Product details

Overview

ESH2D-E3/52T from Vishay General Semiconductor is a surface-mount ultrafast plastic rectifier diode in SMB (DO-214AA) package, rated for 200 V repetitive peak reverse voltage (V_RRM), 2.0 A average forward current (I_F(AV)), and 25 ns reverse recovery time (t_rr). It serves as a high-efficiency freewheeling or output rectifier in switching-mode power supplies for automotive and industrial converters.

For engineers reviewing the ESH2D-E3/52T datasheet, ESH2D-E3/52T pinout, ESH2D-E3/52T application, or ESH2D-E3/52T equivalent, key selection criteria include its 200 V blocking capability, 0.93 V forward voltage at 2 A, AEC-Q101 qualification eligibility (via HE3 suffix), RoHS-compliant matte tin plating, and MSL Level 1 moisture sensitivity rating.

Technical Context

The ESH2D-E3/52T employs a glass-passivated pellet chip junction to ensure stable ultrafast switching performance and thermal robustness up to 175 °C junction temperature. Its 25 ns reverse recovery time (measured at I_F = 0.5 A, I_R = 1 A, I_rr = 0.25 A) enables high-frequency operation in SMPS topologies without excessive switching loss.

Designed as a single-anode/cathode discrete rectifier, it delivers low forward voltage drop (0.93 V @ 2 A) and high surge capability (60 A I_FSM, 8.3 ms half-sine), supporting reliable operation under transient load conditions in DC-DC converters and inverters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - supports input rectification or freewheeling in 12–48 V bus systems with 2× safety margin
I_F(AV)	2.0 A - continuous DC output current handling for mid-power SMPS stages
t_rr	25 ns - enables efficient operation at ≥100 kHz switching frequencies with minimal reverse recovery loss
V_F @ 2 A	0.93 V - reduces conduction loss to ~1.86 W per device at full load, improving thermal design margin
T_J max	175 °C - allows operation in under-hood automotive environments or sealed industrial enclosures
R_θJA	65 °C/W - requires ≤8 mm × 8 mm copper pad for thermal management at full I_F(AV)
Q_rr @ 25 °C	20 nC - limits commutation-induced voltage spikes and EMI in hard-switched converters

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R02DJF	Same SMB package, 200 V V_RRM, but 30 ns t_rr; VF = 0.95 V @ 2 A; no AEC-Q101 option	Suitable for commercial-grade SMPS where 5 ns slower recovery is acceptable	Select if cost sensitivity outweighs marginal t_rr advantage and automotive qualification is unnecessary
ON Semi MUR220SFT1G	SMB package, 200 V V_RRM, 35 ns t_rr, VF = 0.97 V @ 2 A; MSL Level 1, RoHS-compliant	Valid for general-purpose rectification but lacks AEC-Q101 path and has higher Q_rr (25 nC)	Prefer for legacy designs already qualified with ON Semi footprint; verify thermal derating due to higher R_θJA

Compared with STTH2R02DJF and MUR220SFT1G, the ESH2D-E3/52T offers the fastest documented t_rr (25 ns), lowest V_F, and defined AEC-Q101 qualification route-making it optimal for thermally constrained, high-frequency, or automotive-qualified designs where recovery speed directly impacts efficiency.

FAQ

What is the maximum junction temperature rating for the ESH2D-E3/52T?

The ESH2D-E3/52T has a maximum junction temperature (T_J) of +175 °C, enabling reliable operation in high-ambient environments such as automotive under-hood locations or sealed industrial enclosures. This rating is validated across the full operating range and supports derated current handling up to that limit, as shown in Figure 1 of the Vishay datasheet 84649. The ESH2D-E3/52T maintains stable electrical parameters-including V_F and t_rr-within this thermal envelope.

Is the ESH2D-E3/52T AEC-Q101 qualified?

The ESH2D-E3/52T itself is the commercial-grade RoHS-compliant version (E3 suffix); AEC-Q101 qualification applies only to variants with the HE3 suffix (e.g., ESH2DHE3_A/H). While the ESH2D-E3/52T shares identical die and package construction, formal AEC-Q101 test reports and automotive part numbering require the HE3 ordering code. Therefore, ESH2D-E3/52T is not AEC-Q101 qualified-but serves as the baseline for that qualified family.

What does the "/52T" in ESH2D-E3/52T indicate?

The "/52T" suffix denotes the preferred packaging configuration: 7" diameter plastic tape and reel, with 750 units per reel. This is distinct from "/5BT", which indicates 13" tape-and-reel with 3200 units. Both share the same ESH2D-E3 die and SMB package; the suffix solely specifies mechanical packaging format and quantity for automated SMT placement. The ESH2D-E3/52T is optimized for medium-volume production runs requiring standard feeder compatibility.

How does the ESH2D-E3/52T compare to the ESH2B and ESH2C variants?

The ESH2D-E3/52T differs from ESH2B and ESH2C exclusively in its 200 V V_RRM rating (vs. 100 V and 150 V respectively); all three share identical package (SMB), I_F(AV) = 2.0 A, t_rr = 25 ns, V_F = 0.93 V @ 2 A, thermal resistance, and construction. The ESH2D-E3/52T is selected when system-level transient protection or higher bus voltage tolerance is required-such as in 48 V automotive architectures or industrial 200 VDC intermediate buses.

What is the reverse recovery charge (Q_rr) of the ESH2D-E3/52T at 100 °C?

At 100 °C junction temperature, the typical reverse recovery charge (Q_rr) of the ESH2D-E3/52T is 35 nC, measured under I_F = 2 A, V_R = 30 V, dI/dt = 50 A/μs, and I_rr = 10 % I_RM. This value increases from 20 nC at 25 °C due to temperature-dependent carrier lifetime extension. Designers must account for this rise when sizing snubbers or evaluating EMI in high-temperature operating conditions for the ESH2D-E3/52T.
