Product details
Overview
HZS13NB3TA-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 13.03–13.62 V at 5 mA test current, with dynamic resistance of 10 Ω, maximum power dissipation of 400 mW, and junction temperature rating up to 200°C - enabling use in compact industrial and consumer power rails.
For engineers reviewing the HZS13NB3TA-E datasheet, HZS13NB3TA-E pinout, HZS13NB3TA-E application, or HZS13NB3TA-E equivalent, this page provides verified electrical specifications, package dimensions, thermal derating behavior, real-world stabilization use cases, and two confirmed alternative Zener diodes with documented voltage and impedance differences.
Technical Context
The HZS13NB3TA-E operates as a two-terminal shunt regulator, maintaining stable output voltage across variable load and input conditions via controlled reverse-biased breakdown. Its low leakage (≤0.2 μA at VR = 10 V) and tight zener voltage tolerance (B3 grade: ±4.5% typical) support accurate reference generation in feedback loops.
Thermal performance is defined by a junction-to-ambient thermal resistance of ~375 K/W on standard FR-1 PCB (100 × 180 × 1.6 mm), with power derating beginning at 50°C ambient. The device exhibits a positive zener voltage temperature coefficient (~+5.5 mV/°C near 13 V), requiring compensation in high-stability references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.03–13.62 V at IZ = 5 mA - defines regulated output voltage window under nominal bias. |
| Dynamic Resistance (rd) | 10 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity. |
| Reverse Leakage (IR) | ≤0.2 μA at VR = 10 V - ensures minimal quiescent current in standby or low-power modes. |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets absolute thermal limit before derating applies. |
| Junction Temperature (Tj) | −55 to +200°C - enables operation in extended-temperature industrial environments. |
| Package Type | MHD (JEITA GRZZ0002ZC-A) - axial-lead, 5 mm pitch, compatible with high-speed automatic insertion. |
| Zener Tempco (γZ) | +5.5 mV/°C typical - quantifies voltage drift per degree, critical for temperature-compensated designs. |
Pinout & Package
MHD package: axial-leaded, cylindrical glass body (φD = 2.0 mm, L = 26.0 mm), cathode marked by black band. Leads are tinned copper, suitable for wave soldering and automated placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Reverse-biased terminal | Connected to regulated output node; carries full load current during regulation. |
| 2 (Anode) | Reference/ground terminal | Typically tied to system ground or lower-potential rail; establishes bias reference point. |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 10 Ω max ensures <13 mV output variation per 1 mA load change at 5 mA bias. |
| B3-grade voltage tolerance | ±4.5% (13.03–13.62 V) enables tighter regulation than general-purpose Zeners (e.g., B1/B2 grades). |
| 400 mW power rating | Supports ≥30 mA regulation current at 13 V without external heatsinking on standard PCB. |
| High junction temperature rating | 200°C Tj allows reliable operation in enclosed or thermally constrained enclosures. |
| 5 mm pitch compatibility | Enables direct integration into legacy through-hole assembly lines without tooling modification. |

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 |
|---|---|---|---|
| 1N4742A | VZ = 12 V ±5%, rd = 9 Ω, Pd = 1 W, DO-41 package | Higher power but looser voltage tolerance; requires PCB layout change due to larger DO-41 footprint | Select when >400 mW dissipation is needed and 12 V regulation suffices. |
| BZX79-C13 | VZ = 13 V ±5%, rd = 20 Ω, Pd = 400 mW, DO-35 package | Same power rating but higher impedance and wider tolerance; smaller DO-35 leads require retooling | Choose only if MHD lead pitch compatibility is not required and 20 Ω rd meets system regulation spec. |
Compared with 1N4742A and BZX79-C13, the HZS13NB3TA-E offers superior voltage tightness (B3 grade vs. ±5%), identical power rating to BZX79-C13 but lower dynamic resistance, and MHD packaging optimized for high-volume automated insertion - making it optimal for cost-sensitive, space-constrained industrial power rails where regulation precision matters.

FAQ
What is the exact zener voltage range for HZS13NB3TA-E at 5 mA?
The HZS13NB3TA-E has a guaranteed zener voltage range of 13.03 V to 13.62 V when tested at IZ = 5 mA and Ta = 25°C. This B3-grade specification reflects ±4.5% tolerance around the nominal 13.3 V center point, confirmed in Renesas document REJ03G0185-0300 Rev.3.00.
Does HZS13NB3TA-E support automatic insertion equipment?
Yes, the HZS13NB3TA-E uses the MHD package (JEITA GRZZ0002ZC-A) with 5 mm lead pitch, explicitly designed for high-speed automatic insertion. Its axial-leaded, cylindrical form factor and standardized lead spacing ensure compatibility with standard pick-and-place and wave-soldering systems.
What is the maximum allowable reverse current before regulation in HZS13NB3TA-E?
The HZS13NB3TA-E specifies a maximum reverse leakage current of 0.2 μA at VR = 10 V (i.e., 23% below nominal VZ). This ultra-low leakage ensures minimal parasitic loading in high-impedance reference networks and preserves battery life in always-on monitoring circuits using the HZS13NB3TA-E.
How does thermal derating affect HZS13NB3TA-E's power handling above 25°C?
HZS13NB3TA-E begins linear derating at 50°C ambient: its 400 mW rating reduces by approximately 3.3 mW/°C up to 150°C, reaching zero dissipation at ~170°C. This behavior is defined in Figure 3 of REJ03G0185-0300 and must be applied when designing for enclosure temperatures exceeding 50°C.
Is HZS13NB3TA-E rated for automotive or safety-critical applications?
No. Per Renesas quality grading (REJ03G0185-0300 Section 7), the HZS13NB3TA-E is classified as "Standard" grade, approved only for computers, office equipment, industrial robots, and consumer appliances - not for automotive, medical, aerospace, or life-support systems. Its use in such applications requires explicit written consent from Renesas Electronics.
