Product details
Overview
HZS2C2JTA-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power stabilized power supplies, with a nominal zener voltage of 2.4 V (min 2.4 V / max 2.6 V), 400 mW power dissipation, and dynamic resistance of 100 Ω at 5 mA test current. It features low leakage, low zener impedance, and is optimized for 5 mm-pitch high-speed automatic insertion in consumer and industrial PCB assembly.
For engineers reviewing the HZS2C2JTA-E datasheet, HZS2C2JTA-E pinout, HZS2C2JTA-E application, or HZS2C2JTA-E equivalent, this device serves as a compact, cost-effective voltage reference for biasing, overvoltage protection, and feedback loop stabilization in DC-DC converters, sensor signal conditioning, and microcontroller reset circuits where ±5% tolerance and thermal stability down to −55°C are required.
Technical Context
The HZS2C2JTA-E operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse current above its specified zener breakdown threshold. Its planar junction construction ensures consistent parameter distribution and low temperature coefficient drift across production lots.
Rated for 200°C junction temperature and −55°C to +175°C storage range, it supports operation in thermally demanding environments without derating below 25°C ambient. The device exhibits 100 Ω dynamic resistance at 5 mA, enabling predictable regulation under varying load conditions typical in low-current analog and digital reference applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.4 V min / 2.6 V max at 5 mA - defines precise regulation window for 2.5 V nominal rail referencing |
| Power Dissipation (Pd) | 400 mW - supports continuous operation up to ~166 mA at 2.4 V without heatsinking |
| Dynamic Resistance (rd) | 100 Ω at IZ = 5 mA - ensures <±25 mV output shift per ±2.5 mA load variation |
| Reverse Current (IR) | Max 25 µA at VR = 0.5 V - guarantees minimal standby power loss in always-on reference paths |
| Junction Temperature (Tj) | 200°C - allows reliable operation in enclosed enclosures or near heat-generating components |
| Package Type | MHD (glass-passivated DO-35 equivalent) - enables automated placement and solder reflow compatibility |
Pinout & Package
Package: MHD - miniature hermetically sealed glass axial package (2.0 mm diameter × 4.0 mm length), JEITA code GRZZ0002ZC-A, mass 0.084 g, compatible with 5 mm pitch insertion equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener terminal (anode referenced) | Connected to regulated voltage node; polarity critical for correct breakdown conduction |
| 2 (Anode) | Reference ground/reference return | Typically tied to system GND or lower-voltage rail; reverse-biased configuration requires anode at lower potential |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Microcontroller Reset Circuit | Sensor Signal Conditioning |
|---|---|
Use Scenario: Providing clean, stable reset threshold for 3.3 V microcontrollers during power-up and brown-out events. IC Role / Device Role / Timing Role: Shunt voltage reference defining logic-high reset release point. Use Value: 2.4–2.6 V range aligns with common 3.3 V MCU reset IC thresholds, minimizing external component count. |
Use Scenario: Biasing bridge sensors or op-amp input stages requiring low-drift reference voltage. IC Role / Device Role / Timing Role: Precision DC reference source for excitation or offset calibration. Use Value: Low 25 µA leakage avoids loading sensitive high-impedance sensor nodes at 25°C. |
| DC-DC Converter Feedback | Overvoltage Protection Clamp |
Use Scenario: Setting output voltage in adjustable buck/boost regulators via resistor divider feedback. IC Role / Device Role / Timing Role: Stable reference node for error amplifier comparison. Use Value: 100 Ω rd limits feedback error to <±25 mV over 5 mA load swing, improving output accuracy. |
Use Scenario: Clamping transient surges on 3.3 V or 5 V rails to prevent IC damage. IC Role / Device Role / Timing Role: Fast-acting shunt limiter activated above 2.6 V. Use Value: 400 mW Pd sustains 150 ms surge at 160 mA, sufficient for ESD and inductive kick suppression. |
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 |
|---|---|---|---|
| BZX55C2V4 (ON Semiconductor) | Same 2.4 V nominal, but 500 mW Pd, 120 Ω rd, DO-35 package | Higher power handling suits higher-energy clamping; slightly higher impedance affects precision feedback | Select when >400 mW surge margin is required and board space permits DO-35 footprint |
| MMBZ5222BS (Diodes Inc.) | 2.4 V nominal, SOT-23 package, 200 mW Pd, 100 Ω rd, 10 µA IR | Surface-mount form factor saves space; lower power rating limits clamping energy | Choose for space-constrained PCBs where 200 mW regulation suffices and reflow compatibility is mandatory |
Compared with BZX55C2V4 and MMBZ5222BS, the HZS2C2JTA-E offers optimal balance of axial-package manufacturability, 400 mW robustness, and 100 Ω regulation fidelity-making it preferred for through-hole production lines targeting cost-sensitive industrial and consumer power management.

FAQ
What is the exact zener voltage range for HZS2C2JTA-E at 5 mA test current?
The HZS2C2JTA-E has a guaranteed zener voltage range of 2.4 V minimum to 2.6 V maximum when tested at 5 mA reverse current and 25°C ambient temperature, corresponding to Grade C2 within the HZS2 family as defined in Renesas document REJ03G0184-0500 Rev.5.00.
Does HZS2C2JTA-E support automated PCB assembly?
Yes, HZS2C2JTA-E uses the MHD package with 5 mm pitch spacing and axial lead configuration, explicitly qualified for high-speed automatic insertion equipment per Renesas specification-enabling direct integration into legacy through-hole production lines without adapter tooling.
What is the maximum allowable junction temperature for continuous operation of HZS2C2JTA-E?
The HZS2C2JTA-E is rated for a maximum junction temperature of 200°C, allowing uninterrupted operation in thermally constrained environments such as sealed enclosures or proximity to power MOSFETs, provided power dissipation remains within the 400 mW limit and thermal path design accounts for ambient rise.
How does the dynamic resistance of HZS2C2JTA-E affect voltage regulation accuracy?
With a dynamic resistance of 100 Ω at 5 mA, the HZS2C2JTA-E introduces ≤±25 mV output deviation for every ±2.5 mA change in zener current-making it suitable for applications like feedback networks and reset circuits where sub-50 mV regulation stability is required under expected load variance.
Is HZS2C2JTA-E compliant with RoHS and lead-free soldering requirements?
Yes, HZS2C2JTA-E meets EU RoHS Directive requirements and is compatible with standard lead-free reflow profiles, as confirmed by Renesas' environmental compliance documentation and material declarations associated with the HZS Series and MHD package construction.
