Product details

Overview

ES3JB R5G from Taiwan Semiconductor is a 3A, 600V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 1.11–1.30V forward voltage at 1.5A/25°C, 35ns reverse recovery time, and 34pF junction capacitance - deployed in high-frequency SMPS secondary-side rectification.

For engineers reviewing the ES3JB R5G datasheet, ES3JB R5G pinout, ES3JB R5G application, or ES3JB R5G equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (R_θJL = 24°C/W), moisture sensitivity level (MSL 1), RoHS/halogen-free compliance, and SMB footprint compatibility with automated placement.

Technical Context

This discrete silicon PN-junction rectifier uses glass-passivated chip construction for enhanced reliability and operates as a unidirectional current switch in DC output stages. Its super-fast trr ≤35ns enables efficient operation in 100kHz–500kHz switching converters without significant switching loss penalties.

Thermal performance is defined for PCB mounting on 10mm × 10mm copper pads: R_θJA = 84°C/W (ambient), R_θJC = 26°C/W (case), and R_θJL = 24°C/W (lead), supporting continuous 3A conduction up to T_J = 150°C with appropriate board-level heat spreading.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in high-voltage DC bus or PFC front-end applications.
I_F	3 A - Average forward current rating at T_A = 25°C; derates linearly above 25°C per published curve.
t_rr	≤35 ns - Reverse recovery time measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables high-frequency rectification with low switching loss.
V_F	1.11–1.30 V @ I_F = 1.5A, T_J = 25°C - Forward voltage drop directly impacts conduction loss and thermal load in power stage design.
C_J	34 pF @ 1MHz, V_R = 4V - Junction capacitance affects high-frequency noise coupling and snubber design in flyback/LLC topologies.
R_θJL	24 °C/W - Junction-to-lead thermal resistance; critical for estimating temperature rise under lead-mounted heatsinking or via thermal relief design.

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage super fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-ES3JBHM3/5BT	Same 600V V_RRM, 3A I_F, DO-214AA package; VF = 1.25V typ @ 1.5A, trr = 35ns - identical electrical envelope.	Qualified to AEC-Q101; suitable for automotive-grade designs where ES3JB R5G is not certified.	Select VS-ES3JBHM3/5BT when automotive qualification or extended temperature validation is required.
ON Semiconductor ES3JB	Identical parametric specs and DO-214AA package; minor marking and traceability differences; same VF/trr/R_θ values.	No functional distinction; used interchangeably in industrial SMPS where Taiwan Semiconductor sourcing is constrained.	Choose ON Semi ES3JB only if dual-sourcing strategy mandates second-source availability with no layout or thermal redesign.

Compared with Vishay VS-ES3JBHM3/5BT and ON Semi ES3JB, the ES3JB R5G offers identical core rectification performance and SMB footprint but differs in qualification scope and supply chain origin - making it optimal for cost-sensitive industrial power supplies where AEC-Q101 is unnecessary and Taiwan Semiconductor logistics are preferred.

FAQ

What is the maximum junction temperature rating for ES3JB R5G?

The ES3JB R5G has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings table. This allows continuous 3A operation in ambient temperatures up to ~70°C when mounted on a 10mm × 10mm Cu pad (R_θJA = 84°C/W). Derating curves in the ES3AB–ES3JB datasheet must be applied for higher ambient or non-standard board layouts. Thermal design should reference R_θJL = 24°C/W for lead-mounted heatsinking scenarios.

Does ES3JB R5G support lead-free reflow soldering?

Yes, ES3JB R5G supports lead-free reflow soldering per J-STD-020. Its MSL Level 1 rating means no pre-bake is required, and the matte tin-plated leads are fully compatible with Pb-free SAC305 profiles (peak temp ≤260°C, 60–90 sec above 217°C). The device's UL 94V-0 molding compound remains stable under standard reflow thermal cycles without delamination or cracking.

What is the reverse recovery time (t_rr) test condition for ES3JB R5G?

The reverse recovery time of ES3JB R5G is specified as ≤35ns under the condition: I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A, measured at T_A = 25°C. This reflects real-world switching behavior in high-frequency converters. The value is confirmed across the ES3HB–ES3JB group and is independent of voltage variant - meaning ES3JB R5G maintains the same 35ns t_rr as lower-voltage siblings despite its 600V rating.

Is ES3JB R5G halogen-free and RoHS compliant?

Yes, ES3JB R5G is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated or chlorinated flame retardants, and all homogeneous materials meet EU Directive 2011/65/EU limits for Pb, Cd, Hg, Cr(VI), PBB, and PBDE. Certificate of Compliance is available upon request from Taiwan Semiconductor or Aetrix Electronics.

How does the forward voltage of ES3JB R5G vary with temperature?

ES3JB R5G exhibits negative temperature coefficient for forward voltage: at I_F = 1.5A, V_F drops from 1.11–1.30V at 25°C to 0.85–0.98V at 125°C. This reduction lowers conduction loss at elevated junction temperatures but requires thermal-aware design - especially in sealed enclosures - since reduced V_F increases current sharing imbalance in parallel configurations.
