Product details
Overview
HZS7C2LTA-E from Renesas Electronics is a silicon planar Zener diode engineered for low-noise voltage regulation in precision analog circuits, featuring a nominal zener voltage of 7.5 V (min 7.3 V, max 7.7 V), dynamic resistance of 60 Ω at 3.5 mA, and maximum power dissipation of 400 mW. It operates with low leakage current (<1 μA at 2.0 V reverse bias) and is qualified for standard-grade industrial applications including stabilized power supplies and reference voltage sources.
For engineers reviewing the HZS7C2LTA-E datasheet, HZS7C2LTA-E pinout, HZS7C2LTA-E application, or HZS7C2LTA-E equivalent, key selection criteria include zener voltage tolerance (±0.2 V), temperature coefficient behavior near 7.5 V, noise performance relative to legacy HZ series, and compatibility with 5 mm-pitch automated insertion equipment.
Technical Context
This device uses a planar diffusion process to achieve stable zener breakdown with reduced flicker noise-approximately 1/3 to 1/10 that of the older HZ series. Its low dynamic impedance (60 Ω) ensures tight regulation under varying load conditions at IZ = 3.5 mA.
The HZS7C2LTA-E exhibits a negative temperature coefficient near 7.5 V (≈ −0.04 %/°C or −3.0 mV/°C), enabling predictable drift compensation in reference designs. It is rated for junction temperatures up to 200°C and storage from −55°C to +175°C, supporting operation in demanding ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.3 V min / 7.7 V max at IZ = 0.5 mA - defines regulation window for precision 7.5 V references. |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 3.5 mA - enables <10 mV output variation per 0.6 mA load change. |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact PCB layouts with minimal heatsinking. |
| Reverse Leakage (IR) | 1 μA max at VR = 2.0 V - minimizes error current in high-impedance bias networks. |
| Junction Temperature (Tj) | 200°C max - allows reliable operation in thermally constrained enclosures or near heat-generating components. |
| Noise Performance | ~1/3–1/10 of HZ-series diodes - critical for audio preamps, sensor signal conditioning, and ADC reference stability. |
Pinout & Package
Package: MHD (JEITA code GRZZ0002ZC-A), axial-leaded, 2.0 mm diameter body, 26.0 mm length, 5 mm pitch compatible, mass ≈ 0.084 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown terminal | Connected to regulated positive rail; polarity must be observed to avoid forward conduction. |
| 2 (Anode) | Reference ground node | Serves as circuit common; reverse-biased configuration requires anode at lower potential than cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener structure | Planar silicon construction reduces flicker noise by factor of 3–10 vs. HZ series-essential for low-drift analog references. |
| Stable voltage regulation | ±0.2 V tolerance at 7.5 V with 60 Ω dynamic impedance-supports ±0.5% output accuracy in untrimmed supplies. |
| High thermal robustness | 200°C max junction temperature and −55°C to +175°C storage range-enables use in automotive under-hood or industrial control cabinets. |
| Automated assembly compatibility | 5 mm pitch axial lead spacing and standardized MHD package-directly supports high-speed pick-and-place and wave soldering. |

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 |
|---|---|---|---|
| BZX84-C7V5 (Nexperia) | 300 mW Pd, 80 Ω rd, ±5% VZ tolerance (7.13–7.88 V), SOT-23 package | Surface-mount only; higher dynamic impedance limits regulation accuracy in precision analog rails | Preferred for space-constrained PCBs where 7.5 V ±5% is acceptable and noise is secondary |
| 1N4733A (ON Semiconductor) | 1 W Pd, 7 Ω rd, ±5% VZ (7.13–7.88 V), DO-41 package, higher noise than HZS-L | Higher power handling but significantly higher noise and looser voltage tolerance | Selected when thermal margin >1 W is required and low-noise performance is not critical |
Compared with BZX84-C7V5 and 1N4733A, the HZS7C2LTA-E delivers tighter voltage tolerance (±0.2 V vs. ±5%), lower noise (3–10×), and optimized dynamic impedance (60 Ω) for precision analog reference use-making it uniquely suited for metrology, audio, and medical sensor applications where stability and spectral purity are design-critical.

FAQ
What is the zener voltage tolerance of HZS7C2LTA-E?
The HZS7C2LTA-E has a specified zener voltage range of 7.3 V minimum to 7.7 V maximum at 0.5 mA test current, yielding a ±0.2 V absolute tolerance centered on 7.5 V. This tight tolerance supports high-accuracy voltage references without external trimming and is confirmed in the Renesas REJ03G0166-0300 datasheet, page 2.
Does HZS7C2LTA-E support automated PCB assembly?
Yes, the HZS7C2LTA-E uses the MHD axial package with 5 mm lead pitch, explicitly designed for compatibility with high-speed automatic insertion equipment. Its standardized dimensions (2.0 mm body diameter, 26.0 mm length) and JEITA code GRZZ0002ZC-A ensure reliable feeding and placement in industrial SMT and through-hole lines.
How does the noise performance of HZS7C2LTA-E compare to standard Zener diodes?
The HZS7C2LTA-E achieves approximately 1/3 to 1/10 the noise level of the legacy HZ series due to its silicon planar construction and optimized doping profile. This low-noise characteristic is validated in Renesas' characterization data and makes HZS7C2LTA-E especially valuable in audio preamplifiers, sensor signal chains, and high-resolution ADC reference designs.
What is the maximum power dissipation rating for HZS7C2LTA-E?
The HZS7C2LTA-E is rated for 400 mW maximum power dissipation at 25°C ambient temperature. Derating follows the curve in Figure 3 of the REJ03G0166-0300 datasheet, reaching ~200 mW at 70°C ambient-enabling reliable operation in enclosed industrial enclosures without forced airflow.
Is HZS7C2LTA-E suitable for automotive applications?
No-HZS7C2LTA-E is classified as a Standard-grade Renesas product intended for computers, office equipment, industrial robots, and communications gear. It is not qualified for automotive (AEC-Q101) or safety-critical applications. For automotive use, consult Renesas' High Quality-grade Zener offerings or alternative qualified parts.
