Product details
Overview
NRVS3MB from onsemi is a surface-mount glass-passivated silicon rectifier diode rated for 3 A average forward current and 1000 V repetitive peak reverse voltage, with maximum forward voltage of 1.15 V at 3 A and AEC-Q101 qualification for automotive applications. It operates across −55 °C to +150 °C junction temperature and features MSL 1 moisture sensitivity per J-STD-020.
For engineers reviewing the NRVS3MB datasheet, pinout, applications, or equivalent options, key selection criteria include its 1000 V blocking capability, 80 A non-repetitive surge rating, low VF for thermal efficiency, UL 94V-0 flammability compliance, and automotive-grade qualification under AEC-Q101.
Technical Context
The NRVS3MB is a standard recovery rectifier (not fast or ultrafast), evidenced by its 1.5 µs typical reverse recovery time (trr) under IF = 0.5 A, IR = 1 A, Irr = 0.25 A test conditions. Its junction capacitance is 40 pF at 4 V and 1 MHz, and it exhibits 250 µA max reverse leakage at 125 °C - critical for high-temperature power supply hold-up and snubberless flyback designs.
Thermal performance is defined by 148 °C/W junction-to-ambient resistance on FR-4 PCB (76.2 mm × 114.3 mm), and 14 °C/W junction-to-lead resistance. The device uses SMB package (Case 403AF), with anode and cathode terminals clearly marked per polarity diagram.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports input rectification in 800 VAC line-derived industrial SMPS or DC-link protection in motor drives. |
| IF(AV) | 3 A - enables continuous conduction mode operation in 36–48 V output, ~60 W offline flyback or forward converters. |
| VF (max) | 1.15 V @ 3 A - limits conduction loss to ≤3.45 W, reducing heatsink requirements in space-constrained layouts. |
| IFSM | 80 A @ 8.3 ms - withstands cold-start surges and lightning-induced transients without failure. |
| trr (typ) | 1.5 µs - suitable for line-frequency and low-frequency (<100 kHz) switching applications; not recommended for >200 kHz PFC stages. |
| TJ range | −55 °C to +150 °C - validated for under-hood automotive environments and industrial enclosures without derating. |
| MSL Level | MSL 1 - allows unlimited floor life and standard reflow without baking, simplifying SMT manufacturing. |
Pinout & Package
SMB package (Case 403AF), JEDEC DO-214AA-compliant outline with 2.20 mm × 4.70 mm body, 2.65 mm height, and gull-wing leads. Cathode marked by band on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Output terminal for rectified DC | Connected to load/DC bus; polarity marking ensures correct orientation during automated placement. |
| 2 (Anode) | AC input terminal | Accepts AC waveform from transformer secondary or bridge input; must be routed with adequate creepage for 1000 V isolation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances long-term reliability and humidity resistance in automotive under-hood and industrial outdoor enclosures. |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics requiring PPAP documentation and zero-defect manufacturing traceability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NRVBS3MB | Same VRRM (1000 V), IF(AV) (3 A), and SMB package; differs only in marking code - NRVBS3MB is obsolete per onsemi discontinuation notice (page 3). | Identical functional replacement but no longer in production; NRVS3MB is current qualified version with updated control flow. | Select NRVS3MB for new designs requiring active support, AEC-Q101 documentation, and guaranteed supply continuity. |
| STTH3L06S | 600 V VRRM (vs. 1000 V), same 3 A IF(AV), SMB package, but faster trr (≤75 ns) and higher VF (1.7 V typ). | Suitable for 400 VAC systems where lower voltage rating is acceptable; not usable in 1000 V applications due to insufficient blocking margin. | Choose STTH3L06S only when system peak reverse voltage ≤600 V and fast recovery is required; NRVS3MB remains mandatory for ≥800 VAC inputs. |
Compared with NRVBS3MB and STTH3L06S, the NRVS3MB uniquely delivers 1000 V blocking with AEC-Q101 qualification and MSL 1 handling - making it the sole viable option for automotive and industrial 1000 V rectification where long-term supply assurance and automotive process controls are mandatory.

FAQ
What is the maximum junction temperature rating for NRVS3MB?
The NRVS3MB has an operating junction temperature range of −55 °C to +150 °C, verified per absolute maximum ratings table in the official datasheet (S3MB/D, Rev. 6). This rating applies across the full 3 A average forward current and 1000 V reverse voltage range, enabling use in under-hood automotive locations and sealed industrial enclosures without additional derating.
Is NRVS3MB pin-compatible with other S3x series diodes like S3AB or S3KB?
Yes - all S3x series diodes including NRVS3MB share identical SMB package (Case 403AF) dimensions, lead pitch, and 2-pin anode/cathode configuration. However, voltage ratings differ: NRVS3MB is rated for 1000 V VRRM, while S3AB is 50 V and S3KB is 800 V. Physical compatibility does not imply electrical interchangeability.
Does NRVS3MB require pre-reflow baking before SMT assembly?
No - NRVS3MB is rated MSL 1 per J-STD-020, meaning it has unlimited floor life and may be placed directly into reflow soldering without prior baking. This eliminates process steps and moisture-related defects in high-volume manufacturing lines, confirmed in the Thermal Characteristics section of the S3MB/D datasheet.
What is the reverse recovery time specification for NRVS3MB?
The NRVS3MB has a typical reverse recovery time (trr) of 1.5 µs, measured at IF = 0.5 A, IR = 1 A, and Irr = 0.25 A. This value is specified in the Electrical Characteristics table and confirms its classification as a standard recovery rectifier - appropriate for line-frequency and low-switching-frequency applications, not high-frequency PFC stages.
Is NRVS3MB suitable for use in medical equipment power supplies?
NRVS3MB is not intended for life-support or Class 3 medical devices per onsemi's disclaimer (page 4). While it meets RoHS, UL 94V-0, and AEC-Q101, onsemi explicitly excludes use in FDA Class 3 medical devices or implantables. For medical-grade power supplies, consult onsemi's dedicated medical portfolio and verify compliance with IEC 60601-1 edition 3.2.
