Product details

Overview

ES2GHE3_A/H from Vishay General Semiconductor is an AEC-Q101-qualified surface-mount ultrafast plastic rectifier in SMB (DO-214AA) package, rated for 400 V repetitive peak reverse voltage (V_RRM), 2.0 A average forward current (I_F(AV)), and 35 ns reverse recovery time (t_rr), used for high-frequency freewheeling and rectification in automotive DC/DC converters.

For engineers reviewing the ES2GHE3_A/H datasheet, ES2GHE3_A/H pinout, ES2GHE3_A/H application, or ES2GHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C maximum junction temperature, 50 A non-repetitive surge rating, low 1.1 V forward voltage at 2.0 A, and SMB package compatibility with automated SMT assembly.

Technical Context

This device is a single-die, single-anode/cathode silicon PN junction rectifier optimized for fast switching in high-frequency power conversion. Its 35 ns reverse recovery time (measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 I_RM) and 50 nC stored charge (Q_rr) enable reduced switching losses in SMPS topologies.

The ES2GHE3_A/H uses glass-passivated pellet chip construction, supports lead-free soldering per J-STD-002/JESD 22-B102, and meets MSL level 1 per J-STD-020 with 260 °C peak reflow profile - confirming suitability for high-reliability automotive PCB assembly.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - supports input stages up to 280 V RMS in offline AC/DC or 400 V bus in automotive 48 V systems
I_F(AV)	2.0 A at T_L = 110 °C - enables continuous conduction mode operation in compact 1–2 W output converters
t_rr	35 ns - minimizes turn-off loss and EMI generation in >100 kHz switching applications
V_F @ 2.0 A	1.1 V - reduces conduction loss to ~2.2 W at full load, easing thermal design in confined layouts
Q_rr	50 nC - limits reverse recovery energy dissipation during hard-switched transitions
T_J(max)	150 °C - allows operation in under-hood automotive environments without derating below 110 °C board temperature
R_θJA	75 °C/W - requires ≥5 mm × 5 mm copper pad for safe operation at full I_F(AV)

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultrafast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R04DJF	TO-277 package (SMD), 400 V V_RRM, 30 ns t_rr, 1.15 V V_F, no AEC-Q101 rating	Higher-speed alternative but lacks automotive qualification and has different thermal pad layout	Select when faster recovery is critical and automotive qualification is not required

FAQ

What is the maximum junction temperature rating for ES2GHE3_A/H?

The ES2GHE3_A/H has a maximum junction temperature (T_J(max)) of 150 °C, enabling reliable operation in under-hood automotive environments and high-ambient industrial settings. This rating is validated per AEC-Q101 stress testing and allows full 2.0 A average current derating only above 110 °C board temperature. The ES2GHE3_A/H maintains stable electrical parameters across this range when mounted on a 5 mm × 5 mm copper pad.

Is ES2GHE3_A/H pin-compatible with ES2FHE3_A/H?

Yes, ES2GHE3_A/H and ES2FHE3_A/H share identical SMB (DO-214AA) package dimensions, anode/cathode terminal locations, and polarity marking - making them mechanically interchangeable. However, ES2GHE3_A/H is rated for 400 V V_RRM, while ES2FHE3_A/H is rated for 300 V; substituting one for the other requires verification of voltage margin in the target circuit. Both carry the HE3 suffix confirming AEC-Q101 qualification.

Does ES2GHE3_A/H meet lead-free soldering standards?

Yes, ES2GHE3_A/H features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, supporting lead-free reflow soldering up to 260 °C peak temperature. It is rated MSL Level 1 per J-STD-020, meaning it can be placed directly onto PCBs without dry-pack storage or baking - simplifying manufacturing flow for high-volume automotive SMT lines using the ES2GHE3_A/H.

What is the reverse recovery time specification for ES2GHE3_A/H?

The ES2GHE3_A/H has a maximum reverse recovery time (t_rr) of 35 ns under the test condition I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 I_RM. An alternate condition (I_F = 1.0 A, dI/dt = 100 A/μs) yields 50 ns. This fast recovery minimizes switching loss and EMI in converters operating above 100 kHz, and is a key differentiator versus standard fast recovery diodes like the MUR240HE3_A/H.

How does the AEC-Q101 qualification impact ES2GHE3_A/H usage?

The AEC-Q101 qualification of ES2GHE3_A/H confirms it has passed accelerated stress tests for temperature cycling, humidity bias, HTRB, and ESD - validating suitability for automotive powertrain, chassis, and ADAS applications. Unlike commercial-grade ES2G-E3 variants, the ES2GHE3_A/H provides documented reliability data and lot-level traceability required by Tier 1 suppliers, making it mandatory for functional-safety-aware designs where the ES2GHE3_A/H is deployed.
