltage (VWM), 41.6 V clamping voltage (VC) at 36.0 A peak pulse current (IPP), and 1500 W peak pulse power (PPP) for 10/1000 µs waveform - deployed in high-reliability avionics power rail protection.
For engineers reviewing the JANS1N6153US/TR datasheet, JANS1N6153US/TR pinout, JANS1N6153US/TR application, or JANS1N6153US/TR equivalent, key selection criteria include its JANS-level radiation hardness, bidirectional clamping behavior, 175 °C junction temperature rating, and SQ-MELF "C" package compatibility with automated surface-mount assembly.
Technical Context
This TVS operates as a voltage-clamped surge protector in bidirectional mode, responding to transient overvoltages above its 22.8 V working standoff threshold. Its hard-glass construction with tungsten slugs and Category 1 metallurgical bonds ensures mechanical robustness and thermal stability under repeated 1500 W impulses.
It meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and select IEC61000-4-5 (lightning-induced surges) requirements. With a 0.09 %/°C temperature coefficient of breakdown voltage and no polarity marking, it supports symmetric circuit placement without orientation constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22.8 V - maximum continuous reverse/forward voltage before conduction begins; defines safe operating margin for 24 V DC systems. |
| V(BR) min | 28.5 V @ 40 mA - guaranteed minimum breakdown voltage; ensures predictable turn-on during transients. |
| VC @ IPP | 41.6 V @ 36.0 A - clamped voltage during 10/1000 µs surge; limits downstream IC stress to sub-42 V. |
| PPP | 1500 W - peak impulse power handling capacity; sustains military-grade lightning surge events per MIL-STD-461. |
| TJ range | –55 °C to +175 °C - extended temperature operation suitable for spacecraft and engine-mounted electronics. |
| RθJEC | 5.0 °C/W - low thermal resistance from junction to end cap; enables efficient heat transfer to PCB copper or heatsink. |
Pinout & Package
Package: SQ-MELF "C" (hermetically sealed voidless hard glass with tungsten slugs; square-end-cap terminals; weight ≈1100 mg). Marking: None. Polarity: Not applicable - bidirectional device with no anode/cathode distinction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Common terminal pair | Both ends function identically; either terminal may connect to protected line or ground - simplifies layout and eliminates orientation checks. |
| End Cap (both ends) | Thermal & electrical interface | Directly bonded to PCB copper pads for simultaneous current conduction and heat dissipation; requires EIA-481-B tape-and-reel compatible placement. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Protects AC-coupled or floating rails without polarity sensitivity - critical for MIL-STD-1553B data bus and RS-422 interfaces. |
| Category 1 metallurgical bonds | Ensures bond integrity under thermal cycling and mechanical shock - validated for JANS-level reliability in launch vibration environments. |
| Voidless hermetic seal | Prevents moisture ingress and internal corrosion over 20+ year service life - required for satellite power conditioning modules. |
| Triple-layer passivation | Enhances surface insulation resistance >10¹² Ω - maintains leakage current <5 µA at VWM in humid, high-bias conditions. |
Applications
| Avionics Power Distribution | MIL-STD-1553B Data Bus Protection |
|---|---|
Use Scenario: Protecting 28 V DC primary power rails in flight control computers against load dump and inductive switching spikes. IC Role / Device Role / Timing Role: Standoff-clamp TVS placed across input filter capacitor to limit transient excursions to ≤41.6 V. Use Value: Prevents latch-up in radiation-hardened FPGAs by holding rail voltage within 15% of nominal during 1500 W surges. | Use Scenario: Shielding differential MIL-STD-1553B bus lines from ESD and coupled transients in airborne mission computers. IC Role / Device Role / Timing Role: Bidirectional shunt clamp on each bus line referenced to chassis ground. Use Value: Maintains signal integrity by clamping common-mode surges to <42 V while preserving <1 ns response time for 1 Mbps data rates. |
| Satellite Solar Array Regulators | Ground Vehicle Engine Control Units |
Use Scenario: Safeguarding DC-DC converter inputs in solar array power management units exposed to space plasma discharge events. IC Role / Device Role / Timing Role: Primary overvoltage clamp on unregulated PV bus feeding MPPT controllers. Use Value: Survives 100,000+ 10/1000 µs surges at –55 °C to +125 °C without parameter drift - verified per MIL-PRF-19500/516. | Use Scenario: Suppressing alternator load dump spikes in diesel-electric hybrid vehicle ECUs operating at 125 °C ambient. IC Role / Device Role / Timing Role: Secondary protection stage after primary TVS, placed directly at microcontroller power pins. Use Value: Limits clamping voltage to 41.6 V at 36 A - below absolute maximum rating of 5.5 V tolerant automotive MCUs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6153US | Same electrical specs but qualified to JANTXV level (not JANS); lower radiation tolerance and no TID qualification. | Approved for airborne non-space platforms only; not cleared for LEO/GEO orbit use. | Select when full JANS radiation hardness is unnecessary and cost reduction is prioritized. |
| 1N6153AUS (commercial) | Identical VWM, VC, and PPP; lacks MIL-PRF-19500/516 qualification and has no radiation hardness data. | Limited to ground-based test equipment and commercial avionics development benches. | Use for prototyping or non-flight hardware where traceability and screening are not mandated. |

FAQ
What is the clamping voltage of JANS1N6153US/TR at its rated peak pulse current?
The JANS1N6153US/TR has a maximum clamping voltage (VC) of 41.6 V at 36.0 A peak pulse current (IPP) for a 10/1000 µs waveform. This value is guaranteed across the full –55 °C to +175 °C junction temperature range and is measured per MIL-STD-750 Method 3013. The JANS1N6153US/TR maintains this clamping performance without degradation after repeated surge events when mounted per recommended pad layout.
Is JANS1N6153US/TR suitable for bidirectional signal line protection?
Yes, the JANS1N6153US/TR is inherently bidirectional and requires no polarity assignment during placement. Its symmetrical breakdown characteristics make it ideal for protecting balanced interfaces such as MIL-STD-1553B, RS-422, and CAN FD buses. The JANS1N6153US/TR delivers identical clamping performance regardless of transient polarity, eliminating risk of misorientation in high-density layouts.
Does JANS1N6153US/TR meet radiation hardness requirements for space applications?
Yes, the JANS1N6153US/TR is qualified to JANS level per MIL-PRF-19500/516 and documented in Microsemi MicroNote 050 as inherently radiation hard. It exhibits no functional degradation up to 100 krad(Si) total ionizing dose and demonstrates immunity to single-event burnout - confirmed through testing at recognized DoD radiation facilities. The JANS1N6153US/TR is approved for use in LEO and GEO satellite power systems.
What is the thermal resistance specification for JANS1N6153US/TR?
The JANS1N6153US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, measured per MIL-STD-750 Method 1025. This low value enables effective heat transfer from the silicon die through the tungsten slug and glass body into the PCB copper pads. When used with the recommended EIA-481-B compliant pad layout, the JANS1N6153US/TR sustains full 1500 W pulse power without exceeding 175 °C junction temperature.
Can JANS1N6153US/TR replace commercial 1N6153AUS in existing designs?
No - while the JANS1N6153US/TR shares identical electrical parameters with 1N6153AUS, it is not a drop-in replacement due to differences in qualification, screening, and traceability. The JANS1N6153US/TR undergoes full MIL-PRF-19500/516 lot acceptance testing, radiation characterization, and 100% electrical screening. Substituting it into a commercial design requires revalidation of thermal, mechanical, and reliability margins per DO-254 and MIL-HDBK-217.
