Overview
JAN1N6173AUS/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JAN level, with 152 V working standoff voltage (VWM), 273 V clamping voltage (VC) at 5.5 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform - deployed in aerospace power bus protection and avionics interface circuits.
For engineers reviewing the JAN1N6173AUS/TR datasheet, JAN1N6173AUS/TR pinout, JAN1N6173AUS/TR application, or JAN1N6173AUS/TR equivalent, this page delivers verified military-grade TVS parameters, package dimensions, clamping behavior under surge, thermal derating curves, and direct alternatives compliant with IEC61000-4-2/4-4/4-5 and MIL-STD-750.
Technical Context
The JAN1N6173AUS/TR uses hard-glass hermetic construction with internal Category 1 metallurgical bonds, enabling operation from −55 °C to +175 °C and radiation-hardened performance per MicroNote 050. Its bidirectional architecture provides symmetrical clamping without polarity marking.
It delivers 1500 W peak pulse power (10/1000 µs), with thermal resistance junction-to-end cap of 5.0 °C/W and linear derating above 150 °C end-cap temperature. Standby current is ≤5 µA at 152 V VWM, and breakdown occurs at minimum 190 V @ 5 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 152 V - maximum continuous reverse voltage before conduction; sets operating margin for 120–150 V DC power rails. |
| V(BR) min | 190 V @ 5 mA - guaranteed avalanche onset; ensures predictable turn-on above nominal system voltage. |
| VC @ IPP | 273 V @ 5.5 A - clamped voltage during 10/1000 µs surge; limits downstream stress to <275 V. |
| PPP | 1500 W - peak transient energy handling capacity; supports lightning-induced surges per IEC61000-4-5 Level 3. |
| ID @ VWM | ≤5 µA - ultra-low leakage at rated standoff; avoids parasitic loading in high-impedance sensing paths. |
| TJ/TSTG | −55 °C to +175 °C - extended military temperature range; validated for engine bay and space-qualified enclosures. |
| RθJEC | 5.0 °C/W - low thermal resistance to end cap; enables direct heatsinking via PCB copper pour or chassis contact. |
Pinout & Package
Package: SQ-MELF (C-package variant), hermetically sealed voidless hard glass with tungsten slugs; terminals are tin/lead plated copper; no polarity marking due to bidirectional symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Surge current path | Both ends function identically as symmetrical avalanche terminals; no orientation required during placement. |
| End caps | Thermal & electrical interface | Direct thermal conduction path to PCB or chassis; used for both current return and heat dissipation. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6173AUS (commercial grade) | No JAN reliability screening; same VWM, VC, and PPP specs but not MIL-PRF-19500/516 qualified. | Limited to non-mission-critical industrial or test equipment where radiation hardness and extended temp validation are unnecessary. | Select when cost sensitivity outweighs qualification requirements and full lifecycle traceability is not mandated. |
| JANTXV1N6173AUS | Higher reliability screening (JANTXV level), tighter parametric lot testing, and extended burn-in vs. JAN level. | Required for Class H/V space programs and DoD platforms demanding zero latent defects and full DSCC traceability. | Choose when system-level FMEA mandates enhanced defect elimination beyond JAN baseline, especially for launch-critical subsystems. |
Compared with JAN1N6173AUS/TR, the commercial 1N6173AUS offers identical electrical performance at lower cost but lacks military qualification evidence, while JANTXV1N6173AUS adds screening rigor for ultra-high-assurance deployments - enabling tiered selection based on program assurance level, not just clamping specs.

FAQ
What is the clamping voltage of JAN1N6173AUS/TR and how is it measured?
The clamping voltage (VC) of JAN1N6173AUS/TR is 273 V, measured at 5.5 A peak pulse current (IPP) using a standardized 10/1000 µs double-exponential surge waveform. This value reflects the maximum voltage seen across the device during a defined transient event and is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0278-1 datasheet. The JAN1N6173AUS/TR maintains this clamping performance across its full operating temperature range.
Is JAN1N6173AUS/TR RoHS compliant?
No, JAN1N6173AUS/TR is not RoHS compliant. Per the datasheet nomenclature and packaging section, RoHS-compliant matte-tin plating is available only on commercial-grade versions (e.g., 1N6173AUS without JAN prefix). The JAN1N6173AUS/TR uses standard tin/lead plating to meet MIL-PRF-19500/516 process and reliability requirements.
What does the "A" suffix in JAN1N6173AUS/TR indicate?
The "A" suffix in JAN1N6173AUS/TR denotes standard voltage tolerance: minimum breakdown voltage (V(BR)) is 190 V, clamping voltage (VC) is 273 V, and peak pulse current (IPP) is 5.5 A. Non-A versions have 5% higher VC, 5% lower minimum V(BR), and 5% lower IPP - making the "A" version the tighter, more predictable variant for precision protection design.
Can JAN1N6173AUS/TR be used in place of axial-leaded 1N6173 parts?
No - JAN1N6173AUS/TR is a surface-mount SQ-MELF (C-package) device, while axial-leaded 1N6173 variants use through-hole TO-204AA (DO-4) packaging. They share identical electrical specifications but differ in mechanical form, thermal path, and PCB assembly method. Substitution requires layout redesign and revalidation of thermal and surge-current paths.
What is the maximum steady-state power dissipation for JAN1N6173AUS/TR at 25 °C ambient?
The maximum steady-state power dissipation for JAN1N6173AUS/TR is 3.0 W at TA = 25 °C, as specified in the Maximum Ratings table. This rating assumes controlled thermal resistance from mounting point to ambient; derating begins linearly above 25 °C per Figure 4, reaching zero at 150 °C ambient. For reliable operation, ensure adequate copper area or heatsinking per the pad layout on page 7.
