Product details
Overview
JANTXV1N6470US/TR from Microsemi is a military-qualified unidirectional transient voltage suppressor (TVS) diode in hermetically sealed voidless glass package (Package G/D-5C), with 6.0 V working peak standoff voltage (VWM), 11.0 V maximum clamping voltage at 775 A peak pulse current (10/1000 µs), and 1500 W peak pulse power rating. It serves as primary overvoltage protection for MIL-STD-1275 automotive power buses and avionics DC input stages.
For engineers reviewing the JANTXV1N6470US/TR datasheet, JANTXV1N6470US/TR pinout, JANTXV1N6470US/TR application, or JANTXV1N6470US/TR equivalent, key selection criteria include standoff voltage tolerance, clamping performance under 10/1000 µs surge, hermetic reliability for extended temperature operation (-55°C to +175°C), and compliance with MIL-PRF-19500/552 Category I metallurgical bonding requirements.
Technical Context
This unidirectional TVS operates in avalanche breakdown mode above its minimum breakdown voltage of 6.5 V (at 50 mA), maintaining a stable 6.0 V working peak standoff voltage up to 1000 µA leakage. Its hard-glass construction with tungsten slugs and copper end caps enables thermal resistance of 20.0 °C/W junction-to-end-cap and supports 130 A forward surge current (8.33 ms half-sine).
The device meets IEC61000-4-2 ESD (±15 kV air), IEC61000-4-4 EFT (40 A), and select IEC61000-4-5 lightning surge levels, with inherent radiation hardness per MicroNote 050. Its cathode-band polarity and square-end-cap terminals are optimized for surface-mount reflow and mechanical stability on high-reliability PCBs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6471US | Higher VWM (12 V), lower IPP (374 A), same 1500 W PPP | Suitable for 12 V systems; less effective for 24–28 V bus protection | Select when protecting 12 V logic rails where tighter VWM margin is required |
| SMCJ6.0A | Plastic SMC package, 6.0 V VWM, 11.2 V VC @ 103 A (10/1000 µs), 1500 W PPP | Limited to commercial temp range (-65°C to +150°C); not MIL-qualified | Use only in non-military industrial designs where hermeticity and radiation hardness are not required |
Compared with JANTXV1N6470US/TR, JANTXV1N6471US shifts protection threshold upward for 12 V systems but sacrifices surge current capacity, while SMCJ6.0A offers cost-effective commercial-grade replacement without military screening, hermetic sealing, or extended temperature capability.

FAQ
What is the maximum clamping voltage of JANTXV1N6470US/TR under standard test conditions?
The JANTXV1N6470US/TR has a maximum clamping voltage (VC) of 11.0 V when subjected to a 10/1000 µs surge waveform at 775 A peak pulse current. This value is measured per MIL-STD-1275B and IEC61000-4-5 Annex C test methods and reflects worst-case voltage seen by downstream circuitry during transient events. The JANTXV1N6470US/TR maintains this clamping performance across its full -55°C to +175°C operating range.
Is JANTXV1N6470US/TR compliant with MIL-PRF-19500/552?
Yes, JANTXV1N6470US/TR is fully qualified to MIL-PRF-19500/552 as a Category I unidirectional TVS diode. It features internal metallurgical bonds validated per Test Method 2019, voidless hermetic glass packaging per Method 2032, and screening including burn-in, temperature cycling, and surge testing. The "JANTXV" prefix explicitly denotes this qualification level, and the JANTXV1N6470US/TR data sheet cites compliance in Section 1.
What is the thermal resistance of JANTXV1N6470US/TR, and how does it affect PCB layout?
The JANTXV1N6470US/TR has a thermal resistance of 20.0 °C/W from junction to end cap. Because it uses a hard-glass MELF package with tungsten slugs and copper end caps, heat must be conducted through solder joints into large copper planes. For reliable 1500 W surge handling, PCB layout must provide ≥25 mm² of 2-oz copper per terminal, with no thermal relief on pads. The JANTXV1N6470US/TR datasheet Figure 4 shows recommended pad dimensions and spacing to maintain thermal integrity.
Does JANTXV1N6470US/TR meet IEC61000-4-2 and IEC61000-4-4 standards?
Yes, JANTXV1N6470US/TR provides ESD and EFT protection per IEC61000-4-2 (±15 kV air, ±8 kV contact) and IEC61000-4-4 (40 A, 5/50 ns), respectively, as stated in the Microsemi data sheet Section "Applications / Benefits". Its triple-layer passivation and low leakage (<1000 µA at 6 V) ensure consistent performance across these tests. The JANTXV1N6470US/TR achieves this without external filtering, making it suitable for compact avionics modules.
What is the polarity marking and mounting orientation for JANTXV1N6470US/TR?
JANTXV1N6470US/TR uses cathode-band polarity marking: a painted band on the glass body identifies the cathode terminal, which must connect to the protected line (e.g., 28 V bus). The anode connects to system ground. Its square-end-cap terminals require alignment parallel to PCB traces, with 0.090 inch center adhesive spot optional per data sheet Page 3. Mounting orientation does not affect electrical performance, but correct polarity is essential-reverse connection renders the JANTXV1N6470US/TR ineffective.
