Product details

Overview

RD13S(0)-T1-AT from Renesas Electronics is a 200 mW, 2-pin Super Mini Mold zener diode with a nominal zener voltage of 13.33 V to 14.00 V (Class B3), dynamic impedance ≤35 Ω at 5 mA, and reverse current ≤2 μA at 10 V. It serves as a precision voltage reference or surge absorber in low-power analog signal conditioning and power rail stabilization circuits.

For engineers reviewing the RD13S(0)-T1-AT datasheet, RD13S(0)-T1-AT pinout, RD13S(0)-T1-AT application, or RD13S(0)-T1-AT equivalent, key selection criteria include its 13.33–14.00 V zener tolerance band, 200 mW power rating on PCB, 150 °C max junction temperature, and suitability for constant-voltage regulation in space-constrained consumer and industrial control modules.

Technical Context

This device operates in reverse-biased breakdown mode with sharp knee characteristics, enabling stable voltage clamping across varying load currents. Its E24-standardized zener voltage and low dynamic impedance ensure minimal output variation under transient load steps.

The RD13S(0)-T1-AT is rated for 85 W non-repetitive reverse surge power at 10 μs pulse width and exhibits a typical zener voltage temperature coefficient of +0.07 %/°C in the 12–15 V range, supporting predictable thermal drift behavior in ambient temperatures from –55 °C to +150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	13.33–14.00 V (Class B3, tested at 5 mA pulsed); defines precise clamping threshold for overvoltage protection.
Power Dissipation (P)	200 mW at T_A = 25 °C on standard PCB; limits continuous thermal loading in compact layouts.
Dynamic Impedance (Z_Z)	≤35 Ω at I_Z = 5 mA; ensures low output impedance for stable regulation under small-signal variations.
Reverse Current (I_R)	≤2 μA at V_R = 10 V; guarantees minimal leakage in standby or high-impedance bias networks.
Junction Temperature (T_j)	–55 to +150 °C; supports operation in extended industrial environments without derating below 125 °C.
Surge Power (P_RSM)	85 W at t = 10 μs (single pulse); enables robust transient suppression against ESD or inductive kickback.
Package	2-pin Super Mini Mold (SOD-323 equivalent footprint); 1.25 ±0.1 mm body length, 0.9 ±0.1 mm width, 0.3 ±0.05 mm thickness.

Pinout & Package

RD13S(0)-T1-AT uses a 2-pin Super Mini Mold package (equivalent to JEDEC SOD-323) with cathode indicated by a band. No internal terminals beyond anode and cathode; polarity must be observed for correct reverse-bias operation.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward conduction terminal / reference ground node	Connected to lower-potential side of circuit; forms return path during zener conduction.
Cathode	Zener breakdown terminal / regulated output node	Marked with band; connected to higher-potential rail to enable controlled reverse breakdown at V_Z.

Key Features

Feature	Design Value
Sharp breakdown characteristic	Enables clean voltage clamping with minimal knee spread - critical for accurate reference generation.
E24-standard zener voltage grading	Ensures consistent binning across production lots for predictable system-level voltage margining.
Low dynamic impedance (≤35 Ω)	Minimizes output voltage shift under 1–10 mA load changes - suitable for feedback sensing nodes.
150 °C maximum junction temperature	Supports reliable operation in sealed enclosures or near heat-generating components without forced cooling.
85 W surge power capability	Withstands short-duration transients per IEC 61000-4-5 Level 3 without degradation - reduces need for external TVS.

Equivalent & Alternatives

The following parts are listed as comparable options for similar zener diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MMBZ5242B	13 V nominal (12.35–13.65 V), 200 mW, SOD-123 package (larger footprint), 30 Ω Z_Z	Higher thermal mass but requires 0.6 mm × 1.2 mm layout vs. RD13S(0)-T1-AT's 0.9 mm × 1.25 mm	Select when higher surge energy handling (100 W) or legacy SOD-123 compatibility is required.
Vishay BZX584-C13	13 V nominal (12.35–13.65 V), 200 mW, SOD-323 package, 40 Ω Z_Z, 5 μA I_R at 10 V	Same footprint but higher leakage and less tight V_Z tolerance than RD13S(0)-T1-AT Class B3	Select when cost sensitivity outweighs need for sub-2 μA leakage or ±0.67 V V_Z window.

Compared with MMBZ5242B and BZX584-C13, RD13S(0)-T1-AT offers the narrowest V_Z tolerance (±0.67 V), lowest leakage (≤2 μA), and smallest SOD-323-compatible form factor - making it optimal for high-accuracy, space-constrained voltage referencing where thermal and leakage margins are critical.

FAQ

What is the exact zener voltage range specified for RD13S(0)-T1-AT?

The RD13S(0)-T1-AT is classified as Class B3 in the RD2.0S–RD150S series, with a guaranteed zener voltage range of 13.33 V to 14.00 V at 5 mA test current. This specification is confirmed in the August 2006 Renesas datasheet D11444EJ6V0DS, page 4, and applies strictly to the RD13S variant with B3 suffix - not to broader RD13S family bins.

Does RD13S(0)-T1-AT have a defined cathode marking, and how is polarity identified?

Yes, RD13S(0)-T1-AT uses a cathode band for polarity identification, as shown in the package drawing on page 2 of the Renesas datasheet D11444EJ6V0DS. The band marks the cathode terminal; the unmarked end is the anode. Correct orientation is essential for reverse-bias operation - forward connection will result in ~0.7 V drop and no zener regulation.

What is the maximum allowable reverse surge power for RD13S(0)-T1-AT, and under what conditions?

RD13S(0)-T1-AT is rated for 85 W non-repetitive reverse surge power at a pulse width of 10 μs, as specified in the Absolute Maximum Ratings table (page 2). This rating assumes single-pulse application and is validated per Figure 12 in the datasheet. Repetitive surges require derating based on thermal time constants shown in Figure 11.

Can RD13S(0)-T1-AT be used in automotive applications, and what quality grade does it carry?

RD13S(0)-T1-AT carries the "Standard" quality grade per Renesas' classification (page 7 of datasheet), approved for computers, office equipment, communications gear, and industrial robots - but not for automotive transportation systems. For automotive use, Renesas explicitly requires "High Quality" grade parts with documented AEC-Q200 qualification, which RD13S(0)-T1-AT does not possess.

How does the dynamic impedance of RD13S(0)-T1-AT affect its performance in voltage reference circuits?

RD13S(0)-T1-AT has a maximum dynamic impedance of 35 Ω at 5 mA, meaning a 1 mA change in zener current produces ≤35 mV output variation. This low Z_Z stabilizes reference voltage under varying load or source impedance - especially valuable in feedback networks for LDOs or ADC references where ripple rejection and accuracy are design-critical parameters for RD13S(0)-T1-AT.
