Product details

Overview

2SC3596E from SANYO is an NPN epitaxial planar silicon transistor designed for high-frequency video output stages in ultrahigh-definition CRT displays and color TV chroma circuits. It delivers f_T = 700 MHz (typ), V_CEO = −60 V, I_C = −300 mA, P_C = 1.2 W, and C_re = 1.8 pF at V_CB = −30 V, enabling wide-band amplification with low reverse transfer capacitance.

For engineers reviewing the 2SC3596E datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, TO-126 package mapping, complementary pairing with 2SA1402, saturation voltage behavior under I_C/I_B = 10, and real-world use cases in analog video signal paths.

Technical Context

The 2SC3596E employs SANYO's FBET (Flat Base Epitaxial Transistor) process to achieve high f_T and low C_re, supporting stable gain up to UHF frequencies in linear video output stages. Its complementary PNP counterpart is the 2SA1402, and both share identical TO-126 packaging and thermal derating curves.

It operates with V_CE(sat) ≤ −0.6 V at I_C = −100 mA / I_B = −10 mA, h_FE = 20–100 at I_C = −50 mA / V_CE = −10 V, and exhibits tight h_FE binning (Class C: 20–60, Class D: 60–120, Class E: 120–200, Class F: 200–400) per ordering code ENN1761B.

Key Specifications

Parameter	Value and Actual Design Meaning
f_T	700 MHz typ at V_CE = −10 V, I_C = −100 mA - enables stable wideband video amplification up to ~300 MHz fundamental.
V_CEO	−60 V - supports operation across CRT anode drive and chroma output swing without breakdown.
I_C (max)	−300 mA continuous - sufficient headroom for peak video current transients in 30–50 MHz bandwidth stages.
P_C	1.2 W at T_c = 25°C - requires minimal heatsinking in TO-126 mounting for sustained video output duty cycles.
C_re	1.8 pF at V_CB = −30 V, f = 1 MHz - minimizes Miller feedback distortion in high-gain common-emitter video amps.
h_FE	20–400 (binned Classes C–F) at I_C = −50 mA, V_CE = −10 V - allows precise DC bias setting and gain matching in differential pairs.
V_CE(sat)	≤ −0.6 V at I_C/I_B = 10 - ensures low conduction loss and minimal thermal rise in linear output stage operation.

Pinout & Package

SANYO TO-126 plastic power package (3-pin, vertical mount, metal tab connected to collector). Dimensions: 15.5 × 10.0 × 4.8 mm (L × W × H); tab center-to-pin-2 distance: 3.0 mm.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected to ground or negative rail in common-emitter video output; low-inductance path critical for HF stability.
2 (Collector)	Current source terminal	Internally bonded to metal tab; must be electrically isolated from heatsink unless circuit design permits collector-to-chassis connection.
3 (Base)	Control input	Drives with low-impedance source (≤ 1 kΩ) to minimize phase shift; sensitive to stray capacitance due to high f_T.

Key Features

Feature	Design Value
Ultrahigh f_T performance	700 MHz typical enables flat gain response through NTSC/PAL chroma band (3.58/4.43 MHz) and luminance harmonics.
Low reverse transfer capacitance	C_re = 1.8 pF reduces Miller effect, allowing stable >20 dB gain at 50 MHz without neutralization.
Complementary PNP pairing	Matched thermal and electrical characteristics with 2SA1402 for push-pull video output and balanced chroma drivers.
FBET process technology	Flat base geometry improves h_FE consistency and reduces base spreading resistance for tighter gain binning.
TO-126 thermal robustness	1.2 W dissipation with 150°C junction rating supports continuous operation in sealed CRT chassis environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-frequency NPN transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SC3838	f_T = 500 MHz (lower), V_CEO = −80 V (higher), C_re = 2.5 pF (higher), TO-126 package	Better voltage margin but reduced bandwidth and higher Miller capacitance limits use above 30 MHz	Select when higher breakdown voltage is prioritized over chroma fidelity or UHD video edge rates
MPSH10	f_T = 650 MHz, V_CEO = −25 V, I_C = −100 mA, TO-92 package, no h_FE binning	Lower power and voltage rating; unsuitable for CRT anode swing or sustained 300 mA loads	Acceptable only in low-power, low-voltage video preamp stages where TO-126 thermal capacity is unnecessary

Compared with 2SC3596E, the 2SC3838 trades bandwidth for ruggedness and the MPSH10 sacrifices power handling and thermal stability for small-signal convenience-neither offers the same combination of 700 MHz f_T, −60 V rating, −300 mA current, and binned h_FE in TO-126 required for CRT video output integrity.

FAQ

What is the maximum collector-emitter voltage rating for the 2SC3596E?

The 2SC3596E has an absolute maximum V_CEO rating of −60 V at T_a = 25°C. This rating applies under open-base conditions and defines the upper limit for safe operation in video output stages driving CRT cathodes or chroma loads. Exceeding this voltage-even momentarily-may cause irreversible avalanche breakdown. Derating is required above 25°C ambient per the published thermal curves.

Is the 2SC3596E pin-compatible with the 2SA1402?

No-the 2SC3596E (NPN) and 2SA1402 (PNP) share the same TO-126 package outline and pin numbering (Emitter–Collector–Base), but their polarity and biasing requirements are opposite. They are complementary *functional* pairs-not pin-compatible replacements. Swapping them without circuit redesign will result in immediate reverse-bias failure or no conduction.

What does the 'E' suffix in 2SC3596E indicate?

The 'E' suffix in 2SC3596E denotes the h_FE binning class per SANYO's ENN1761B specification: Class E corresponds to h_FE = 120–200 at I_C = −50 mA and V_CE = −10 V. This binning ensures predictable DC gain for stable biasing in video output stages without individual unit trimming.

Can the 2SC3596E be used in surface-mount designs?

No-the 2SC3596E is exclusively offered in the through-hole TO-126 package with a metal tab intended for mechanical mounting and thermal conduction to a heatsink. It has no surface-mount variant. Attempting SMT reflow or hand-soldering will damage the internal die bond wires and compromise f_T and C_re specifications.

What is the typical reverse transfer capacitance (C_re) of the 2SC3596E?

The 2SC3596E exhibits a typical reverse transfer capacitance (C_re) of 1.8 pF measured at V_CB = −30 V and f = 1 MHz. This low value directly contributes to reduced Miller effect in common-emitter configurations, supporting stable high-frequency gain without neutralization networks in video amplifier designs.
