Product details
Overview
MV1N8177US/TR from Microsemi is a voidless-hermetically-sealed unidirectional transient voltage suppressor (TVS) with 4 pF capacitance, 114 V working standoff voltage (VWM), and 150 W peak pulse power at 10/1000 µs. It features internal Category 1 metallurgical bonds, triple-layer passivation, and RoHS-compliant matte tin plating for high-reliability aerospace and defense transient protection.
For engineers reviewing the MV1N8177US/TR datasheet, MV1N8177US/TR pinout, MV1N8177US/TR application, or MV1N8177US/TR equivalent, key selection criteria include low-capacitance ESD/EFT immunity per IEC61000-4-2/4-4, clamping voltage of 168 V at 300 A surge, and hermetic glass package suitability for radiation-hardened environments.
Technical Context
This TVS uses a unique series-connected rectifier diode in anti-parallel configuration to achieve ultra-low 4 pF capacitance while maintaining unidirectional operation. Its hard-glass hermetic construction enables operation from –55 °C to +175 °C junction temperature with 150 W peak pulse power rating.
The device delivers 114 V working standoff voltage (VWM), 168 V clamping voltage (VC) at 300 A IPP, and <0.5 µA standby current at rated VWM. Its 0.107 %/°C breakdown voltage temperature coefficient ensures stable overvoltage protection across wide thermal ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 114 V - Maximum continuous reverse-biased operating voltage before conduction begins. |
| VC @ IPP=300 A | 168 V - Clamped voltage during 10/1000 µs surge, limiting downstream circuit stress. |
| Capacitance | 4 pF - Enables use in >1 GHz RF front-ends and high-speed data lines without signal distortion. |
| PPP | 150 W - Peak transient energy absorption capability under standardized 10/1000 µs waveform. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ110A | Surface-mount DO-214AB package; 110 V VWM; 170 V VC @ 300 A; 6.5 pF capacitance. | Higher capacitance limits use in >500 MHz circuits; lacks hermetic seal and radiation hardness. | Preferred for cost-sensitive commercial designs requiring SMT assembly and moderate reliability. |
| 1N8177US/TR (MV version) | Same electrical specs but with JANTXV-grade reliability screening and enhanced test coverage per MIL-PRF-19500. | Qualified for spaceflight and military platforms requiring full lot traceability and extended temperature validation. | Select when compliance with MIL-PRF-19500 Class V or NASA EEE-INST-002 is mandatory. |
Compared with SMCJ110A and the commercial 1N8177US/TR, MV1N8177US/TR provides lower capacitance, hermetic reliability, and radiation tolerance-critical for aerospace and defense systems where failure modes must be eliminated-not just mitigated.

FAQ
What is the clamping voltage of MV1N8177US/TR at its rated peak impulse current?
The MV1N8177US/TR has a maximum clamping voltage (VC) of 168 V when subjected to a 300 A peak impulse current (IPP) under the standard 10/1000 µs waveform. This value is measured at 25 °C and ensures protected circuits remain below their absolute maximum voltage ratings during surge events. The MV1N8177US/TR maintains this clamping performance across its full operating temperature range due to its low temperature coefficient.
Is MV1N8177US/TR suitable for bidirectional transient protection?
No, MV1N8177US/TR is a unidirectional TVS. For bidirectional protection, two MV1N8177US/TR devices must be connected in anti-parallel configuration, as documented in Figure 5 of the datasheet. This arrangement doubles the effective capacitance to 8 pF but retains the same VWM and clamping characteristics in both polarities.
Does MV1N8177US/TR meet IEC61000-4-2 and IEC61000-4-4 standards?
Yes, MV1N8177US/TR provides ESD protection per IEC61000-4-2 and EFT protection per IEC61000-4-4, as confirmed in the Applications/Benefits section of the official datasheet. Its 4 pF capacitance and fast response time enable effective suppression of contact and air-discharge events up to ±15 kV, making it suitable for high-integrity interface protection.
What does the "MV" prefix indicate in MV1N8177US/TR?
The "MV" prefix in MV1N8177US/TR denotes JANTXV-level reliability qualification per MIL-PRF-19500, including extended temperature testing, lot traceability, and enhanced screening for space and defense applications. It distinguishes this variant from commercial (blank), JAN (MQ), or JANTX (MX) versions of the same 1N8177US base part.
Can MV1N8177US/TR be used in radiation-intensive environments?
Yes, MV1N8177US/TR is inherently radiation-hardened as described in Microsemi MicroNote 050. Its hermetic glass package, Category 1 metallurgical bonds, and silicon process design provide tolerance to total ionizing dose (TID) and single-event effects (SEE), enabling deployment in satellite, nuclear, and high-altitude avionics systems without derating.
