Product details
Overview
TTA006B from Toshiba Electronic Devices & Storage Corporation is a silicon PNP epitaxial bipolar transistor designed for high-voltage linear amplification, featuring VCEO = −230 V (min), fT = 70 MHz (typ.), and Cob = 30 pF (typ.). It operates in audio-frequency and power amplifier stages where high breakdown voltage and moderate frequency response are required.
For engineers reviewing the TTA006B datasheet, TTA006B pinout, TTA006B application, or TTA006B equivalent, this device serves as a complementary high-voltage PNP switch/amplifier to TTC011B in push-pull output stages, requiring attention to junction temperature derating and safe operating area limits under pulsed load conditions.
Technical Context
The TTA006B employs a planar epitaxial structure optimized for stable DC current gain (hFE ≥ 100 at IC = −0.1 A) and low collector output capacitance. Its −230 V collector-emitter breakdown voltage enables use in high-rail analog power stages without cascading devices.
Dynamic performance centers on 70 MHz transition frequency at VCE = −10 V and IC = −0.1 A, supporting wideband audio amplification up to ~10 MHz with minimal phase shift. The TO-126N package provides mechanical robustness and thermal dissipation (PC = 10 W at Tc = 25 °C) suitable for discrete Class-A/AB output stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −230 V min: supports rail voltages up to ±200 V in symmetrical amplifier supplies |
| fT | 70 MHz typ.: enables full-audio bandwidth amplification with margin for stability compensation |
| Cob | 30 pF typ. at VCB = −10 V: reduces Miller effect in common-emitter configurations |
| hFE | 100 min at IC = −0.1 A: ensures predictable biasing in fixed-current mirror or emitter-follower drivers |
| VCE(sat) | −1.5 V max at IC = −0.5 A, IB = −50 mA: limits conduction loss in saturated switching applications |
| Tj max | 150 °C: requires heatsinking when dissipating >1.5 W continuously at ambient >50 °C |
Pinout & Package
TTA006B is housed in a TO-126N (TOSHIBA 2-8U1A) plastic package with 3 leads: Emitter (Pin 1), Collector (Pin 2), Base (Pin 3). The case is electrically connected to the collector terminal; isolation is not guaranteed - external creepage/clearance must be maintained per system safety requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal for PNP operation | Connected to most positive supply rail in common-emitter amplifier configurations |
| 2 (Collector) | Main output current path | Internally tied to package tab; requires insulated mounting if referenced to non-ground potential |
| 3 (Base) | Control input for minority-carrier injection | Requires current-limited drive (IB ≤ −0.5 A) to avoid second breakdown during transient overloads |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO rating | −230 V minimum enables single-transistor operation in ±150 V power amplifier rails |
| Low Cob | 30 pF typical minimizes feedback capacitance in high-gain CE stages, easing stability compensation |
| Complementary pairing | Matched electrical profile with TTC011B allows symmetric push-pull output stage design |
| TO-126N thermal capability | 10 W power dissipation at case temperature of 25 °C supports discrete output stage heat management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-voltage amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD2955G | VCEO = −70 V (lower), fT = 3 MHz (much lower), TO-220 package | Not suitable for >±100 V rails or wideband audio; limited to low-frequency power regulation | Select only if rail voltage <±60 V and bandwidth <100 kHz is acceptable |
| 2SA1943 | VCEO = −230 V (same), fT = 30 MHz (lower), higher Cob = 120 pF, TO-3P package | Compatible rail voltage but reduced bandwidth and higher Miller capacitance limit slew rate | Acceptable for Hi-Fi audio where bandwidth beyond 5 MHz is unnecessary; larger footprint |
Compared with MJD2955G and 2SA1943, the TTA006B delivers superior high-frequency linearity and rail tolerance in compact TO-126N packaging, making it optimal for space-constrained wideband amplifier designs requiring >5 MHz bandwidth and ±150 V operation.

FAQ
What is the maximum continuous collector current for TTA006B?
The TTA006B has an absolute maximum DC collector current (IC) rating of −1 A at Ta = 25 °C. However, sustained operation above −0.5 A requires active heatsinking to maintain junction temperature below 150 °C, as specified in the Safe Operating Area curve (Fig. 7.7). Derating is mandatory above 50 °C ambient.
Is TTA006B pin-compatible with TTC011B?
No - TTA006B (PNP) and TTC011B (NPN) are complementary devices with identical TO-126N packaging and matching pinout (Emitter–Collector–Base), but opposite polarity. Their pin assignments align mechanically and electrically for push-pull layout, but they are not interchangeable without circuit redesign.
Does TTA006B meet RoHS requirements?
Yes, TTA006B is RoHS compatible per Directive 2011/65/EU, marked as [[G]]/RoHS COMPATIBLE or [[G]]/RoHS [[Pb]] on the package. Full compliance documentation, including substance declarations and test reports, is available through Toshiba's official sales channels.
What is the safe operating area (SOA) limitation for TTA006B in pulse applications?
The guaranteed maximum SOA for TTA006B (Fig. 7.7) defines allowable combinations of VCE and IC for pulse widths up to 10 ms. At VCE = −150 V, peak IC must remain below −0.3 A for tw = 1 ms; at VCE = −50 V, IC may reach −1.2 A. Exceeding SOA risks second breakdown and permanent failure.
Can TTA006B be used in switching power supplies?
TTA006B is optimized for linear operation - its relatively slow turn-off (due to minority-carrier storage) and lack of specified switching times make it unsuitable for high-frequency SMPS. It may serve in low-frequency (<10 kHz), low-duty-cycle protection or sequencing circuits, but dedicated switching transistors are strongly preferred.
