Product details
Overview
HZS6.2NB2-1TA-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 6.2 V (min 5.6 V, max 5.9 V), dynamic resistance of 40 Ω at 5 mA, maximum power dissipation of 400 mW, and junction temperature rating up to 200°C - used in low-power reference and biasing circuits.
For engineers reviewing the HZS6.2NB2-1TA-E datasheet, HZS6.2NB2-1TA-E pinout, HZS6.2NB2-1TA-E application, or HZS6.2NB2-1TA-E equivalent, key selection criteria include zener voltage tolerance (±5% grade B2), low dynamic impedance for stable regulation under load variation, DC-tested characteristics, and compatibility with 5 mm-pitch automated insertion in compact PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage stabilization across its specified test current range (IZ = 5 mA). Its epitaxial planar construction ensures low leakage current (IR ≤ 5 µA at VR = 2.0 V) and consistent thermal performance up to 200°C junction temperature.
The device exhibits a negative temperature coefficient near 6.2 V (≈ −2.0 mV/°C per Fig.2), making it suitable for temperature-compensated references when paired with positive-TC components. It is rated for continuous DC operation only, not AC or pulse conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V min to 5.9 V max at IZ = 5 mA - defines regulated output voltage window under nominal bias |
| Dynamic Resistance (rd) | 40 Ω max at IZ = 5 mA - determines output voltage stability against load current changes |
| Reverse Current (IR) | ≤ 5 µA at VR = 2.0 V - ensures minimal standby power loss in high-impedance bias networks |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets upper limit for continuous DC power handling on standard FR-4 PCB |
| Junction Temperature (Tj) | −55°C to +200°C - enables use in automotive under-hood and industrial control environments |
| Package Type | DO-35 (glass axial) - standardized through-hole package compatible with 5 mm pitch auto-insertion equipment |
Pinout & Package
Package: DO-35 glass axial leaded package with cathode band marking; leads are tinned copper, 0.45–0.55 mm diameter, 25 mm minimum length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to higher potential node; reverse-biased terminal where zener breakdown occurs |
| 2 (Non-banded End) | Anode | Connected to lower potential node or ground; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 40 Ω max ensures < ±10 mV output shift per 0.4 mA load change - critical for precision analog references |
| Wide zener voltage spectrum | Graded B2 variant within 6.2 V family provides ±5% tolerance - balances cost and accuracy for non-critical regulation |
| High junction temperature rating | 200°C Tj allows operation in sealed enclosures or near heat-generating components without derating |
| Automated insertion compatibility | 5 mm pitch lead spacing supports high-throughput placement in legacy and modern SMT hybrid assembly lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4735A | Zener voltage 6.2 V (±5%), rd = 5 Ω max, Pd = 1 W - lower impedance but higher power and larger DO-41 package | Requires PCB pad redesign; better for high-current reference but over-specified for low-power biasing | Select when tighter regulation (< 0.5% line/load regulation) is required and board space permits larger footprint |
| BZX55C6V2 | Zener voltage 6.2 V (±5%), rd = 60 Ω max, Pd = 500 mW - slightly higher impedance, same DO-35 package | Compatible drop-in replacement with identical mounting; marginally less stable under dynamic load | Preferred for cost-sensitive designs where 60 Ω vs. 40 Ω rd has negligible impact on system accuracy |
Compared with HZS6.2NB2-1TA-E, the 1N4735A offers superior regulation at higher power cost and size, while the BZX55C6V2 matches form-factor and grading but trades 50% higher dynamic resistance for broader vendor availability and lower unit price.

FAQ
What is the exact zener voltage range for HZS6.2NB2-1TA-E?
HZS6.2NB2-1TA-E has a guaranteed zener voltage range of 5.6 V to 5.9 V at test current IZ = 5 mA, corresponding to Grade B2 in the HZS6 family. This ±5% tolerance is verified per ROHM's ADE-208-120A(Z) specification document and applies under DC conditions only.
Is HZS6.2NB2-1TA-E suitable for surface-mount assembly?
No - HZS6.2NB2-1TA-E uses a DO-35 glass axial package with radial leads intended for through-hole mounting and 5 mm-pitch automatic insertion. It is not compatible with reflow soldering or pick-and-place SMT processes due to thermal mass and lead geometry.
What is the maximum reverse leakage current for HZS6.2NB2-1TA-E?
The maximum reverse leakage current for HZS6.2NB2-1TA-E is 5 µA at VR = 2.0 V and Ta = 25°C. This value is confirmed in the Electrical Characteristics table for HZS6 B2 grade and reflects low standby power consumption ideal for battery-backed circuits.
Does HZS6.2NB2-1TA-E support AC signal clamping?
No - the datasheet specifies DC testing only (Note 1), and HZS6.2NB2-1TA-E is characterized exclusively for steady-state reverse-bias DC operation. Its dynamic resistance and thermal response are not validated for AC or repetitive pulse conditions.
Can HZS6.2NB2-1TA-E replace a 6.2 V Zener in an existing DO-35 footprint?
Yes - HZS6.2NB2-1TA-E uses the industry-standard DO-35 package with 5 mm lead pitch and identical mechanical dimensions to other DO-35 Zeners, enabling direct physical replacement in legacy designs without PCB modification.
