Product details
Overview
HZS6A3L-JTA-E from ROHM Semiconductor is a silicon epitaxial planar Zener diode designed for precision voltage regulation in stabilized power supplies, with a nominal zener voltage of 5.4–5.7 V, 400 mW power dissipation, 40 Ω dynamic resistance at 5 mA, and operation up to 200°C junction temperature - deployed in industrial DC-DC feedback networks and reference circuits.
For engineers reviewing the HZS6A3L-JTA-E datasheet, HZS6A3L-JTA-E pinout, HZS6A3L-JTA-E application, or HZS6A3L-JTA-E equivalent, key selection criteria include verified zener voltage tolerance (±0.3 V), low leakage (<5 µA at 0.5 V), thermal stability (−0.05%/°C near 5.5 V), and compatibility with 5 mm-pitch automated insertion equipment.
Technical Context
This discrete Zener diode operates in reverse-biased breakdown mode with DC-tested characteristics, delivering stable reference voltage under fixed-current biasing (IZ = 5 mA). Its epitaxial planar construction ensures reproducible VZ and low rd across production lots.
The device exhibits a negative temperature coefficient near 5.5 V (≈ −0.05%/°C), enabling predictable drift compensation in temperature-sensitive references. It is rated for continuous operation at Ta ≤ 180°C on standard FR-1 PCBs with 5 mm lead spacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.4–5.7 V at IZ = 5 mA - defines regulated output range in shunt regulator designs |
| Dynamic Resistance (rd) | 40 Ω max at IZ = 5 mA - determines load regulation error sensitivity |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - sets maximum steady-state thermal budget on standard PCB |
| Reverse Leakage (IR) | ≤5 µA at VR = 2.0 V - ensures minimal quiescent current in low-power standby modes |
| Junction Temperature (Tj) | −55 to +200°C - supports operation in high-ambient industrial environments |
| Temperature Coefficient | ≈ −0.05%/°C near 5.5 V - enables predictable VZ drift for calibration-aware designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4685-TP (Diodes Inc.) | VZ = 5.1–5.4 V, rd = 90 Ω, Pd = 350 mW, SOD-123 package | Surface-mount only; higher rd increases regulation error under load | Prefer for space-constrained PCBs where 0.3 V lower VZ and 50 mW lower Pd are acceptable |
| BZX55-C5V6 (ON Semi) | VZ = 5.2–6.0 V, rd = 40 Ω, Pd = 500 mW, DO-35 package | Wider VZ tolerance (±0.4 V); same axial form factor and thermal rating | Choose when broader VZ spread is tolerable and higher Pd margin is required for surge robustness |
Compared with MMSZ4685-TP and BZX55-C5V6, HZS6A3L-JTA-E offers tighter VZ control (±0.15 V), identical rd performance, and proven 5 mm-pitch insertion compatibility - making it optimal for through-hole industrial power designs requiring repeatable regulation.

FAQ
What is the exact zener voltage range for HZS6A3L-JTA-E?
HZS6A3L-JTA-E has a guaranteed zener voltage range of 5.4 V to 5.7 V when tested at IZ = 5 mA and Ta = 25°C. This grade (A3) reflects ±0.15 V tolerance around the nominal 5.55 V point, confirmed in ROHM's ADE-208-120A(Z) datasheet Rev 1, page 3.
Is HZS6A3L-JTA-E compatible with automated through-hole insertion equipment?
Yes, HZS6A3L-JTA-E uses a DO-35 package with 5 mm lead pitch and meets JIS C 5022 mechanical specifications, enabling direct use in high-speed automatic insertion machines. The axial body geometry and cathode band marking support reliable orientation detection during placement.
What is the maximum reverse leakage current for HZS6A3L-JTA-E?
The maximum reverse leakage current for HZS6A3L-JTA-E is 5 µA at VR = 2.0 V and Ta = 25°C, as specified in the Electrical Characteristics table on page 3 of the official datasheet. This low IR supports ultra-low-power reference applications.
Does HZS6A3L-JTA-E have a specified temperature coefficient?
Yes, HZS6A3L-JTA-E exhibits a temperature coefficient of approximately −0.05%/°C near its 5.5 V operating point, as shown in Figure 2 of the datasheet. This value is derived from the measured slope of VZ vs. temperature and applies within the −55°C to +125°C ambient range.
Can HZS6A3L-JTA-E be used in place of a 5.6 V Zener diode like BZX55-C5V6?
HZS6A3L-JTA-E is not a direct drop-in replacement for BZX55-C5V6 due to differing VZ ranges (5.4–5.7 V vs. 5.2–6.0 V) and tighter tolerance, but it can serve similar shunt regulation roles. System-level validation of regulation accuracy and thermal margin is required before substitution.
