Product details
Overview
HZS6B1JTA-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 5.5–5.8 V, maximum power dissipation of 400 mW, dynamic resistance of 40 Ω at 5 mA, and junction temperature rating up to 200°C.
For engineers reviewing the HZS6B1JTA-E datasheet, HZS6B1JTA-E pinout, HZS6B1JTA-E application, or HZS6B1JTA-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low leakage current (≤5 µA at VR = 2.0 V), DC-tested performance, 5 mm-pitch auto-insertion compatibility, and thermal stability across industrial ambient ranges.
Technical Context
This discrete Zener diode operates in reverse-bias breakdown mode to maintain stable reference voltage under varying load and line conditions. Its epitaxial planar construction ensures tight VZ distribution and low dynamic impedance (40 Ω), critical for low-noise regulation in feedback loops.
Rated for 400 mW DC power dissipation at 25°C with derating above 25°C, it supports operation from −55°C to +175°C storage and up to 200°C junction temperature-enabling use in compact, thermally constrained PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.5–5.8 V at IZ = 5 mA - defines regulated output voltage range for feedback references |
| Dynamic Resistance (rd) | 40 Ω max at IZ = 5 mA - determines load regulation sensitivity and ripple rejection |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets maximum continuous bias current limit (≈69 mA at 5.8 V) |
| Reverse Current (IR) | ≤5 µA max at VR = 2.0 V - ensures minimal standby power loss in high-impedance bias networks |
| Junction Temperature (Tj) | 200°C max - enables reliable operation in sealed enclosures or near heat-generating components |
| Storage Temperature | −55°C to +175°C - supports automotive under-hood and industrial control cabinet deployment |

Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| 1N4734A (ON Semiconductor) | 6.2 V nominal, ±5% tolerance, 41 Ω rd, 1 W Pd | Higher power rating but looser VZ tolerance; requires layout revision for thermal pad | Prefer when higher power margin is needed and ±5% regulation error is acceptable |
| BZX55C5V6 (Vishay) | 5.6 V nominal, ±5% tolerance, 40 Ω rd, 500 mW Pd, DO-35 package | Same package and rd, but wider VZ spread (5.32–5.88 V) vs. HZS6B1JTA-E's 5.5–5.8 V | Acceptable where tighter VZ binning is not required and cost optimization is prioritized |
Compared with 1N4734A and BZX55C5V6, HZS6B1JTA-E offers superior VZ binning (±0.15 V vs. ±0.3 V typical), enabling higher-accuracy regulation without post-assembly calibration-critical for space-constrained industrial and medical designs.

FAQ
What is the exact zener voltage range specified for HZS6B1JTA-E?
HZS6B1JTA-E has a guaranteed zener voltage range of 5.5 V to 5.8 V when tested at IZ = 5 mA and Ta = 25°C. This narrow ±0.15 V tolerance supports high-accuracy voltage references without external trimming, distinguishing it from broader-bin alternatives like BZX55C5V6.
Is HZS6B1JTA-E suitable for surface-mount assembly?
No-HZS6B1JTA-E uses a DO-35 glass axial package with 5 mm lead pitch, optimized for through-hole automatic insertion. It is not a surface-mount device; no SMD variant (e.g., SOD-123 or SOD-323) exists for this specific grade. For SMT designs, consider ROHM's UDZS series Zeners instead.
What is the maximum reverse leakage current for HZS6B1JTA-E?
HZS6B1JTA-E specifies a maximum reverse leakage current (IR) of 5 µA at VR = 2.0 V and Ta = 25°C. This low leakage supports energy-efficient operation in battery-backed or always-on circuits where standby current must remain below 10 µA.
Does HZS6B1JTA-E require derating above 25°C ambient?
Yes-HZS6B1JTA-E's 400 mW power dissipation rating applies only at Ta = 25°C. Derating is linear at 3.2 mW/°C above 25°C, reaching zero dissipation at approximately 150°C ambient. Full thermal design must account for PCB copper area and airflow per ROHM's publication value curves.
Can HZS6B1JTA-E replace older Zener diodes like 1N4734A in existing designs?
HZS6B1JTA-E is not a direct replacement for 1N4734A due to different nominal voltages (5.5–5.8 V vs. 6.2 V) and tighter tolerance. Swapping requires verification of circuit headroom and regulation setpoint. Use only after confirming that 5.6 V reference meets system-level accuracy requirements.
