Product details
Overview
JANS1N6138US from Semtech is a high-reliability, 1500 W bipolar transient voltage suppression (TVS) diode in surface-mount package, rated for 5.2 V reverse standoff voltage (VR), 500 µA maximum leakage current (ID), and operating across –65°C to +175°C. It delivers robust ESD and surge protection for power rails and signal lines in radiation-hardened aerospace systems including satellite power converters and launch vehicle avionics.
For engineers reviewing the JANS1N6138US datasheet, pinout, applications, or equivalent options, this part is selected for mission-critical overvoltage clamping where MIL-PRF-19500/516 compliance, wafer-level traceability, and Category I eutectic bond construction are mandatory.
Technical Context
This bipolar TVS diode features symmetrical clamping behavior with identical breakdown and clamping characteristics in both polarities, enabling bidirectional surge suppression without polarity constraints. Its die-glass sleeve passivation and OFHC copper terminations with solder plate finish ensure mechanical integrity and thermal reliability under extreme thermal cycling and vibration.
Designed per MIL-PRF-19500/516, the JANS1N6138US undergoes rigorous up-screening including single diffusion lot control, laser serialization, and fallout summary reporting-critical for space-grade component qualification and lot homogeneity assurance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W (10/1000 µs waveform; enables protection against lightning-induced transients in spacecraft bus systems) |
| Reverse Standoff Voltage (VR) | 5.2 V (maximum DC or continuous AC voltage before significant leakage; sets minimum system operating margin) |
| Maximum Leakage Current (ID) | 500 µA at VR (low quiescent loss critical for low-power satellite subsystems) |
| Clamping Voltage (VC) | 9.2 V at 100 A peak pulse (defines worst-case voltage seen by protected IC during surge event) |
| Operating Temperature Range | –65°C to +175°C (supports operation in deep-space thermal environments and rocket motor proximity) |
| Qualification Standard | MIL-PRF-19500/516 (certifies compliance with military-grade TVS device requirements for space applications) |
Pinout & Package
The JANS1N6138US is supplied in a surface-mount package conforming to Semtech's standard axial-to-SMT transition footprint, with two terminals: Cathode and Anode. The package uses OFHC copper leads with solder plate finish and features a die-glass sleeve for enhanced mechanical strength.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal for forward conduction; referenced to ground in unidirectional clamp configurations | Accepts surge current in negative polarity events; forms symmetrical path with cathode in bipolar operation |
| Cathode | Reference terminal for voltage clamping; typically connected to protected rail or signal line | Serves as clamping reference point; determines VR threshold and defines VC under positive transient conditions |
Key Features
| Feature | Design Value |
|---|---|
| Bipolar transient suppression | Identical clamping performance in both directions eliminates need for polarity-aware layout or external diode pairing |
| Category I eutectic bond construction | Ensures interfacial reliability under >100,000 thermal cycles and high-G launch vibration profiles |
| Wafer-level traceability & laser serialization | Enables full pedigree tracking from silicon wafer to individual device-required for NASA and DoD mission audits |
| MIL-PRF-19500/516 qualification | Validates compliance with screening, environmental, and electrical test requirements for space-grade TVS devices |
| Die-glass sleeve passivation | Provides mechanical reinforcement and moisture resistance exceeding MIL-STD-750 Method 1072 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bipolar TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N6138 | Axial-lead variant with identical electrical specs (VR = 5.2 V, 1500 W), but larger footprint and lead-forming requirements | Suitable for through-hole PCBs or hybrid assemblies; not compatible with SMT reflow processes | Select JANS1N6138US for automated SMT production; choose JANS1N6138 only when axial mounting or legacy board compatibility is required |
| JANS1N6138AUS | Same package and VR rating, but tighter ID specification (300 µA max vs. 500 µA) and enhanced screening per MIL-PRF-19500/516 Appendix A | Preferred for Class S (spacecraft) missions requiring lowest possible leakage in ultra-low-power dormant modes | JANS1N6138AUS offers higher reliability assurance; JANS1N6138US balances cost and performance for Class B/C missions |
Compared with JANS1N6138 and JANS1N6138AUS, the JANS1N6138US provides optimal trade-off between manufacturability (SMT-compatible), leakage tolerance (500 µA), and qualification depth-making it the default choice for high-volume space electronics where reflow assembly and MIL-PRF-19500/516 compliance are both required.

FAQ
What is the clamping voltage of JANS1N6138US at 100 A peak current?
The JANS1N6138US has a maximum clamping voltage (VC) of 9.2 V at 100 A peak pulse current (10/1000 µs waveform). This value is measured under standardized surge conditions and defines the upper voltage limit imposed on protected circuits during transient events. The JANS1N6138US maintains this clamping performance symmetrically in both polarities due to its bipolar construction.
Is JANS1N6138US qualified to MIL-PRF-19500/516?
Yes, JANS1N6138US is fully qualified to MIL-PRF-19500/516 for TVS devices. This includes compliance with electrical, environmental, and screening requirements such as temperature cycling, mechanical shock, vibration, and hermeticity testing. Qualification documentation-including fallout summaries and lot traceability-is provided with each shipment of JANS1N6138US.
What is the difference between JANS1N6138US and JANS1N6138AUS?
JANS1N6138AUS is a screened variant of JANS1N6138US with tighter leakage current specification (300 µA max vs. 500 µA) and additional Appendix A screening per MIL-PRF-19500/516. Both share identical VR (5.2 V), VC (9.2 V), and package dimensions. JANS1N6138US is appropriate for Class B/C space missions; JANS1N6138AUS targets Class S (highest reliability) applications.
Does JANS1N6138US support operation at –65°C?
Yes, JANS1N6138US is characterized and qualified for continuous operation from –65°C to +175°C. Its Category I eutectic bond, die-glass sleeve passivation, and OFHC copper terminations ensure mechanical and electrical stability across this full military temperature range-validated per MIL-STD-750 and MIL-STD-202 test methods.
Can JANS1N6138US be used in place of JANS1N6138 in new designs?
JANS1N6138US is the surface-mount counterpart to the axial-lead JANS1N6138 and shares identical electrical specifications (VR = 5.2 V, 1500 W, VC = 9.2 V). However, they are not mechanically interchangeable: JANS1N6138US requires SMT reflow assembly and occupies a different PCB footprint. Use JANS1N6138US only in designs with compatible land patterns and reflow profiles.
