Product details
Overview
SMDJ60CA from Taiwan Semiconductor is a bidirectional 3000W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with a working stand-off voltage of 60 V, breakdown voltage range 66.7–73.7 V, and clamping voltage of 96.8 V at 31.0 A peak pulse current. It protects telecom and industrial power rails against ESD, lightning surges, and load-switch transients.
For engineers reviewing the SMDJ60CA datasheet, SMDJ60CA pinout, SMDJ60CA application, or SMDJ60CA equivalent, key selection criteria include bidirectional clamping capability, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, 1.0 ps response time, 175°C max junction temperature, and DO-214AB mechanical compatibility for automated placement.
Technical Context
The SMDJ60CA uses a glass-passivated silicon junction optimized for high-energy transient suppression in bidirectional configurations. Its electrical characteristics-VWM = 60 V, VBR = 66.7–73.7 V @ 1 mA, and VC = 96.8 V @ 31.0 A-are specified per JEDEC standards and validated under 10/1000 µs waveform per R.E.A. definition.
Thermal performance is defined by RθJA = 75°C/W and RθJL = 15°C/W, enabling reliable operation up to 175°C junction temperature. It meets J-STD-020 moisture sensitivity level 1 and JESD 201 Class 2 whisker resistance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC60CA (Littelfuse) | Same VWM (60 V), slightly higher VC (100 V @ 30 A), DO-214AB package | Lower peak current rating (30 A vs. 31 A); identical ISO 7637-2 coverage | Preferred where tighter VC tolerance is not required and Littelfuse supply chain is prioritized |
| 1.5KE60CA (ON Semiconductor) | Through-hole DO-15 package, same VWM/VBR, VC = 96.8 V @ 31 A, PPK = 1500 W | Half the peak power rating; unsuitable for high-energy surges requiring 3000 W | Select only for legacy through-hole designs where board space allows and energy levels are ≤1500 W |
Compared with SAC60CA and 1.5KE60CA, the SMDJ60CA delivers full 3000 W surge capability in a surface-mount footprint, enabling compact, high-density layouts while meeting stringent automotive and industrial transient immunity standards without compromising clamping performance.

FAQ
What is the clamping voltage of SMDJ60CA and under what test condition is it specified?
The SMDJ60CA has a maximum clamping voltage (VC) of 96.8 V, measured at a peak pulse current (IPPM) of 31.0 A using the standard 10/1000 µs double-exponential waveform per R.E.A. definition. This value ensures downstream circuitry remains within safe operating limits during high-energy transients. The SMDJ60CA maintains this clamping performance across its rated junction temperature range of –55°C to +175°C.
Is SMDJ60CA unidirectional or bidirectional, and how is polarity indicated?
SMDJ60CA is a bidirectional TVS diode, meaning it clamps transients of either polarity symmetrically. Unlike unidirectional variants (e.g., SMDJ60A), it carries the "CA" suffix and has no cathode band marking. Its DO-214AB package features two identical terminals, and the device is marked "DGK" - confirming its bidirectional configuration per Taiwan Semiconductor's ordering code convention.
Does SMDJ60CA meet automotive transient immunity standards?
Yes, the SMDJ60CA meets ISO 7637-2 requirements for Pulse 1 (inductive load disconnect), Pulse 2a/2b (battery line transients), and Pulse 3a/3b (capacitive coupling), making it suitable for automotive body control modules and infotainment power supplies. Its 3000 W peak power rating and sub-1 ps response time ensure robust protection against real-world vehicle electrical disturbances. SMDJ60CA is not qualified to AEC-Q101 but is widely used in non-safety-critical automotive subsystems.
What is the thermal resistance and maximum power dissipation of SMDJ60CA?
The SMDJ60CA has a junction-to-ambient thermal resistance (RθJA) of 75°C/W and junction-to-lead resistance (RθJL) of 15°C/W. Its steady-state power dissipation (PD) is 6.5 W at 25°C ambient, but it is rated for 3000 W peak pulse power under short-duration (1 ms) non-repetitive conditions. Derating is required above 25°C per the published pulse derating curve in the datasheet.
Can SMDJ60CA be used in place of SMDJ60A in an existing design?
No - SMDJ60CA and SMDJ60A are not interchangeable without circuit review. SMDJ60A is unidirectional (cathode-banded, clamps only negative transients), while SMDJ60CA is bidirectional (no band, clamps both polarities). Substituting SMDJ60CA for SMDJ60A may cause unintended conduction in DC-biased circuits. Always verify bias conditions and transient polarity requirements before replacement. The SMDJ60CA must be used only where bidirectional protection is explicitly needed.
