Product details
Overview
HZS6C2TA-E 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 6.1–6.4 V at 5 mA test current, with dynamic resistance of 2.0 Ω, maximum power dissipation of 400 mW, and operates across −55°C to +175°C storage temperature range. It is used in voltage reference circuits for industrial sensor signal conditioning.
For engineers reviewing the HZS6C2TA-E datasheet, HZS6C2TA-E pinout, HZS6C2TA-E application, or HZS6C2TA-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low dynamic impedance, DC-tested characteristics, 5 mm-pitch auto-insertion compatibility, and MHD package thermal performance in ambient temperatures up to 70°C.
Technical Context
The HZS6C2TA-E employs a silicon planar junction structure optimized for stable reverse-bias operation. Its zener voltage is specified at 5 mA DC test current, with reverse current limited to ≤5 µA at VR = 1.0 V, ensuring low leakage in standby modes.
Thermal design is supported by a maximum junction temperature of 200°C and derated power dissipation above 25°C ambient-e.g., ~250 mW at 70°C per Fig.3. The device exhibits a negative zener voltage temperature coefficient near 6.2 V, typical for this voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.1 V min / 6.4 V max at IZ = 5 mA - defines tight regulation window for 6.2 V nominal reference |
| Dynamic Resistance (rd) | 2.0 Ω max at IZ = 5 mA - ensures minimal output voltage variation under load transients |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact PCB layouts without forced cooling |
| Reverse Current (IR) | ≤5 µA max at VR = 1.0 V - guarantees low quiescent current in battery-backed or energy-sensitive circuits |
| Junction Temperature (Tj) | 200°C max - enables reliable operation in high-temperature industrial environments (e.g., motor control enclosures) |
| Package Type | MHD (JEITA GRZZ0002ZC-A) - standardized 5 mm-pitch leaded package compatible with high-speed automatic insertion equipment |
Pinout & Package
Package: MHD (JEITA code GRZZ0002ZC-A), axial-leaded, epoxy-molded, 2.0 mm diameter body, 26.0 mm lead length, 5 mm pitch. Mass: 0.084 g (typ).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener cathode terminal | Connected to regulated positive rail; polarity marking (lake blue band) identifies this end for correct PCB orientation |
| 2 (Anode) | Zener anode terminal | Connected to circuit ground or lower potential node; completes reverse-bias path for voltage clamping/reference |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 2.0 Ω max ensures <12 mV output shift for ±10 mA load change at 5 mA bias - critical for ADC reference stability |
| Wide zener voltage spectrum | Part of HZS Series covering 1.6–38 V - allows single-source procurement across multiple voltage rails in same design family |
| High-temperature capability | Rated to 200°C junction temperature - supports use in under-hood automotive modules or enclosed industrial drives |
| Automated assembly compatibility | MHD package with 5 mm pitch meets IPC-J-STD-020 insertion standards - reduces SMT line conversion cost vs. surface-mount alternatives |
Applications
| Industrial Sensor Signal Conditioning | Programmable Logic Controller (PLC) Analog Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4735A (ON Semiconductor) | Zener voltage 6.2 V ±5% (6.0–6.4 V), rd = 5.0 Ω, Pd = 1.0 W, DO-41 package | Higher power rating but looser voltage tolerance and higher impedance - suitable where headroom exists but precision is secondary | Select when board space permits larger DO-41 footprint and thermal margin exceeds 400 mW requirement |
| BZX55C6V2 (Nexperia) | Zener voltage 6.2 V ±5%, rd = 10 Ω, Pd = 500 mW, DO-35 package | Higher dynamic resistance degrades regulation under fast load steps; wider tolerance increases calibration burden | Prefer only if existing BOM uses BZX55 series and minor performance trade-offs are acceptable |
Compared with 1N4735A and BZX55C6V2, the HZS6C2TA-E offers tighter voltage tolerance (±0.15 V vs. ±0.3 V), lower dynamic resistance (2.0 Ω vs. ≥5.0 Ω), and MHD package compatibility with high-speed insertion lines-making it optimal for volume-manufactured industrial electronics requiring repeatable 6.2 V references.

FAQ
What is the exact zener voltage range for HZS6C2TA-E at 5 mA?
The HZS6C2TA-E has a guaranteed zener voltage range of 6.1 V minimum to 6.4 V maximum when tested at IZ = 5 mA DC, per Renesas datasheet REJ03G0184-0500 Rev.5.00. This 0.3 V span reflects Grade C2 tolerance within the HZS6 family and is confirmed by production binning data-not a typical or average value.
Is HZS6C2TA-E suitable for automotive applications?
HZS6C2TA-E is rated for "Standard" quality grade per Renesas documentation, intended for industrial, office, and communications equipment-not automotive-grade systems. It lacks AEC-Q200 qualification, and Renesas explicitly restricts its use in transportation equipment without prior written consent. For automotive designs, consult Renesas' dedicated automotive Zener portfolio.
What does the "TA-E" suffix indicate in HZS6C2TA-E?
The "TA-E" suffix in HZS6C2TA-E denotes tape-and-reel packaging per JEDEC standard J-STD-033, with embossed carrier tape (E), 2000 units per reel, and RoHS-compliant lead finish. This differs from bulk or ammo-pack variants and ensures compatibility with pick-and-place and high-speed insertion equipment.
How does the dynamic resistance of HZS6C2TA-E affect voltage regulation accuracy?
The HZS6C2TA-E's dynamic resistance of 2.0 Ω max directly determines output voltage deviation under load changes: a 10 mA load step causes ≤20 mV shift in regulated voltage. This enables sub-0.1% regulation stability in precision analog circuits-critical for 12-bit+ data acquisition systems where reference drift impacts measurement fidelity.
Can HZS6C2TA-E replace HZS6B2 in an existing design?
No-HZS6C2TA-E and HZS6B2 are distinct variants: HZS6B2 specifies 6.7–7.0 V zener voltage, while HZS6C2TA-E is 6.1–6.4 V. Substituting them would shift reference voltage by ~0.6 V, likely violating system-level tolerances. Always verify zener voltage grade (B2 vs. C2) and suffix (TA-E vs. others) before replacement.
