Product details
Overview
NRVS1GHE from onsemi is an automotive-grade surface-mount silicon rectifier diode rated for 1 A average forward current and 400 V maximum repetitive peak reverse voltage, featuring glass-passivated junction, low-profile SOD-323EP package (height < 0.75 mm), and AEC-Q101 qualification - used in DC/DC converter output stages and automotive lighting power supplies.
For engineers reviewing the NRVS1GHE datasheet, pinout, applications, or equivalent options, key selection criteria include its 0.96–1.1 V forward voltage at 1 A, 782 ns reverse recovery time, 3 pF junction capacitance at 4 V, 20 A surge rating, and thermal resistance of 26.5 °C/W (junction-to-lead).
Technical Context
This device operates as a single-phase, unidirectional silicon PN junction rectifier optimized for high-efficiency, space-constrained automotive power conversion. Its glass-passivated chip junction ensures stable leakage performance across −55 °C to +175 °C operating range and supports reliable operation under transient overvoltage conditions.
The SOD-323EP package enables compact PCB layout with low thermal resistance to lead (26.5 °C/W) and high moisture resistance (J-STD-020 Level 1). Reverse recovery time of 782 ns reflects fast switching capability suitable for medium-frequency SMPS topologies.
Key Specifications

|---|---|
| VRRM | 400 V - Withstands repetitive reverse voltage up to 400 V without breakdown; defines maximum input/output voltage differential in flyback or buck-derived topologies. |
| IF(AV) | 1 A - Continuous average forward current handling capacity; determines usable output current in linear or switching regulator secondary-side rectification. |
| VF @ 1 A | 0.96–1.1 V - Forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle applications. |
| Trr | 782 ns - Reverse recovery time affects switching loss and EMI generation in 50–500 kHz SMPS designs. |
| CJ @ 4 V | 3 pF - Junction capacitance influences high-frequency noise coupling and snubber design in fast-switching circuits. |
| RJA | 200 °C/W - Junction-to-ambient thermal resistance indicates need for thermal relief pads or airflow in sealed enclosures. |
| IFSM | 20 A - Peak surge current rating supports inrush tolerance during cold-start or load-dump events in automotive systems. |
Pinout & Package
SOD-323EP is a 2-pin surface-mount package with cathode band marking; total height ≤ 0.75 mm, footprint 1.75 mm × 1.35 mm, compatible with standard reflow profiles (Moisture Sensitivity Level 1).

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NRVS1JHE | Higher VRRM (600 V vs. 400 V); identical package, thermal, and electrical specs otherwise. | Required where input transients exceed 400 V, e.g., 48 V industrial bus with load dump. | Select NRVS1JHE when system-level reverse voltage margin must exceed 400 V; same footprint and assembly process. |
| RB520S-40T1G | Lower VF (0.36 V typ. @ 0.1 A), Schottky architecture; lower VRRM (40 V), not AEC-Q101 qualified. | Only suitable for low-voltage (<30 V) consumer or industrial applications without automotive qualification needs. | Choose RB520S-40T1G only for non-automotive, low-VF, low-VRRM use cases; not a drop-in replacement for NRVS1GHE. |
Compared with NRVS1GHE, NRVS1JHE offers higher reverse voltage headroom without layout or thermal impact, while RB520S-40T1G trades off voltage rating and qualification for lower forward loss - making NRVS1GHE the optimal balance of automotive robustness, medium-voltage capability, and compact packaging.

FAQ
What is the maximum junction temperature rating for NRVS1GHE?
The NRVS1GHE has an operating junction temperature range of −55 °C to +175 °C, verified per AEC-Q101 stress testing. This wide range supports deployment in under-hood automotive locations and high-ambient industrial settings. The device maintains specified electrical performance across this full range, with leakage current and forward voltage characterized at both extremes. Thermal design must account for ΨJL = 26.5 °C/W to ensure TJ stays within limits under full load.
Is NRVS1GHE pin-compatible with S1GHE?
Yes, NRVS1GHE is pin-compatible with S1GHE - both use the SOD-323EP package with identical pinout (anode on pin 1, cathode on pin 2) and mechanical dimensions. The "NRV" prefix denotes automotive-specific traceability, control, and qualification (AEC-Q101, PPAP), while electrical and thermal specs match S1GHE exactly. No PCB redesign is needed when upgrading from S1GHE to NRVS1GHE in automotive programs.
Does NRVS1GHE require special handling due to moisture sensitivity?
No - NRVS1GHE is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30 °C/60% RH without dry-pack or baking requirements. This simplifies manufacturing logistics and eliminates pre-reflow bake steps, reducing assembly cost and cycle time. The SOD-323EP package construction and green mold compound contribute to this robust moisture resistance.
What is the reverse recovery time (Trr) of NRVS1GHE and how is it measured?
The NRVS1GHE has a typical reverse recovery time (Trr) of 782 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC standards. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss and EMI in SMPS designs. The measurement condition ensures repeatability and correlates with real-world behavior in 100–500 kHz converters using NRVS1GHE in secondary-side rectification.
Can NRVS1GHE be used in synchronous rectification circuits?
No - NRVS1GHE is a passive silicon PN junction rectifier, not a synchronous rectifier controller or MOSFET. It cannot be actively driven or gated like a MOSFET-based synchronous rectifier. However, it serves as a robust, low-cost alternative to synchronous solutions in medium-frequency (<300 kHz), medium-power (<15 W) applications where gate drive complexity or cost outweighs the ~2–5% efficiency gain from synchronous rectification. Its 782 ns Trr supports clean turn-off in such contexts.
