Product details
Overview
NRVBB2535CTLT4G from onsemi is a 35 V, 25 A dual common-cathode Schottky barrier rectifier in D2PAK (TO-263) surface-mount package, optimized for low forward voltage drop (0.41 V at 12.5 A, 125°C) and high-frequency switching power supplies, including automotive DC-DC converters and OR-ing circuits. It features AEC-Q101 qualification, 125°C maximum junction temperature, and guardring-enhanced stress protection.
For engineers reviewing the NRVBB2535CTLT4G datasheet, pinout, applications, or equivalent options, key selection criteria include its dual-center-tap configuration, low thermal resistance (RθJC = 1.0°C/W), Pb-free compliance, and suitability for high-reliability automotive and industrial power conversion where reverse recovery loss must be minimized.
Technical Context
This device implements a dual-leg Schottky barrier structure with oxide-passivated epitaxial silicon and metal overlay contact, enabling fast switching without minority-carrier storage delay. Its center-tap configuration supports synchronous rectification topologies and bidirectional current handling in half-bridge or full-wave configurations.
The D2PAK-3L package (Case 418B, Style 3) provides direct thermal path from die to heatsink tab, supporting 12.5 A average forward current at TC = 110°C. Guardring design mitigates edge breakdown under high dv/dt (10,000 V/s rated), critical for flyback and LLC resonant converter freewheeling operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 35 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating range in 12–24 V automotive systems. |
| IF(AV) | 12.5 A - Average forward current per leg at TC = 110°C; enables compact layout in space-constrained power modules. |
| VF @ 12.5 A, 125°C | 0.41 V - Low conduction loss reduces heat generation in high-duty-cycle applications like server VRMs. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; allows direct heatsinking without thermal interface material in many designs. |
| TJ max | +125°C - Maximum operating junction temperature; supports under-hood automotive environments per AEC-Q101. |
| IFSM | 150 A - Non-repetitive surge rating (60 Hz half-wave); withstands inrush currents during cold-start conditions. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM >8 kV). |
Pinout & Package
D2PAK-3L (Case 418B, Style 3) surface-mount package with isolated heatsink tab; molded epoxy body meeting UL 94 V-0; 1.7 g mass; MSL1 compliant; lead-free (Pb-free) finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Leg 1) | Input terminal for first Schottky diode leg; connects to switching node in buck or flyback secondary side. |
| 2 | Cathode (Common) | Shared cathode node for both legs; serves as output/return path; electrically tied to heatsink tab. |
| 3 | Anode (Leg 2) | Input terminal for second Schottky diode leg; enables dual-channel or center-tap transformer rectification. |
| 4 | Cathode (Common) | Redundant cathode connection; improves current sharing and thermal distribution across common node. |
Key Features
| Feature | Design Value |
|---|---|
| Center-tap configuration | Enables dual independent anodes sharing one cathode, supporting full-wave center-tapped transformer rectifiers and OR-ing diode arrays. |
| Guardring stress protection | Prevents premature edge breakdown under high dv/dt transients, improving reliability in hard-switched SMPS. |
| Low VF at high TJ | 0.41 V at 12.5 A and 125°C ensures stable efficiency across automotive temperature range without derating penalty. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, biased HTRB, and ESD robustness-no additional qualification needed. |
| Short heatsink tab | Manufactured (not sheared) tab minimizes mechanical stress and improves solder joint integrity during reflow and thermal cycling. |

FAQ
What is the pin configuration of the NRVBB2535CTLT4G?
The NRVBB2535CTLT4G uses D2PAK-3L (Case 418B, Style 3) with Pin 1 = Anode (Leg 1), Pin 2 = Cathode (Common), Pin 3 = Anode (Leg 2), Pin 4 = Cathode (Common). Both cathodes are internally tied and connected to the heatsink tab, enabling dual-anode, single-cathode operation ideal for center-tapped transformer rectification. This configuration is confirmed in the official onsemi mechanical drawing 418B-04.
Is the NRVBB2535CTLT4G suitable for automotive applications?
Yes, the NRVBB2535CTLT4G is AEC-Q101 qualified and PPAP capable, with explicit "NRVBB" prefix denoting automotive-grade manufacturing controls, site-specific change management, and extended reliability testing. It operates up to +125°C junction temperature and meets automotive ESD requirements (HBM >8 kV, MM >400 V), making it appropriate for engine control units, ADAS power supplies, and body electronics.
How does the NRVBB2535CTLT4G compare to the MBRB2535CTLT4G?
The NRVBB2535CTLT4G shares identical electrical specifications and die with the MBRB2535CTLT4G but adds AEC-Q101 qualification, PPAP capability, and enhanced process controls required for automotive production. The "NRVBB" prefix signals dedicated automotive traceability, while MBRB variants are intended for commercial/industrial use only. For automotive programs, NRVBB2535CTLT4G is the mandated version.
What is the maximum average forward current rating for the NRVBB2535CTLT4G?
The NRVBB2535CTLT4G is rated for 12.5 A average forward current per leg at case temperature TC = 110°C, as specified in the Absolute Maximum Ratings table. This rating assumes proper PCB copper area per onsemi's recommended footprint (8.38 mm × 5.08 mm thermal pad) and adequate airflow or heatsinking. Derating applies above 110°C case temperature per Figure 4 in the datasheet.
Does the NRVBB2535CTLT4G have a Pb-free finish?
Yes, the NRVBB2535CTLT4G is Pb-free and RoHS compliant, indicated by the "G" suffix in the part number and confirmed in the Mechanical Characteristics section.
