Product details
Overview
ES2BAHR3G from Taiwan Semiconductor is a 2A, 100V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35ns reverse recovery time, 0.95V forward voltage at 2A/25°C, and 50A peak surge current. It serves as a freewheeling or snubber diode in high-frequency DC-DC converters.
For engineers reviewing the ES2BAHR3G datasheet, ES2BAHR3G pinout, ES2BAHR3G application, or ES2BAHR3G equivalent, key selection criteria include VRRM = 100 V, IF = 2 A, trr = 35 ns, VF = 0.95 V, and DO-214AC thermal performance (RθJA = 75 °C/W).
Technical Context
This single-die silicon rectifier uses glass-passivated junction technology to achieve stable switching behavior under repetitive 8.3ms half-sine surge conditions. Its low-profile SMA package supports automated placement and meets J-STD-020 moisture sensitivity level 1.
The device operates across –55°C to +150°C junction temperature range with 20°C/W junction-to-lead thermal resistance. Reverse leakage remains ≤10 µA at 25°C and ≤350 µA at 125°C under rated VR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse blocking voltage for reliable operation in 100 V rail applications |
| IF | 2 A - Continuous average forward current rating defining steady-state power dissipation capability |
| trr | 35 ns - Ultra-fast recovery enabling high-frequency switching (>100 kHz) with minimal switching loss |
| VF | 0.95 V @ 2 A, 25°C - Low conduction loss directly reducing heat generation in compact layouts |
| IFSM | 50 A - Peak surge current handling for transient load events without bond-wire failure |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient, critical for heatsink-less PCB-level thermal design |
Pinout & Package
Package: DO-214AC (SMA), low-profile surface-mount case with matte tin-plated leads, polarity indicated by cathode band, weight ≈ 0.060 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit; requires trace width sufficient for 2 A continuous current |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to higher-potential node; must maintain clearance per 100 V working voltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures long-term reliability and stable VF/IR performance under humidity and thermal cycling |
| Super fast recovery (35 ns) | Reduces reverse recovery charge (Qrr) to minimize EMI and switching losses in SMPS |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow, supporting standard SMT assembly flow |

Applications
| DC-DC Converter | Switching Inverter |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated 48 V–12 V buck-derived converters. IC Role / Device Role / Timing Role: Freewheeling diode providing unidirectional current path during high-side switch off-time.

IC Role / Device Role / Timing Role: Input rectifier for 100 V-rated auxiliary winding feeding control IC bias rails. Use Value: VRRM = 100 V matches typical auxiliary winding peak voltage, avoiding overdesign and cost penalty. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R01 | VRRM = 100 V, trr = 30 ns, VF = 0.92 V @ 2 A, DO-214AC | Slightly faster recovery but identical voltage/current ratings | Preferred where <30 ns trr is required for >300 kHz designs |
| MBR2100 | VRRM = 100 V, Schottky structure, VF = 0.82 V @ 2 A, trr = not applicable | No reverse recovery; higher leakage (≤500 µA @ 125°C) | Used when ultra-low VF outweighs leakage sensitivity in low-temperature environments |
Compared with STTH2R01 and MBR2100, ES2BAHR3G offers balanced trade-offs: lower cost than STTH2R01, superior high-temperature leakage vs. MBR2100, and proven robustness in industrial surge environments per JESD 201 Class 2 whisker testing.

FAQ
What is the maximum junction temperature rating for ES2BAHR3G?
The ES2BAHR3G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed industrial power supplies. Derating begins above 25°C ambient per the forward current derating curve in the ES2AA–ES2JA datasheet. The device maintains specified electrical performance up to this limit when thermal design respects RθJA = 75 °C/W.
Does ES2BAHR3G meet RoHS and halogen-free requirements?
Yes, ES2BAHR3G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound satisfies UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002 solderability standards. These qualifications are confirmed in the official Taiwan Semiconductor ES2AA–ES2JA datasheet Version M2102, page 1.
What is the reverse recovery time (trr) test condition for ES2BAHR3G?
The reverse recovery time for ES2BAHR3G is measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table. This standardized condition ensures consistent comparison across the ES2x family. The typical trr value is 35 ns, with no maximum specified - indicating guaranteed performance within this typical value under defined test setup.
Is ES2BAHR3G suitable for use in automotive applications?
ES2BAHR3G is not qualified to AEC-Q101 or automotive-grade reliability standards. Taiwan Semiconductor explicitly states in the datasheet notice that ES2AA–ES2JA products are "not designed for use in medical, life-saving, or life-sustaining applications." While its –55°C to +150°C operating range overlaps automotive under-hood requirements, qualification data and PPAP documentation are not provided for ES2BAHR3G.
What does the 'R3G' suffix indicate in ES2BAHR3G?
The 'R3G' suffix in ES2BAHR3G denotes tape-and-reel packaging: R3 = 7,500 units per reel, G = green compound (halogen-free). This matches the Ordering Information table in the ES2AA–ES2JA datasheet, which specifies "ES2xA" ordering code with DO-214AC package and "7,500 / Tape & Reel" packing format. No functional difference exists between ES2BAHR3G and ES2BA.
