Product details
Overview
ES3BBH from Taiwan Semiconductor is a 3A, 100V super fast surface-mount rectifier diode in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 0.92V forward voltage at 1.5A/25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the ES3BBH datasheet, ES3BBH pinout, ES3BBH application, or ES3BBH equivalent, key selection criteria include peak repetitive reverse voltage (100V), surge current capability (100A), thermal resistance (RθJL = 24°C/W), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance.
Technical Context
This super fast rectifier uses a glass-passivated silicon junction optimized for high-frequency switching applications. Its 35ns reverse recovery time enables efficient operation in DC-DC converters operating above 100kHz, with low forward voltage drop minimizing conduction losses.
The device supports automated SMT placement and meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1. Thermal performance is characterized on a 10mm × 10mm copper pad PCB, delivering RθJA = 84°C/W and RθJC = 26°C/W.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EWH10-M3/5AT | Same DO-214AA package; 100V VRRM, 35ns trr, but 0.97V VF @ 1.5A - 50mV higher forward drop | Identical automotive and DC-DC use cases; slightly higher conduction loss at full load | Preferred where Vishay supply chain alignment or dual-sourcing is required |
| ON Semiconductor MUR310RLG | DO-214AC (SMA) package; 100V VRRM, 35ns trr, 0.94V VF; smaller footprint but lower thermal mass (RθJA = 100°C/W) | Suitable for space-constrained designs; not recommended for sustained 3A operation without derating | Select when board area is critical and peak current is intermittent |

FAQ
What is the maximum junction temperature rating for ES3BBH?
The ES3BBH has a maximum junction temperature (TJ) rating of +150°C and a minimum of –55°C. This wide range supports operation in under-hood automotive environments and industrial power supplies. The device's thermal resistance values (RθJL = 24°C/W, RθJA = 84°C/W) are measured on a 10mm × 10mm Cu pad PCB, enabling accurate thermal design for the ES3BBH in real-world layouts.
Is ES3BBH suitable for automotive applications?
Yes, ES3BBH is AEC-Q101 qualified and explicitly listed for automotive applications including car lighting and solenoid drivers. It meets JESD201 Class 2 whisker resistance, J-STD-020 MSL Level 1, and halogen-free requirements per IEC 61249-2-21 - all verified per TSC's A2102 datasheet revision. These qualifications make ES3BBH appropriate for safety-critical and high-reliability automotive subsystems.
What is the forward voltage of ES3BBH at 3A and 25°C?
The forward voltage (VF) of ES3BBH is 1.00 V at 3.0A and 25°C, as specified in the Electrical Specifications table. At elevated temperature (125°C), VF drops to 0.84 V under the same current condition - a characteristic of silicon PN junctions that must be considered in thermal design. This value is confirmed for ES3BBH specifically, not extrapolated from adjacent variants.
Does ES3BBH have a defined reverse recovery time?
Yes, ES3BBH has a maximum reverse recovery time (trr) of 35 ns, tested at IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This parameter is explicitly listed in the "ELECTRICAL SPECIFICATIONS" section of the datasheet and distinguishes ES3BBH as a super fast rectifier - critical for minimizing switching loss and EMI in high-frequency DC-DC converters using the ES3BBH.
What package type does ES3BBH use and what are its mechanical features?
ES3BBH uses the DO-214AA (SMB) surface-mount package: low-profile, UL 94V-0 rated molding compound, matte tin-plated leads compliant with J-STD-002, and polarity indicated by a cathode band. Its mechanical outline and suggested PCB pad layout are documented in the "PACKAGE OUTLINE DIMENSIONS" section of the TSC datasheet (Version A2102). Weight is approximately 0.110g.
