Product details
Overview
HSM221CTL from Renesas Electronics is a silicon epitaxial planar high-speed switching diode in MPAK (SC-59A) package, featuring 80 V reverse voltage rating, 3.0 ns max reverse recovery time, and 0.5–2.0 pF capacitance at 1 MHz. It serves as a fast-switching signal path diode in RF detector, sample-and-hold, and high-frequency clamp circuits.
For engineers reviewing the HSM221CTL datasheet, HSM221CTL pinout, HSM221CTL application, or HSM221CTL equivalent, key selection criteria include trr ≤ 3.0 ns, VR = 80 V, low C = 0.5–2.0 pF, NC pin configuration, and MPAK surface-mount compatibility for dense PCB layouts.
Technical Context
The HSM221CTL uses a silicon epitaxial planar structure optimized for high-speed switching, with junction design minimizing minority carrier storage to achieve trr ≤ 3.0 ns under IF = 10 mA, VR = 6 V, RL = 50 Ω test conditions. Its low capacitance (0.5–2.0 pF at VR = 0 V, f = 1 MHz) supports stable operation up to UHF frequencies.
Thermal performance is rated for junction temperatures up to 150°C, with storage range from –55°C to +150°C. The device is not intended for automotive safety-critical or life-support applications per Renesas documentation.
Key Specifications

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 |
|---|---|---|---|
| BAV99LT1G | Higher trr (4.0 ns max), same MPAK package, 70 V VR | Suitable for general-purpose high-speed switching but marginal in >300 MHz detector use | Select when cost sensitivity outweighs sub-3 ns timing requirement |
| 1N4148W | DO-35 package, trr = 4.0 ns, VR = 100 V, higher C (4 pF) | Through-hole or legacy layout compatibility; less suitable for UHF signal paths | Choose only if MPAK footprint is unavailable and thermal/power constraints permit larger package |
Compared with BAV99LT1G and 1N4148W, the HSM221CTL delivers the lowest trr (≤3.0 ns) and lowest capacitance (0.5–2.0 pF) in an MPAK package, making it optimal for UHF detector, clamp, and sampling circuits where timing integrity and parasitic minimization are critical.

FAQ
What is the maximum reverse voltage rating for the HSM221CTL?
The HSM221CTL has a maximum reverse voltage (VR) rating of 80 V and a peak reverse voltage (VRM) of 85 V. These ratings define its DC blocking capability under normal operating conditions at Ta = 25°C. Exceeding 80 V continuously may cause premature degradation; the 85 V VRM applies only to non-repetitive transient conditions. Always consult the absolute maximum ratings table in the official Renesas datasheet REJ03G0552-0600 for derating guidance.
Does the HSM221CTL have a pin 1 connection, and what is its function?
No - pin 1 of the HSM221CTL is designated No Connect (NC) and must remain unconnected in circuit layout. The active terminals are pin 2 (Anode) and pin 3 (Cathode), arranged in top-view order 2–1–3. Connecting pin 1 risks parasitic coupling or mechanical stress on the die bond wire, potentially degrading trr or C performance. This NC configuration is confirmed in the "Pin Arrangement" diagram on page 1 of REJ03G0552-0600.
What is the typical forward voltage of the HSM221CTL at 10 mA forward current?
The typical forward voltage (VF) of the HSM221CTL at IF = 10 mA is 0.76 V, with a maximum of 1.0 V at Ta = 25°C. This low VF supports efficient signal routing in low-power detector and clamp circuits. At higher currents (e.g., 100 mA), VF rises to 0.97–1.2 V, reflecting expected silicon diode behavior. All VF values are measured under specified test conditions in the Electrical Characteristics table of REJ03G0552-0600.
Can the HSM221CTL be used in automotive applications?
No - the HSM221CTL is classified by Renesas as a Standard-grade product intended for computers, office equipment, communications gear, and industrial instrumentation. It is explicitly excluded from automotive safety-critical, powertrain, or body-control modules per Renesas' quality grade definitions. For automotive use, Renesas offers separate AEC-Q101 qualified diodes; the HSM221CTL lacks required qualification testing and lifetime reliability validation for vehicle environments.
What package type does the HSM221CTL use, and is it RoHS compliant?
The HSM221CTL uses the MPAK package (JEITA code PLSP0003ZC-A), equivalent to SC-59A, with 3 terminals and a 0.011 g typical mass. Per Renesas' environmental compliance statements and product change notices, the HSM221CTL is RoHS compliant and lead-free. Full material declarations and exemption status are available in Renesas' official environmental reports - always verify latest compliance data via Renesas' website before high-volume deployment.
