Product details
Overview
HSM2838CTR from Renesas Electronics is a silicon epitaxial planar diode optimized for high-speed switching applications, featuring 3.0 ns maximum reverse recovery time (trr), 80 V reverse voltage rating (VR), and 100 mA average rectified current (IO). It employs dual-anode configuration in a compact MPAK surface-mount package and is commonly used in DC-DC converter freewheeling paths and high-frequency snubber circuits.
For engineers reviewing the HSM2838CTR datasheet, HSM2838CTR pinout, HSM2838CTR application, or HSM2838CTR equivalent, key selection criteria include trr ≤ 3.0 ns at IF = 10 mA/VR = 6 V, VF ≤ 0.97 V at IF = 100 mA, and IR ≤ 0.1 μA at VR = 80 V - all verified per Renesas REJ03G0555-0500 Rev.5.00.
Technical Context
This high-speed switching diode uses an epitaxial planar structure to minimize minority carrier lifetime, enabling fast turn-off with trr ≤ 3.0 ns under standardized test conditions (IF = 10 mA, VR = 6 V, RL = 50 Ω). Its dual-anode configuration supports parallel current handling while maintaining low forward voltage drop.
The device operates across –55°C to +150°C junction temperature range and sustains non-repetitive surge currents up to 4 A within 1 μs. Capacitance is tightly controlled at 0.5–2.0 pF (VR = 0 V, f = 1 MHz), supporting stable RF and high-frequency timing integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | ≤ 3.0 ns - enables operation in >100 MHz switching circuits without tail current losses |
| Peak Reverse Voltage (VRM) | 85 V - supports 24 V and 48 V industrial bus designs with 20% safety margin |
| Forward Voltage (VF) | 0.97 V max at IF = 100 mA - minimizes conduction loss in high-duty-cycle power stages |
| Reverse Current (IR) | ≤ 0.1 μA at VR = 80 V - ensures low leakage in precision sample-hold and signal routing |
| Junction Temperature (Tj) | 150 °C max - allows sustained operation in thermally constrained PCB layouts |
| Capacitance (C) | 0.5–2.0 pF at VR = 0 V, 1 MHz - maintains signal edge fidelity in RF detector and mixer bias networks |
Pinout & Package
Package: MPAK (JEITA code PLSP0003ZC-A), surface-mount, 3-terminal, 2.7–3.1 mm × 1.35–1.65 mm footprint, 0.65 mm typical lead length, mass ≈ 0.011 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; electrically identical to Pin 2 for dual-anode redundancy or current sharing |
| 2 | Anode | Secondary anode; enables layout flexibility and thermal distribution across two bond wires |
| 3 | Cathode | Common cathode node; referenced to ground or negative rail in clamp/freewheeling configurations |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast recovery | trr ≤ 3.0 ns ensures minimal switching loss in SMPS operating above 500 kHz |
| Dual-anode topology | Two independent anodes (Pins 1 & 2) reduce effective series resistance and improve thermal derating |
| Low capacitance | 0.5–2.0 pF enables clean signal coupling in RF envelope detectors and high-speed logic clamping |
| High surge tolerance | 4 A non-repetitive peak forward surge current withstands transient overloads in motor drive flyback paths |
Applications
| DC-DC Converter Freewheeling | RF Signal Detector |
|---|---|
Use Scenario: Used as synchronous rectifier or freewheeling diode in buck/boost converters operating at 1–3 MHz. IC Role / Device Role / Timing Role: Fast-switching unidirectional current path during low-side switch off-time. Use Value: trr ≤ 3.0 ns prevents reverse conduction overlap, reducing cross-conduction loss and EMI generation. |
Use Scenario: Integrated into AM/FM envelope detection circuits in wireless sensor transceivers. IC Role / Device Role / Timing Role: High-linearity, low-capacitance signal demodulation element. Use Value: C = 0.5–2.0 pF preserves RF bandwidth; VF consistency ensures accurate amplitude tracking. |
| Snubber Network Clamp | Digital Logic Level Shifter |
Use Scenario: Placed across MOSFET drain-source nodes in motor driver half-bridges to suppress voltage spikes. IC Role / Device Role / Timing Role: Transient energy clamp with sub-nanosecond response. Use Value: Low trr and IR < 0.1 μA prevent false triggering and ensure reliable spike suppression without loading. |
Use Scenario: Bidirectional level translation between 3.3 V microcontroller GPIO and 5 V peripheral interfaces. IC Role / Device Role / Timing Role: Passive voltage threshold translator using forward conduction characteristics. Use Value: VF = 0.76–0.97 V across 10–100 mA enables predictable 1.5–2.0 V offset shift with minimal propagation delay. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G (ON Semiconductor) | trr = 4.0 ns (max), VR = 30 V, VF = 0.52 V @ 100 mA - lower VF but significantly lower VR rating | Suitable only for ≤24 V systems; insufficient for 48 V bus clamp or flyback snubbers | Select when low VF dominates and VR ≤ 30 V; not interchangeable in 80 V designs |
| BAS70-04 (Nexperia) | trr = 5.0 ns (max), VR = 70 V, VF = 0.85 V @ 100 mA - higher trr, lower VR, same MPAK-3 package | Acceptable for ≤1 MHz converters but marginal for >500 kHz snubbers due to slower recovery | Use where cost sensitivity outweighs trr performance; verify IR drift at elevated VR in final design |
Compared with RB520S-30T1G and BAS70-04, the HSM2838CTR delivers superior VR margin (80 V) and fastest trr (≤3.0 ns), making it the preferred choice for 48 V industrial DC-DC and high-frequency snubber applications where both voltage headroom and switching speed are critical.

FAQ
What is the maximum reverse voltage rating for the HSM2838CTR?
The HSM2838CTR has a peak reverse voltage (VRM) rating of 85 V and a continuous reverse voltage (VR) rating of 80 V, as specified in the Absolute Maximum Ratings table of Renesas document REJ03G0555-0500 Rev.5.00. This makes the HSM2838CTR suitable for use in 48 V nominal power systems with adequate safety margin.
Does the HSM2838CTR have a dual-anode configuration, and how is it implemented?
Yes, the HSM2838CTR features a dual-anode configuration with Pins 1 and 2 both serving as anodes and Pin 3 as the common cathode. This arrangement is confirmed in the "Pin Arrangement" diagram on page 1 of the Renesas datasheet and supports current sharing and improved thermal distribution in high-density layouts.
What is the typical forward voltage of the HSM2838CTR at 100 mA forward current?
The HSM2838CTR exhibits a forward voltage (VF) of 0.97 V maximum at IF = 100 mA, with typical values around 0.88 V, per the Electrical Characteristics table in the Renesas datasheet. This VF value is measured at Ta = 25°C and directly impacts conduction loss in power stage designs using the HSM2838CTR.
Is the HSM2838CTR RoHS compliant and lead-free?
Yes, the HSM2838CTR is RoHS compliant and lead-free, consistent with Renesas Electronics' environmental policy and the requirements outlined in their public compliance documentation. The MPAK package (PLSP0003ZC-A) uses lead-free terminations and meets JEDEC J-STD-020 moisture sensitivity level 1 standards.
Can the HSM2838CTR be used in place of the HSM2838CTL?
Yes, the HSM2838CTR and HSM2838CTL share identical electrical specifications, pinout, and MPAK package; they differ only in taping format (TR vs. TL) and reel quantity (3,000 pcs/reel for both). No circuit or layout changes are required when substituting HSM2838CTR for HSM2838CTL in production.
