Product details

Overview

ES1DHM3_A/H from Vishay General Semiconductor is a surface-mount ultrafast plastic rectifier diode in SMA (DO-214AC) package, rated for 200 V repetitive peak reverse voltage (V_RRM), 1.0 A average forward current (I_F(AV)), and 15 ns reverse recovery time (t_rr), optimized for high-frequency freewheeling in automotive DC/DC converters.

For engineers reviewing the ES1DHM3_A/H datasheet, ES1DHM3_A/H pinout, ES1DHM3_A/H application, or ES1DHM3_A/H equivalent, this part delivers verified ultrafast switching, AEC-Q101 qualification, halogen-free RoHS compliance, and low 0.92 V forward voltage at 1.0 A - critical for efficiency-critical 12 V–48 V automotive power stages.

Technical Context

The ES1DHM3_A/H is a single silicon PN junction diode with glass-passivated chip construction, enabling stable operation up to 150 °C junction temperature and robust 30 A non-repetitive surge capability (I_FSM). Its 15 ns t_rr (measured at I_F = 0.5 A, I_R = 1.0 A, I_RR = 0.25 A) supports >100 kHz switching frequencies in SMPS topologies.

Designed for automotive-grade reliability, ES1DHM3_A/H carries the HM3 suffix indicating halogen-free, RoHS-compliant, and AEC-Q101 qualified construction, with MSL Level 1 moisture sensitivity and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ES1DHE3_A/H	RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification	Suitable for commercial/industrial SMPS where automotive qualification is not required	Select when cost sensitivity outweighs halogen-free or automotive compliance needs
SB120-E3/57T	Same V_RRM (200 V) and I_F(AV) (1.0 A), but 35 ns t_rr and no AEC-Q101 rating	Acceptable for lower-frequency (<100 kHz) industrial power supplies with relaxed EMI targets	Choose only if reduced switching speed and non-automotive qualification are acceptable

Compared with ES1DHE3_A/H and SB120-E3/57T, ES1DHM3_A/H uniquely combines AEC-Q101 qualification, halogen-free construction, and 15 ns t_rr - making it the only option qualified for safety-critical 48 V automotive power stages requiring zero rework risk and full environmental compliance.

FAQ

What is the maximum junction temperature rating for ES1DHM3_A/H?

The ES1DHM3_A/H has a maximum junction temperature (T_J) rating of +150 °C, validated per Vishay's thermal characterization and supported by its R_θJA of 85 °C/W on standard 5.0 mm × 5.0 mm PCB copper pads. This allows reliable operation in under-hood automotive environments where ambient temperatures reach 125 °C, provided proper thermal design is implemented. The ES1DHM3_A/H maintains specified electrical parameters across its full -55 °C to +150 °C operating range.

Is ES1DHM3_A/H pin-compatible with ES1DHE3_A/H?

Yes, ES1DHM3_A/H is mechanically and electrically pin-compatible with ES1DHE3_A/H - both use identical SMA (DO-214AC) package outlines, anode/cathode terminal assignments, and polarity marking (cathode band). However, ES1DHM3_A/H adds halogen-free construction and AEC-Q101 qualification, while ES1DHE3_A/H is RoHS-compliant only. No PCB layout change is needed when upgrading from ES1DHE3_A/H to ES1DHM3_A/H in automotive designs.

What does the "HM3" suffix mean in ES1DHM3_A/H?

The "HM3" suffix in ES1DHM3_A/H indicates halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. "H" denotes the tape-and-reel packaging format (1800 units per 7″ reel), "M3" specifies halogen-free molding compound and plating, and "A/H" reflects the revision code and packaging variant. This distinguishes ES1DHM3_A/H from base variants like ES1D-E3 (commercial RoHS) or ES1DHE3 (AEC-Q101 but not halogen-free).

Does ES1DHM3_A/H meet J-STD-020 moisture sensitivity requirements?

Yes, ES1DHM3_A/H meets J-STD-020 Moisture Sensitivity Level (MSL) 1, with a maximum lead finish reflow peak temperature of 260 °C. This means the device has unlimited floor life and may be placed directly into reflow soldering without pre-baking, simplifying manufacturing flow for high-volume automotive electronics assembly. The qualification is confirmed in Vishay Document Number 88586, Revision 01-Apr-2020.

What is the reverse recovery charge (Q_rr) of ES1DHM3_A/H at 100 °C?

The reverse recovery charge (Q_rr) of ES1DHM3_A/H is 25 nC at T_J = 100 °C, measured under conditions of I_F = 0.6 A, V_R = 30 V, dI/dt = 50 A/μs, and I_RR = 10 % I_RM. This elevated Q_rr versus the 10 nC value at 25 °C reflects increased minority carrier lifetime at higher junction temperatures - a key parameter for snubber loss calculation and EMI filtering in high-temperature automotive power stages using ES1DHM3_A/H.
