Product details
Overview
HSB83-90TL-E from Renesas Electronics (formerly Hitachi) is a silicon epitaxial planar switching diode in CMPAK (SC-70) package, rated for 250 V reverse voltage, 300 mA peak forward current, and 100 ns reverse recovery time; used in high-voltage DC-DC converter flyback snubbers and offline auxiliary power supply rectification.
For engineers reviewing the HSB83-90TL-E datasheet, HSB83-90TL-E pinout, HSB83-90TL-E application, or HSB83-90TL-E equivalent, key selection criteria include VR = 250 V, trr ≤ 100 ns, VF ≤ 1.2 V at 100 mA, IR ≤ 0.2 µA at 250 V, and SC-70 footprint compatibility with high-density PCB layouts.
Technical Context
This diode employs an epitaxial planar structure optimized for fast switching under high-voltage blocking conditions. Its low junction capacitance (3.0 pF at 0 V) and controlled minority-carrier lifetime enable clean turn-off in 100–500 kHz SMPS snubber networks.
The device operates with a maximum junction temperature of 125°C and supports continuous average rectified current of 100 mA. Non-repetitive surge capability reaches 2 A for 10 ms, allowing tolerance to transient overloads in unregulated auxiliary rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 250 V - Sustains full-rated blocking voltage in offline 230 VAC-derived circuits without derating |
| trr (Reverse Recovery Time) | 100 ns - Enables efficient operation up to 500 kHz switching frequencies with minimal switching loss |
| VF (Forward Voltage) | ≤1.2 V at IF = 100 mA - Limits conduction loss in low-current auxiliary bias windings |
| IR (Reverse Current) | ≤0.2 µA at VR = 250 V - Ensures negligible leakage in high-impedance feedback or sensing paths |
| C (Junction Capacitance) | 3.0 pF at VR = 0 V, f = 1 MHz - Minimizes capacitive coupling noise in gate-drive or signal-path snubbers |
| Package | CMPAK (JEDEC SC-70) - 3-pin surface-mount outline with 1.25 mm × 2.1 mm footprint for space-constrained designs |
Pinout & Package
CMPAK (SC-70) package: ultra-compact 3-pin surface-mount outline with exposed thermal pad (not electrically connected), 1.25 mm × 2.1 mm body size, 0.65 mm pin pitch, and 0.3 mm nominal lead thickness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally isolated; no electrical function - must remain unconnected on PCB |
| 2 | Anode | Forward current entry point; connects to higher-potential node in rectifier or clamp configuration |
| 3 | Cathode | Forward current exit point; ties to reference/ground or switching node in snubber applications |
Key Features
| Feature | Design Value |
|---|---|
| High-Voltage Blocking | VR = 250 V enables direct use in 230 VAC-derived 300 VDC bus clamping without series stacking |
| Fast Switching Speed | trr ≤ 100 ns reduces turn-off energy loss in high-frequency snubbers and clamp diodes |
| Low Leakage | IR ≤ 0.2 µA at 250 V ensures stable biasing in high-impedance feedback networks |
| Miniature Surface-Mount Package | CMPAK (SC-70) allows placement adjacent to ICs in compact AC-DC controllers and gate drivers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast-switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ROHM RB520S-30T2R | VR = 30 V, trr = 4 ns, VF = 0.33 V - lower voltage, much faster, lower VF | Not suitable for >100 V blocking; limited to low-voltage synchronous rectification or logic clamping | Select only if system VR < 40 V and sub-10 ns trr required; not a replacement for HSB83-90TL-E in 230 VAC-derived rails |
| Vishay ES1DHE3/5BT | VR = 200 V, trr = 35 ns, VF = 0.95 V, SMA package - lower VR, faster trr, larger footprint | SMA requires more board area; 200 V rating needs derating in 230 VAC systems | Acceptable where 200 V VR suffices and SMA layout is acceptable; verify margin against 300 V transients |
Compared with RB520S-30T2R and ES1DHE3/5BT, the HSB83-90TL-E uniquely balances 250 V blocking, 100 ns speed, and SC-70 size-making it optimal for space-constrained 230 VAC auxiliary supplies where higher VR than ES1DHE3/5BT is mandatory and lower VR than RB520S-30T2R is insufficient.

FAQ
What is the maximum reverse voltage rating for the HSB83-90TL-E?
The HSB83-90TL-E has a rated reverse voltage (VR) of 250 V and a peak reverse voltage (VRM) of 300 V. This allows safe operation in 230 VAC-derived DC bus applications with margin for transient overvoltage. The 250 V VR rating is specified at Ta = 25°C and must be derated linearly above that ambient temperature per the datasheet's thermal curves. HSB83-90TL-E maintains this rating within its 125°C maximum junction temperature limit.
Does the HSB83-90TL-E have a functional pin 1 connection?
No - pin 1 of the HSB83-90TL-E is designated NC (No Connect) and is internally isolated with no electrical function. It must remain unconnected on the PCB layout. The active terminals are pin 2 (Anode) and pin 3 (Cathode), consistent across all HSB83-series variants in CMPAK packaging. HSB83-90TL-E's NC pin simplifies routing by eliminating need for isolation clearance or trace termination.
What is the typical reverse recovery time of the HSB83-90TL-E?
HSB83-90TL-E has a maximum reverse recovery time (trr) of 100 ns, measured at IF = IR = 30 mA, Irr = 3 mA, and RL = 100 Ω. Typical performance falls within 70–90 ns under those conditions. This value enables efficient operation in 100–500 kHz switch-mode power supplies. HSB83-90TL-E's trr specification is guaranteed across its full operating temperature range and supports predictable snubber energy dissipation.
Can the HSB83-90TL-E be used in place of a standard 1N4007 diode?
No - the HSB83-90TL-E is not a drop-in replacement for the 1N4007. While both are rectifiers, the HSB83-90TL-E is a fast-switching, surface-mount diode (trr ≤ 100 ns, VR = 250 V, SC-70 package), whereas the 1N4007 is a slow general-purpose through-hole diode (trr ≈ 30 µs, VR = 1000 V, DO-41). HSB83-90TL-E's speed and package make it unsuitable for line-frequency rectification but ideal for high-frequency snubbing where 1N4007 would fail catastrophically.
What is the junction-to-ambient thermal resistance (RθJA) of the HSB83-90TL-E?
The datasheet for HSB83-90TL-E does not specify RθJA; only absolute maximum ratings (Tj = 125°C, Tstg = –55 to +125°C) and electrical characteristics are provided. Thermal performance depends heavily on PCB copper area, solder mask opening, and airflow. For reliable operation at IO = 100 mA, design guidelines recommend ≥25 mm² of 1-oz copper connected to pins 2 and 3. HSB83-90TL-E's small SC-70 footprint necessitates careful thermal layout - unlike larger packages, its RθJA cannot be assumed without board-specific simulation or measurement.
