Product details
Overview
MJD32C-13 from Diodes Incorporated is a 100V PNP high-voltage bipolar junction transistor in TO252 (DPAK) package, rated for −3A continuous collector current and −100V collector-emitter breakdown voltage. It serves as a power switching or linear amplification device in industrial DC-DC converters, motor drive stages, and high-side load switches where robust negative-rail control is required.
For engineers reviewing the MJD32C-13 datasheet, MJD32C-13 pinout, MJD32C-13 application, or MJD32C-13 equivalent, key selection criteria include verified VCEO = −100V, IC = −3A, VCE(sat) ≤ −1.2V at −3A/−375mA, hFE ≥ 25 at −1A, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This PNP transistor operates with emitter-referenced biasing and requires base current sinking to enable conduction. Its safe operating area (SOA) supports single-pulse currents up to −5A and maintains thermal stability via low RθJL = 3.6°C/W to the exposed collector pad.
Designed for high-voltage switching, it features complementary pairing with the NPN MJD31C, enabling push-pull or H-bridge topologies. The −6V VEBO rating and −1μA ICEO ensure stable cutoff under reverse-biased base-emitter conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −100 V: Enables use in 48V–80V DC bus systems without derating |
| IC (continuous) | −3 A: Supports sustained 36W dissipation at VCE = −12V in TO252 with 50mm×50mm copper |
| VCE(sat) | ≤ −1.2 V @ −3A/−375mA: Limits conduction loss to ≤3.6W in saturated switch mode |
| hFE | 25–50 @ −1A to −3A: Ensures predictable base drive sizing across operating range |
| fT | 3.0 MHz: Supports switching up to ~300 kHz with adequate gain margin |
| RθJL | 3.6 °C/W: Enables direct thermal coupling to PCB copper for passive cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-voltage switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD32C-1-E | Same die, tape-and-reel variant with different reel size (1,000 pcs vs. 2,500 pcs); identical electrical specs | No functional difference; used in lower-volume prototyping or space-constrained assembly lines | Select when matching existing BOM line item or optimizing feeder setup |
| PN3565 | TO92 package, −60V VCEO, −0.5A IC; lacks AEC-Q101, higher VCE(sat) (−1.5V) | Limited to low-power signal switching or non-automotive consumer applications | Only acceptable if voltage stress <60V and current <500mA; not drop-in compatible |
Compared with MJD32C-13, the MJD32C-1-E offers identical performance in smaller reels for flexibility, while PN3565 trades voltage/current capability and qualification for cost and through-hole compatibility-making it unsuitable for automotive or industrial 48V+ systems.

FAQ
What is the maximum allowable case temperature for continuous operation?
The MJD32C-13 has an operating junction temperature range of −55°C to +150°C. With its RθJL = 3.6°C/W, the maximum recommended case temperature is +125°C when mounted on a 50mm × 50mm 2oz copper pad under still air, ensuring 25°C margin below TJ(max) at full −3A load.
Can MJD32C-13 be used in parallel configurations?
Parallel operation is not recommended due to inherent hFE variation (25–50) and negative temperature coefficient of VCE(sat), which can cause current imbalance. If required, external emitter resistors (≥0.1Ω) and matched devices with binning data must be used-consult Diodes' AN-2001 for layout guidance.
Is the exposed collector pad electrically isolated from other terminals?
No-the TO252 exposed collector pad is electrically connected to the collector terminal. It must be routed to the same net as the collector pin and thermally bonded to a dedicated copper pour. Isolation requires physical separation from adjacent traces per IPC-2221 creepage/clearance rules for −100V systems.
Does MJD32C-13 support pulsed operation beyond its DC ratings?
Yes-its peak pulse collector current ICM is −5A for durations ≤100μs (duty cycle ≤2%). Safe operation requires adherence to the SOA curve in the datasheet, especially limiting VCE × IC product during pulses and verifying transient thermal impedance at the intended pulse width.
