Product details
Overview
HSM221C-JTL-E from Renesas Electronics is a silicon epitaxial planar diode engineered for high-speed switching applications, featuring a maximum reverse recovery time of 3.0 ns, peak reverse voltage of 85 V, and low junction capacitance of 0.5–2.0 pF at 1 MHz. It operates with forward voltage as low as 0.76 V at 10 mA and supports average rectified current up to 100 mA. This device is deployed in high-frequency signal routing circuits such as RF detector stages and fast-switching DC-DC converter snubbers.
For engineers reviewing the HSM221C-JTL-E datasheet, HSM221C-JTL-E pinout, HSM221C-JTL-E application, or HSM221C-JTL-E equivalent, key selection criteria include verified trr ≤ 3.0 ns performance under IF = 10 mA / VR = 6 V conditions, MPAK package compatibility with high-density SMT assembly, and guaranteed IR ≤ 0.1 μA at VR = 80 V for low-leakage signal path integrity.
Technical Context
The HSM221C-JTL-E employs a silicon epitaxial planar structure optimized for minimal minority-carrier storage, enabling sub-4 ns reverse recovery. Its low capacitance (typ. 0.5 pF) and tight trr distribution support stable operation in 100+ MHz signal paths without waveform distortion.
This diode functions exclusively as a unidirectional high-speed switch - not a Zener, Schottky, or avalanche device - with NC (pin 1), Anode (pin 2), and Cathode (pin 3) terminal configuration. Junction temperature rating of 150°C ensures reliability in thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | Max 3.0 ns at IF = 10 mA, VR = 6 V, RL = 50 Ω - enables clean edge transitions in >100 MHz digital and RF switching |
| Peak Reverse Voltage (VRM) | 85 V - supports transient-tolerant signal clamping in 24–48 V industrial bus interfaces |
| Junction Capacitance (C) | 0.5–2.0 pF at VR = 0 V, f = 1 MHz - minimizes loading on high-Z RF nodes and clock distribution lines |
| Forward Voltage (VF) | 0.76 V min at IF = 10 mA - reduces conduction loss in low-voltage sampling and detection circuits |
| Reverse Current (IR) | Max 0.1 μA at VR = 80 V - preserves signal fidelity in precision analog front-ends and sensor bias networks |
| Average Rectified Current (IO) | 100 mA - sustains continuous duty-cycle operation in compact power management subsystems |

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 |
|---|---|---|---|
| BAV99,115 (Nexperia) | Double diode in SOT-23; trr = 4 ns max; VF = 1.25 V at 100 mA | Higher VF increases conduction loss; dual configuration suits differential clamping but adds layout area | Select when dual-diode topology or legacy SOT-23 footprint required; verify trr margin against 3 ns target |
| 1N4148W-7-F (Diodes Inc.) | SOD-123 package; trr = 4 ns max; VRM = 100 V; C = 4 pF typ. | Higher capacitance degrades RF performance; wider VRM useful only in >85 V systems | Choose for cost-sensitive industrial controls where 4 ns trr and 4 pF C are acceptable trade-offs |
Compared with BAV99,115 and 1N4148W-7-F, the HSM221C-JTL-E delivers superior high-frequency fidelity due to its lower capacitance (0.5 pF vs. ≥4 pF) and tighter trr specification (3.0 ns vs. 4 ns), making it preferred for RF detector and fast snubber roles where signal integrity is critical.

FAQ
What is the maximum reverse recovery time specified for the HSM221C-JTL-E?
The HSM221C-JTL-E has a maximum reverse recovery time (trr) of 3.0 ns, measured under standardized conditions of IF = 10 mA, VR = 6 V, and RL = 50 Ω. This value is guaranteed across the full operating temperature range and is critical for maintaining timing accuracy in high-speed switching applications. The HSM221C-JTL-E achieves this performance via its silicon epitaxial planar construction, which minimizes carrier storage effects.
Does the HSM221C-JTL-E have a pin 1 connection, and what is its function?
No - pin 1 of the HSM221C-JTL-E is designated NC (No Connect) and must remain electrically unconnected in all PCB layouts. The active terminals are pin 2 (Anode) and pin 3 (Cathode), arranged in top-view order 2–1–3. Connecting pin 1 risks introducing parasitic capacitance or thermal imbalance, which could degrade the HSM221C-JTL-E's 3.0 ns trr performance or cause localized overheating.
What is the junction capacitance range of the HSM221C-JTL-E, and how does it affect RF applications?
The HSM221C-JTL-E exhibits junction capacitance ranging from 0.5 pF (typical) to 2.0 pF (maximum) at VR = 0 V and f = 1 MHz. This ultra-low capacitance minimizes signal loading on high-impedance RF nodes, preserving amplitude and phase response in detector, mixer, and antenna switch applications. At 100 MHz, the capacitive reactance remains >800 Ω, ensuring negligible insertion loss compared to alternatives with ≥4 pF C.
Can the HSM221C-JTL-E be used in place of a Schottky diode for high-speed switching?
The HSM221C-JTL-E is not a Schottky diode - it is a silicon epitaxial planar PN junction device. While it matches or exceeds many Schottky diodes in trr (e.g., 3.0 ns vs. 5–10 ns), its forward voltage (0.76–0.97 V) is higher than typical Schottky devices (0.2–0.4 V). Use the HSM221C-JTL-E where ultra-fast recovery and low capacitance outweigh forward-loss sensitivity - such as RF detectors - not low-VF power rectification.
What is the peak forward surge current rating for the HSM221C-JTL-E, and under what conditions is it valid?
The HSM221C-JTL-E supports a non-repetitive peak forward surge current (IFSM) of 4 A, specified for a single pulse duration of 1 μs. This rating applies only to transient overload events such as ESD-induced current spikes or inductive flyback surges. Continuous operation must remain within the average rectified current limit of 100 mA and peak forward current limit of 300 mA to ensure long-term reliability of the HSM221C-JTL-E.
