Product details
Overview
HZS2C2JRX from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power stabilized power supplies. It delivers a nominal zener voltage of 2.4 V (min 2.4 V, max 2.6 V) at 5 mA test current, with dynamic resistance of 100 Ω, maximum power dissipation of 400 mW, and operates within −55°C to +175°C storage temperature range.
For engineers reviewing the HZS2C2JRX datasheet, HZS2C2JRX pinout, HZS2C2JRX application, or HZS2C2JRX equivalent, key selection criteria include its 2.4 V zener voltage tolerance, low leakage performance, suitability for 5 mm-pitch automated insertion, and use in compact DC biasing and reference circuits where thermal stability and low impedance are critical.
Technical Context
The HZS2C2JRX belongs to the HZS Series, a family of general-purpose silicon planar Zener diodes optimized for stable voltage reference and overvoltage protection in low-current applications. Its construction uses planar diffusion technology to achieve consistent breakdown characteristics and low zener impedance.
It operates under DC test conditions with specified reverse current ≤25 µA at VR = 0.5 V, junction temperature up to 200°C, and is rated for standard industrial applications per Renesas quality grading - not intended for automotive, medical, or safety-critical systems without explicit approval.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.4 V min / 2.6 V max at IZ = 5 mA - defines tight regulation window for 2.5 V nominal bias rails |
| Dynamic Resistance (rd) | 100 Ω max at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact PCB layouts with moderate airflow |
| Reverse Current (IR) | ≤25 µA at VR = 0.5 V - enables low quiescent current design in battery-backed or energy-sensitive circuits |
| Junction Temperature (Tj) | 200°C max - allows reliable operation in high-ambient industrial environments with proper thermal relief |
| Storage Temperature | −55°C to +175°C - compatible with reflow soldering and extended environmental deployment |
Pinout & Package
Package: MHD (Mini-High-Density) - axial-lead, glass-passivated, 2.0 mm diameter body, 26.0 mm length, 5 mm pitch spacing, compatible with high-speed automatic insertion equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown terminal | Connected to regulated output node; polarity marking (lake blue band) identifies cathode for correct orientation in series-shunt regulation |
| 2 (Anode) | Reference ground return | Provides low-impedance path to circuit common; reverse-biased configuration requires anode at lower potential than cathode |
Key Features
| Feature | Design Value |
|---|---|
| Low zener impedance | 100 Ω max ensures <1% output deviation across ±1 mA load current change in reference designs |
| Wide zener voltage spectrum | 1.6–38 V family coverage enables single-source sourcing for multi-rail systems using HZS2C2JRX as 2.4 V node |
| High-speed insertion compatibility | 5 mm pitch and MHD mechanical dimensions support automated assembly without lead forming or special tooling |
| Stable temperature coefficient | γZ ≈ −0.04 %/°C near 2.4 V (inferred from Fig.2 trend) - minimizes drift in ambient-temperature-varying environments |
Applications
| Industrial Sensor Biasing | Microcontroller Reset Reference |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4730A (ON Semiconductor) | Zener voltage 3.9 V, Pd = 1 W, DO-41 package - higher power but incompatible voltage grade | Not suitable for 2.4 V biasing; requires redesign of resistor network and layout | Select only if upgrading to higher-voltage reference with thermal margin increase |
| BZX55C2V4 (Vishay) | Zener voltage 2.4 V ±5%, Pd = 500 mW, DO-35 package - same VZ grade but larger footprint and 0.5 mm lead spacing | Compatible functionally but requires PCB pad revision due to DO-35 vs. MHD mechanical mismatch | Use when legacy DO-35 tooling exists and 5 mm pitch automation is not required |
Compared with 1N4730A and BZX55C2V4, the HZS2C2JRX offers tighter 2.4 V tolerance (±0.1 V), optimized 5 mm pitch for modern SMT-compatible insertion, and lower thermal resistance in the MHD package - making it preferable for space-constrained, high-volume industrial control modules.

FAQ
What is the exact zener voltage range specified for HZS2C2JRX?
The HZS2C2JRX has a guaranteed zener voltage range of 2.4 V minimum to 2.6 V maximum when tested at IZ = 5 mA and Ta = 25°C. This 0.2 V tolerance band ensures predictable regulation behavior in precision low-voltage reference applications, and is confirmed in the "Electrical Characteristics" table on page 2 of Renesas document REJ03G0184-0500 Rev.5.00.
Is HZS2C2JRX suitable for automotive applications?
No, the HZS2C2JRX is classified as a "Standard" quality grade device per Renesas documentation and is explicitly intended for computers, office equipment, communications gear, and industrial robots - not for transportation systems including automobiles. Using HZS2C2JRX in automotive contexts requires formal written consent from Renesas Electronics and is not supported under standard product warranties.
What package type does HZS2C2JRX use, and is it lead-free?
HZS2C2JRX uses the MHD (Mini-High-Density) axial-leaded package with JEITA code GRZZ0002ZC-A, featuring a 2.0 mm diameter glass body and 26 mm length. Per Renesas environmental compliance statements in the document, the device meets EU RoHS Directive requirements and is lead-free, with no exemptions applied to its termination finish or internal structure.
How does the dynamic resistance of HZS2C2JRX affect its performance in voltage reference circuits?
The HZS2C2JRX specifies dynamic resistance rd ≤100 Ω at IZ = 5 mA, meaning its output voltage varies less than 100 mV per 1 mA change in zener current. This low impedance directly improves regulation accuracy in low-noise reference designs, especially when paired with high-value series resistors that limit current variation under input voltage fluctuations - a key advantage over higher-rd alternatives like older 1N47xx series diodes.
Can HZS2C2JRX be used in place of HZS2B2?
No - HZS2B2 has a zener voltage range of 2.0 V to 2.2 V, while HZS2C2JRX is rated 2.4 V to 2.6 V. Although both share the same MHD package and 400 mW rating, their voltage grades are non-interchangeable without circuit recalculations. Substituting HZS2C2JRX for HZS2B2 would raise the regulated node by ~0.3 V, potentially violating downstream IC input voltage limits or bias point requirements.
