Product details
Overview
MV1N8152US/TR from Microsemi is a voidless-hermetically-sealed unidirectional transient voltage suppressor (TVS) designed for high-reliability, high-frequency signal line protection. It delivers 150 W peak pulse power at 10/1000 µs, 9.0 V working standoff voltage (VWM), 15.6 V maximum clamping voltage (VC) at 9.62 A surge current, and ultra-low 4 pF capacitance - ideal for ESD-sensitive RF front-ends and MIL-STD-750-compliant aerospace interfaces.
For engineers reviewing the MV1N8152US/TR datasheet, MV1N8152US/TR pinout, MV1N8152US/TR application, or MV1N8152US/TR equivalent, key selection criteria include its Category 1 metallurgical bond, hermetic glass package, low-leakage standby current (≤5 µA), and IEC61000-4-2/4-4 compliance for mission-critical transient suppression in avionics and test equipment.
Technical Context
This TVS employs a unique series-connected rectifier diode in anti-parallel configuration with the avalanche junction to achieve 4 pF total capacitance - the lowest available for a 150 W-rated unidirectional TVS. Its hard-glass hermetic construction ensures zero voids and supports operation from –55 °C to +175 °C junction temperature.
The device operates as a unidirectional clamp with cathode-anode polarity, requiring correct orientation in series with protected lines. It achieves 15.6 V clamping at 9.62 A (10/1000 µs), with <0.075 %/°C breakdown voltage temperature coefficient and 300 V inverse blocking capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous reverse-bias voltage before leakage exceeds 5 µA; sets upper limit for protected line DC bias. |
| VC @ IPP | 15.6 V at 9.62 A - Clamped voltage during 10/1000 µs surge; determines worst-case overvoltage seen by downstream IC. |
| PPP | 150 W - Peak pulse power handling at 25 °C; defines transient energy absorption capacity per event. |
| CT | 4 pF - Total terminal capacitance at 0 V; enables use on >1 GHz RF paths without signal distortion. |
| TJ Range | –55 °C to +175 °C - Full military-grade operating range; supports engine bay, avionics bay, and downhole electronics. |
| ID @ VWM | ≤5 µA - Low standby leakage ensures minimal loading on high-impedance sensor or reference lines. |
| V(BR) Min | 10.4 V @ 1 mA - Guaranteed avalanche onset; ensures reliable triggering above system operating voltage. |
Pinout & Package

Applications
| Avionics Data Bus Protection | Radar RF Front-End Clamp |
|---|---|
Use Scenario: Protecting ARINC 429 or MIL-STD-1553B data lines from lightning-induced transients in flight control computers. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed in series with each differential pair, referenced to chassis ground. Use Value: 4 pF capacitance prevents signal integrity degradation at 1 MHz bus rates; 15.6 V clamping ensures FPGA I/O stays within absolute max rating. | Use Scenario: Shielding LNA input stages in X-band radar receivers from ESD and nearby EMP events. IC Role / Device Role / Timing Role: First-line transient suppressor mounted directly at SMA connector feedthrough before matching network. Use Value: 9.0 V VWM allows biasing of GaAs FETs while clamping surges below 16 V; hermetic seal prevents outgassing in vacuum-rated radomes. |
| Downhole Sensor Interface | High-Voltage Test Equipment Input |
Use Scenario: Safeguarding pressure/temperature sensor outputs in oil & gas logging tools exposed to 175 °C ambient and cable discharge events. IC Role / Device Role / Timing Role: Series-connected TVS on analog output line, with cathode tied to isolated instrument ground. Use Value: –55 °C to +175 °C operation eliminates derating; 300 V inverse blocking withstands induced common-mode spikes on long cables. | Use Scenario: Protecting calibrated input amplifiers in automated test equipment subjected to accidental 1 kV contact discharges. IC Role / Device Role / Timing Role: Primary clamp on BNC input path, placed before attenuator and gain stage. Use Value: 150 W PPP rating absorbs multiple 10/1000 µs pulses without parametric shift; 5 µA ID avoids DC offset errors in µV-level measurements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ9.0A | Surface-mount DO-214AB package; 1000 W PPP; 12.6 V VC @ 43.3 A; 100 pF CT. | Higher power but 25× higher capacitance - unsuitable for RF or high-speed digital lines. | Select only for board-space-constrained industrial controls where bandwidth <10 MHz. |
| 1N6375 | Axial-leaded, non-hermetic epoxy package; 150 W PPP; 12.5 V VC @ 12 A; 15 pF CT; commercial temp range only. | Lacks Category 1 bond, voidless seal, and radiation hardness - not qualified for aerospace or downhole use. | Acceptable for cost-sensitive telecom power supply rails where reliability requirements are lower. |
Compared with SMCJ9.0A and 1N6375, MV1N8152US/TR uniquely combines ultra-low capacitance, hermetic reliability, and extended temperature range - making it the only option for RF, avionics, and extreme-environment transient suppression where signal fidelity and zero-failure operation are mandatory.

FAQ
What is the maximum clamping voltage of MV1N8152US/TR under standard surge conditions?
The MV1N8152US/TR has a maximum clamping voltage (VC) of 15.6 V when subjected to a 10/1000 µs surge current of 9.62 A. This value is guaranteed across the full operating temperature range and reflects the worst-case voltage imposed on protected circuitry during transient events, ensuring compatibility with 3.3 V and 5 V logic I/O rails.
Is MV1N8152US/TR suitable for bidirectional transient protection?
No - MV1N8152US/TR is strictly unidirectional. For bidirectional protection, two MV1N8152US/TR devices must be connected in anti-parallel, as documented in Figure 5 of the datasheet. This configuration doubles the effective capacitance to 8 pF but maintains the same clamping performance in both polarities.
Does MV1N8152US/TR meet IEC61000-4-2 and IEC61000-4-4 standards?
Yes - MV1N8152US/TR provides ESD and EFT protection compliant with IEC61000-4-2 (±8 kV contact, ±15 kV air) and IEC61000-4-4 (4 kV burst), as confirmed in the Applications/Benefits section of the official datasheet. Its low capacitance and fast response ensure robust immunity without filtering high-frequency content.
What does the "MV" prefix indicate in MV1N8152US/TR?
The "MV" prefix in MV1N8152US/TR denotes JANTXV-level reliability qualification per MIL-PRF-19500, including enhanced screening, burn-in, and lot traceability. It signifies that the MV1N8152US/TR meets stringent military requirements for high-reliability applications such as avionics, space systems, and nuclear instrumentation.
Can MV1N8152US/TR be used in reflow soldering processes?
No - MV1N8152US/TR is an axial-leaded glass diode rated for wave or hand soldering only. Its maximum solder temperature is 260 °C for 10 seconds; reflow profiles exceed thermal limits and risk cracking the hermetic glass body or degrading internal bonds. Surface-mount alternatives like SMCJ9.0A should be used for reflow-compatible designs.
