Product details
Overview
JANS1N6152US/TR from Microsemi is a military-qualified, voidless hermetically sealed bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF package, rated for 1500 W peak pulse power (10/1000 µs), 20.6 V working standoff voltage (VWM), and 37.4 V clamping voltage (VC) at 40.1 A peak pulse current (IPP). It operates across –55 °C to +175 °C and is qualified to MIL-PRF-19500/516 JANS level for high-reliability aerospace and defense power rail protection.
For engineers reviewing the JANS1N6152US/TR datasheet, JANS1N6152US/TR pinout, JANS1N6152US/TR application, or JANS1N6152US/TR equivalent, key selection criteria include its bidirectional clamping behavior, Category 1 metallurgical bonds, hard-glass hermetic seal, 5.0 °C/W junction-to-end-cap thermal resistance, and compliance with IEC61000-4-2/4-4/4-5 for ESD, EFT, and lightning-induced surge immunity.
Technical Context
This device functions as a voltage-clamped transient protector on DC power lines and signal paths, leveraging avalanche breakdown in silicon to divert surge energy away from sensitive circuitry. Its bidirectional symmetry enables protection against both positive and negative polarity transients without polarity marking or orientation dependency.
It employs internal tungsten slugs and triple-layer passivation within a voidless hard-glass body, ensuring mechanical robustness and radiation hardness per MicroNote 050. Thermal performance is defined by RθJEC = 5.0 °C/W, enabling reliable operation up to 175 °C junction temperature under pulsed conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1500 W - sustains single high-energy surges without degradation |
| Working Standoff Voltage (VWM) | 20.6 V - maximum continuous DC voltage before leakage exceeds 5 µA |
| Clamping Voltage (VC @ IPP) | 37.4 V - limits voltage seen by protected circuit during 40.1 A transient |
| Breakdown Voltage (V(BR)) | 25.7 V @ 50 mA - onset of controlled avalanche conduction |
| Junction Temperature Range | –55 °C to +175 °C - supports operation in extreme environmental conditions |
| Thermal Resistance (RθJEC) | 5.0 °C/W - enables efficient heat transfer from junction to end cap under pulsed load |
| Temperature Coefficient of V(BR) | 0.09 %/°C - predictable V(BR) drift over temperature for stable clamping margin |
Pinout & Package
Package: SQ-MELF (Square-End-Cap Metal Electrode Leadless Face), 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 | Either end conducts during positive or negative transients - no orientation required during placement |
| End Cap (both ends) | Thermal and electrical interface | Primary heat dissipation path to PCB pad; also serves as low-inductance current return |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating rails without polarity constraints |
| Category 1 metallurgical bonds | Guarantees bond integrity under thermal cycling and mechanical shock per MIL-STD-750 |
| Voidless hermetic glass seal | Prevents moisture ingress and long-term parameter drift in humid or vacuum environments |
| Triple-layer passivation | Reduces surface leakage and enhances stability of V(BR) and ID under high-humidity bias stress |
| MIL-PRF-19500/516 JANS qualification | Validated reliability for mission-critical systems requiring zero-failure tolerance over full life cycle |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6152AUS | Commercial-grade version; same VWM, VC, IPP, but not MIL-qualified | Lacks JANS screening, derating, and radiation hardness validation | Select when cost-sensitive non-military applications require identical electrical specs without qualification overhead |
| JANTXV1N6152US | Same electrical specs; qualified to JANTXV level (lower screening rigor than JANS) | Approved for high-reliability programs where full JANS testing is not mandated | Choose for avionics subsystems needing MIL-PRF-19500/516 compliance but not space-grade assurance |
Compared with JANS1N6152US/TR, the 1N6152AUS offers identical clamping performance at lower cost but no radiation or extended-life validation, while JANTXV1N6152US provides intermediate reliability assurance-making JANS1N6152US/TR optimal for spaceflight, strategic systems, and nuclear instrumentation where zero-failure tolerance is mandatory.

FAQ
What is the clamping voltage of JANS1N6152US/TR at its rated peak pulse current?
The JANS1N6152US/TR has a maximum clamping voltage (VC) of 37.4 V when subjected to its rated peak pulse current (IPP) of 40.1 A under the standard 10/1000 µs waveform. This value is measured per MIL-STD-202 method 310 and guarantees that downstream circuitry remains within safe operating voltage limits during transient events.
Is JANS1N6152US/TR RoHS compliant?
No, JANS1N6152US/TR is not RoHS compliant. Per the manufacturer's documentation, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants (e.g., 1N6152AUS), not for JANS-level military-qualified parts, which retain tin/lead plating for enhanced solder joint reliability and thermal fatigue resistance.
How does the JANS qualification differ from JANTXV for JANS1N6152US/TR?
JANS1N6152US/TR undergoes more rigorous screening than JANTXV, including additional burn-in, extended temperature cycling, and radiation hardness verification per MIL-PRF-19500/516 Appendix A. JANTXV qualifies for high-reliability use but omits certain space-grade tests required for JANS, making JANS1N6152US/TR suitable for strategic and spaceborne systems where zero latent defects are mandated.
What is the thermal resistance specification for JANS1N6152US/TR, and how is it used in layout design?
JANS1N6152US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W. In PCB layout, this value guides pad sizing and copper pour area to ensure end-cap heat transfer meets derating curves-especially critical when operating near 175 °C junction limit under repeated surges. The SQ-MELF package requires symmetric, adequately sized SMD pads per the documented pad layout.
Can JANS1N6152US/TR be used in AC-coupled signal paths?
Yes, JANS1N6152US/TR is inherently bidirectional and suitable for AC-coupled signal paths such as MIL-STD-1553B, RS-422, or analog sensor interfaces. Its symmetrical V-I characteristics ensure equal clamping for both polarities, and its 20.6 V VWM allows use on signal lines referenced to ±15 V rails without leakage concerns at normal operating bias.
