Product details
Overview
NRVBA130LNT3G from onsemi is a surface-mount Schottky power rectifier in SMA package, rated for 30 V reverse voltage and 1.0 A average forward current, with low 0.41 V forward voltage at 1.0 A and 25 A non-repetitive surge capability-ideal for automotive polarity protection and DC-DC converter freewheeling diodes.
For engineers reviewing the NRVBA130LNT3G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, MSL1 rating, 0.35 V VF at 2.0 A/100°C, 1.0 mA IR at 30 V/25°C, and guardring-enhanced over-voltage robustness in compact SMA outline.
Technical Context
This device uses epitaxial Schottky barrier construction with oxide passivation and metal overlay contact to achieve fast switching and low conduction loss. Its junction-to-lead thermal resistance of 35°C/W enables reliable operation up to 125°C junction temperature under 1.0 A DC load.
The integrated guardring structure provides enhanced transient over-voltage immunity, while the SMA package's J-bend leads support automated placement and meet UL 94 V-0 flammability rating. Polarity is marked by cathode band or notch per JEDEC standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 24 V automotive systems. |
| IO (TC = 105°C) | 1.0 A - Continuous forward current rating at 105°C case temperature; sets PCB copper area and heatsinking requirements. |
| VF @ 1.0 A, 25°C | 0.41 V - Low forward drop reduces conduction loss and improves efficiency in high-frequency SMPS outputs. |
| IR @ 30 V, 25°C | 1.0 mA - Reverse leakage level impacts standby power in battery-backed circuits and polarity protection paths. |
| TJ Operating Range | −55°C to +125°C - Automotive-grade junction temperature range supports under-hood and engine-control module deployment. |
| MSL Level | Level 1 - No floor life limitation; allows indefinite dry pack storage and eliminates bake requirements before reflow. |
| dv/dt Rating | 10,000 V/s - High voltage slew rate immunity prevents false turn-on in fast-switching converters. |
Pinout & Package
SMA (Case 403D) surface-mount package with molded epoxy body, 70 mg weight, and J-bend terminations. Cathode identified by polarity band or notch; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBRA130LT3G | Same electrical specs and package; differs only in marking prefix and internal traceability controls. | No functional difference; not qualified to AEC-Q101 or PPAP capable. | Select NRVBA130LNT3G for automotive production; MBRA130LT3G for industrial prototypes where qualification is not required. |
| SS13 | Same 30 V/1 A rating but higher VF (0.5 V typ), no guardring, and no AEC-Q101 validation. | Limited to consumer-grade power supplies; unsuitable for automotive or safety-critical systems. | Use SS13 only in cost-sensitive, non-automotive designs with relaxed reliability and surge requirements. |
Compared with MBRA130LT3G and SS13, the NRVBA130LNT3G delivers guaranteed automotive qualification, superior surge robustness via guardring, and tighter VF consistency across temperature-making it the sole choice for production-grade vehicle electronics requiring PPAP compliance.

FAQ
What is the maximum junction temperature rating for NRVBA130LNT3G?
The NRVBA130LNT3G has a specified operating junction temperature range of −55°C to +125°C. This rating is validated per AEC-Q101 stress tests and supports deployment in under-hood automotive environments. Thermal derating curves in the datasheet show that average forward current drops to ~0.6 A at TC = 125°C, confirming sustained operation within this limit when properly mounted.
Is NRVBA130LNT3G pin-compatible with MBRA130LT3G?
Yes, NRVBA130LNT3G is physically and electrically pin-compatible with MBRA130LT3G-both use identical SMA (Case 403D) packaging and share the same anode/cathode pinout. However, NRVBA130LNT3G adds AEC-Q101 qualification, PPAP capability, and enhanced process controls; MBRA130LT3G lacks these automotive-specific validations.
Does NRVBA130LNT3G require special handling during PCB assembly?
No special handling is required for NRVBA130LNT3G during PCB assembly. It is rated MSL1 (unlimited floor life), compatible with standard lead-free reflow profiles (peak 260°C for ≤10 seconds), and features solderable terminals per J-STD-020. The SMA package's J-bend leads support automated pick-and-place with standard nozzle tooling.
What is the reverse leakage current of NRVBA130LNT3G at 30 V and 100°C?
At VR = 30 V and TJ = 100°C, the NRVBA130LNT3G exhibits a maximum reverse current (IR) of 12 mA. This value is specified in the Electrical Characteristics table and reflects worst-case leakage under elevated temperature and full-rated reverse bias-critical for evaluating standby power loss in always-on automotive modules.
How does the guardring in NRVBA130LNT3G improve reliability?
The guardring in NRVBA130LNT3G enhances edge termination robustness, suppressing premature avalanche breakdown at the silicon periphery during voltage transients. This design feature increases the device's dv/dt rating to 10,000 V/s and improves survivability against load-dump spikes and ESD events-directly supporting AEC-Q101's over-voltage stress requirements.
