Product details
Overview
JAN1N6148AUS/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 13.7 V working standoff voltage (VWM), 17.10 V minimum breakdown voltage (V(BR)) at 65 mA, and 25.1 V clamping voltage (VC) at 59.8 A peak pulse current (IPP) for 10/1000 µs waveform - deployed in avionics power rail protection.
For engineers reviewing the JAN1N6148AUS/TR datasheet, JAN1N6148AUS/TR pinout, JAN1N6148AUS/TR application, or JAN1N6148AUS/TR equivalent, key selection criteria include military-grade reliability (JAN qualification), bidirectional surge suppression capability, hermetic glass package robustness, and compatibility with high-reliability PCB assembly processes requiring 260 °C solder tolerance.
Technical Context
This TVS operates bidirectionally without polarity marking and uses Category 1 internal metallurgical bonds within a hard-glass, voidless hermetic enclosure - enabling stable performance across -55 °C to +175 °C junction temperature range. Its 1500 W peak pulse power rating (10/1000 µs) and 5.0 °C/W thermal resistance (junction-to-end cap) support high-energy transient absorption in constrained thermal environments.
The device exhibits low standby current (10 µA max at VWM = 13.7 V), a temperature coefficient of breakdown voltage of 0.085 %/°C, and ESD/EFT compliance per IEC61000-4-2 and IEC61000-4-4 - confirming suitability for mission-critical signal and power line protection where failure is not tolerable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.7 V - maximum continuous reverse voltage before conduction begins; sets operating margin for protected circuit. |
| V(BR) min | 17.10 V @ 65 mA - guaranteed breakdown onset; defines threshold for clamping activation. |
| VC @ IPP | 25.1 V @ 59.8 A - clamped voltage during 10/1000 µs surge; determines maximum stress on downstream components. |
| PPP | 1500 W - peak impulse power handling capacity; enables protection against lightning-induced surges per IEC61000-4-5. |
| ID @ VWM | 10 µA max - leakage current at rated standoff; ensures minimal power loss and noise injection in standby. |
| TJ Range | -55 °C to +175 °C - operational junction temperature span; supports deployment in extreme environmental conditions. |
| RθJEC | 5.0 °C/W - thermal resistance from junction to end cap; informs heatsinking requirements for sustained pulse duty cycles. |
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 operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge path | Either end serves as anode or cathode depending on transient polarity; no orientation required during placement. |
| End Cap (both ends) | Thermal and electrical interface | Provides mechanical mounting surface and primary heat dissipation path to PCB; requires direct thermal contact. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC or floating DC lines without polarity concerns or external diode pairing. |
| Category 1 metallurgical bonds | Ensures long-term bond integrity under thermal cycling and mechanical shock - critical for aerospace and defense deployments. |
| Voidless hermetic sealing | Prevents moisture ingress and internal corrosion over decades of service life in humid or high-vacuum environments. |
| JAN-level qualification | Validated to MIL-PRF-19500/516 screening including burn-in, temperature cycling, and lot acceptance testing. |
| Triple-layer passivation | Reduces surface leakage and enhances stability of V(BR) under high-humidity or contamination exposure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6148AUS | Higher screening level (JANTXV vs JAN); includes extended temperature testing and tighter parametric limits. | Required for programs mandating JANTXV-level reliability (e.g., DoD Class H). | Select when full MIL-PRF-19500/516 JANTXV qualification is contractually required. |
| 1N6148AUS | Commercial-grade version; lacks JAN-level screening, burn-in, and lot traceability. | Suitable only for non-military industrial applications with relaxed reliability requirements. | Choose for cost-sensitive prototyping or commercial subsystems where MIL-spec is not mandated. |
Compared with JANTXV1N6148AUS, the JAN1N6148AUS/TR offers verified JAN-level screening at lower cost and smaller test overhead, while 1N6148AUS provides identical electrical specs but no military qualification - making JAN1N6148AUS/TR the optimal balance of assured reliability and procurement efficiency for defense-tier designs.

FAQ
What is the clamping voltage of JAN1N6148AUS/TR under a 10/1000 µs surge?
The clamping voltage (VC) of JAN1N6148AUS/TR is 25.1 V at 59.8 A peak pulse current (IPP) for a 10/1000 µs waveform. This value is measured per standard test conditions defined in MIL-PRF-19500/516 and reflects the maximum voltage seen across the device during surge conduction - a critical parameter for ensuring downstream components remain within safe operating limits. The JAN1N6148AUS/TR maintains this clamping performance across its full qualified temperature range.
Is JAN1N6148AUS/TR RoHS compliant?
No, JAN1N6148AUS/TR is not RoHS compliant. Per the Microsemi datasheet T4-LDS-0278-1 Rev. 2, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants (e.g., 1N6148AUS), not for JAN-level qualified parts. The JAN1N6148AUS/TR uses traditional tin/lead plating on copper terminals and is intended for applications where military specification compliance takes precedence over RoHS restrictions.
What does the "A" suffix in JAN1N6148AUS/TR signify?
The "A" suffix in JAN1N6148AUS/TR indicates standard voltage tolerance: ±5% on V(BR), ±5% on VC, and ±5% on IPP - as opposed to non-A parts which have 5% higher VC, 5% lower minimum V(BR), and 5% lower IPP. This tighter tolerance band ensures predictable clamping behavior and consistent system-level protection margins, especially important in deterministic safety-critical designs using JAN1N6148AUS/TR.
Can JAN1N6148AUS/TR be used in place of JAN1N6147AUS or JAN1N6149AUS?
No, JAN1N6148AUS/TR is not a direct substitute for JAN1N6147AUS (VWM = 12.2 V) or JAN1N6149AUS (VWM = 15.2 V), as each part is uniquely specified for a distinct working standoff voltage. Substitution would risk premature conduction (if VWM too low) or insufficient protection (if VWM too high). System-level validation is required before interchanging any members of the 1N6138AUS–1N6173AUS family, including JAN1N6148AUS/TR.
What is the maximum steady-state power dissipation of JAN1N6148AUS/TR at 25 °C ambient?
The maximum steady-state power dissipation (PD) of JAN1N6148AUS/TR is 3.0 W at TA = 25 °C, per the datasheet's "Off-State Power @ TA = 25 °C" rating. This applies only when the device is not conducting - i.e., when reverse voltage remains below VWM (13.7 V). Derating is required above 25 °C ambient, following the curve in Figure 5; at 70 °C ambient, PD drops to approximately 1.8 W for free-air mounting.
